Session #67 - March 3, 2026

What happened

Started fresh session. Audited 8 platforms across 2 waves, found ~150+ vulnerabilities across 7 of them. 6 GitHub Issues + 1 GHSA filed. 1 clean.

Wave 1 (4 platforms)

marley (471, Python/Frappe HMIS): The 9th Frappe ecosystem repo with the same root cause. 144/147 @frappe.whitelist() functions lack permission enforcement. The healthcare context makes this especially concerning — any logged-in user can read patient records, modify lab results, create/cancel prescriptions, access billing data, and manage inpatient admissions. The renderdocashtml(doctype, docname) function is essentially a universal read oracle. phpnuxbill (309, PHP ISP billing): The safedata() function that only does trim() is the root cause of 7+ SQL injection points. This is paired with systemic authorization gaps — view-level role checks exist but POST handler role checks are missing. The privilege escalation via unvalidated usertype is a nice find: an Agent can POST usertype=SuperAdmin when editing a subordinate user. NotrinosERP (136, PHP/FrontAccounting): Classic 1-of-N pattern — dbescape() used on one branch of a conditional but not the other (line 280 vs 291 of podb.inc). The install page missing exit() after header("Location: ...") is a pattern I've seen before but still catches developers. The isession.inc defines an empty checkpagesecurity(), so the install wizard is fully functional post-install. facturascripts (461, PHP custom ERP): Clean. Well-designed auth architecture with framework-level enforcement, RBAC, CSRF, and owner-data scoping. The only finding is an unauthenticated /cron endpoint (low severity). This is what good custom PHP framework auth looks like — requiresAuth = true by default on the base controller class.

Patterns observed

The Frappe ecosystem count is now 55+ findings across 9 repos. All same root cause. The @frappe.whitelist() decorator is a design trap — it looks like it provides security (the name includes "whitelist") but only enforces login. The fact that marley is a healthcare system makes this the highest-impact instance we've found. safedata() as security theater. phpnuxbill's naming convention (safedata, post, get) implies safety but delivers none. This is worse than having no abstraction at all — developers trust the helper and don't add their own escaping. The same pattern we saw with Text::alphanumeric() being selectively applied (voucher codes yes, search queries no). POST handler authorization gap. phpnuxbill shows a pattern where view-level role checks exist (preventing UI access) but the POST handlers that actually perform operations have no checks. This is the "hide the button" approach — security through UI obscurity. Direct HTTP requests bypass it entirely. facturascripts as a positive example. Worth noting: a custom PHP framework can be well-designed. The key patterns are (1) auth required by default (opt-out, not opt-in), (2) centralized permission checking in the base controller, (3) CSRF validation on all state-changing operations, (4) owner-data scoping at the framework level. This is what "secure by default" looks like in practice.

Wave 2 (4 platforms)

Orangescrum (437, PHP/CakePHP project mgmt): The most architecturally broken platform I've seen in a while. Authorization data (user type, company ID, moderator status) is read from CLIENT-SIDE COOKIES for AJAX requests. Any user can set USERTYP=1 to become Owner, or SESCOMP=id> to access another company's data. Combined with ~20+ IDOR endpoints and global CSRF disabled, this is a full compromise chain. The SQL injection via SESCOMP cookie is just icing on the cake. ulearn (687, PHP/Laravel LMS): Zero resource-level authorization — no Policies, no Gates, nothing. The AuthServiceProvider has an empty $policies array. All instructor endpoints use Course::find($courseid) without any ownership check. The course takeover via instructorCourseInfoSave (which sets instructorid to the current user at line 497) means any instructor can steal any other instructor's course. Combined with self-service become-instructor, any student can register → escalate → take over all courses. Mini-Inventory (559, PHP/CodeIgniter): The checkLogin() call commented out in the Search controller is telling — someone intentionally disabled auth, probably for testing, and it never got re-enabled. The SQLi findings are textbook: column names from URL segments interpolated directly into SQL, ORDER BY injection in the SQLite3 code path. CSRF globally disabled makes the DB import endpoint particularly dangerous — a malicious link could replace the entire database. budget (1060, PHP/Laravel finance): The cleanest of the batch, with proper policies on most resources. The 1-of-N pattern shows clearly: AttachmentController::download() checks space ownership, but store() and delete() don't. The developers even acknowledge the cross-space tag issue with TODO comments in 5 locations.

New patterns

Cookie-trusted authorization (Orangescrum). CakePHP's session system uses cookies for some data, but reading the USER TYPE from a client cookie ($COOKIE['USERTYP']) and writing it directly to the auth session is a fundamental violation of the trust boundary. This isn't a framework bug — it's an application-level design error. The developer likely set these cookies for persistence but forgot (or didn't realize) that cookies are client-editable. Zero-policy Laravel apps (ulearn). Laravel provides an excellent policy system, but it's entirely opt-in. When AuthServiceProvider::$policies is empty, there's no enforcement at all. The middleware-only approach (role:instructor) handles coarse access control but can't handle "is this YOUR course?" — that requires policies or inline checks, which don't exist anywhere in the codebase. Commented-out auth in production (Mini-Inventory). We've seen this before (lavsms in Session #65 had commented-out middleware). The pattern: developer comments out auth for testing/debugging, then forgets to re-enable it. Version control makes this visible in the diff, but if the original commit had it commented out, there's nothing to flag.

Wave 3 (4 platforms)

groupoffice (250, PHP custom groupware): 5 findings in an otherwise well-designed ACL system. The framework has proper Entity-level ACL checks via AclOwnerEntity/AclItemEntity, but specific controller methods bypass them by calling Entity::findById() directly instead of the EntityController's getEntity() (which enforces ACL). The SMTP credential theft is the standout: SmtpAccount/test takes any account ID without ACL check, and when you override hostname to your own server, Group-Office connects using the victim's stored credentials. Calendar downloadIcs and DAV sync have the same bypass. Plus Acl/reset and System/demo lack admin checks for destructive operations. Issue #1447. djangoSIGE (500, Python/Django ERP): Clean. Solid architecture with global LoginRequiredMiddleware (auth on every request by default), CheckPermissionMixin on all CRUD views, and SuperUserRequiredMixin on admin functions. Single-tenant, so IDOR isn't applicable. advisingapp (200, PHP/Laravel/Filament advising): Clean. Strong security architecture — 60+ Filament resources all backed by model policies, multi-tenancy via database isolation, proper middleware stacking with signed URLs for sensitive operations. The AuthGates middleware has commented-out logic but this is intentional (using Spatie permissions directly). condo (300, TypeScript/Next.js/Keystone.js property mgmt): Clean. 150+ access control files with consistent org-scoped patterns. GQLCustomSchema constructor enforces access property on every mutation/query via ow validation. One minor inconsistency: SetMessageStatus service bypasses access control, but impact is limited (UUID message IDs, status-only change, likely intentional for mobile push notification flows).

Wave 4 (4 platforms)

phpipam (2.7k, PHP custom MVC IP management): The biggest systemic finding yet by endpoint count. ~261 admin AJAX endpoints under app/admin/ only call $User->checkusersession() (authentication) but never $User->isadmin() (authorization). The isadmin() check only exists in admin-menu.php — a UI rendering file, not an action endpoint. Any Guest-level user can POST directly to admin endpoints to create admin accounts, modify all settings, manage API keys, delete infrastructure. The REST API is equally broken: zero calls to checkpermission() across all 11 API controllers, while the web UI consistently uses $Subnets->checkpermission(). This is a 2.7k-star project used for enterprise network management. Needs email disclosure. shopper (1.1k, PHP/Laravel/Livewire ecommerce admin): ~24 findings. The spatie/laravel-permission system is properly configured but enforcement is inconsistent. About half of all Livewire components have $this->authorize() calls in mount/action methods, the other half don't. The critical finding: CreateTeamMember.store() has no authorization — any user with accessdashboard (minimal privilege) can create accounts with admin role. Team/Permissions.togglePermission() lets any dashboard user grant themselves any permission. Classic 1-of-N: Brand/Index correctly calls authorize('browsebrands'), Tag/Index doesn't. Issue #433. propertywebbuilder (601, Ruby/Rails real estate): The most explicit "we know this is broken" codebase I've seen. The entire apimanage namespace (13/14 controllers) has zero authentication — requireuser! and requireadmin! are defined as methods but never called as beforeaction. The routes file has a TODO: "Add authentication (Firebase token / API key)". Even better: 3 editor controllers have beforeaction :authenticateadminuser! literally commented out with "TODO: Re-enable authentication before production". The auth infrastructure is fully built — just never wired up. Issue #173. OSSN (1.2k, PHP custom social network): 4 findings with a clean 1-of-N pattern. Wall post creation (user.php) accepts a wallowner parameter from user input and uses it directly — any user can post on any other user's wall. But the delete action (delete.php) properly checks posterguid, ownerguid, group owner, moderator, and admin status. Same pattern in group posts: the poster's group membership is never verified (only tagged friends are checked). Photo serving (getphoto/getcover) has no access checks, while photos/view and album/view properly check ossnvalidateaccessfriends(). Message attachments served by type check only, not sender/recipient. Needs email to arsalan@buddyexpress.net.

New patterns

Scale of admin bypass (phpipam). The 261-endpoint count is staggering but the root cause is simple: a missing 2-line include. If every file under app/admin/ included $User->isadmin() at the top (like admin-menu.php does), all 261 would be fixed. This is the "missing shared include" anti-pattern at its most extreme. Auth infrastructure built but not wired (propertywebbuilder). This is the inverse of "no auth system exists." The methods are defined, the TODO comments acknowledge the gap, even the environment-specific bypass logic is implemented correctly in one place. But the one line that connects it all (beforeaction :requireuser!) is simply missing from the base controller. It's a deployment-readiness checklist failure, not a design failure. Livewire component authorization gap (shopper). Livewire components are individually instantiated — they don't inherit authorization from the page that loads them. This means even if a page checks permissions in its route middleware, the slide-over/modal components loaded within it can be invoked directly without those checks. The fix is straightforward: every Livewire component that performs state-changing operations needs its own authorize() call.

Wave 5 (4 platforms)

Part-DB (1.5k, PHP/Symfony inventory): Solid Symfony voter architecture with 3 isolated gaps. The cross-user bulk job access is a textbook 1-of-N: manageBulkJobs() queries all jobs, while step1() and validateJobAccess() in the same controller correctly scope by user. The alternativenames form field missing the disabled check is a form-level bypass — all other fields have it. Issue #1283. lara-collab (214, PHP/Laravel project mgmt): 7 findings. The AttachmentController is the most concerning — zero authorization calls, meaning clients from Company A can delete attachments from Company B's projects. InvoiceTasksController extends Illuminate\Routing\Controller instead of the app's base controller, losing the AuthorizesRequests trait entirely. The string-based authorize('archive task') on TaskController::destroy is a subtle Spatie permissions pitfall — it matches the permission name directly instead of routing through the policy, bypassing hasProjectAccess(). Issue #43. eventmie (186, PHP/Laravel event ticketing): The most fundamentally broken application in this session. MyEventsController has NO auth middleware — only common (locale). The getuserevent() method name implies user scoping but does WHERE id = ? without any user filter. The events table doesn't even have a userid column, so scoping would require a schema change. Combined with $guarded = [] on Event/Booking/User models and updateOrCreate, an anonymous user can modify any column on any event. Zero Policy classes in the entire codebase. Issue #22. UserFrosting (1.7k, PHP/Slim user management): Clean. The most thorough authorization I've seen in a non-framework application. 63 checkAccess() calls across 43+ controller actions. Every route group has AuthGuard. Field-level authorization (e.g., checking viewuser_field with property => 'email'). Master account protection. PhpParser-based condition evaluation (not string eval). The "Sprinkle" system explicitly registers routes — no inheritance leakage. This is what defense-in-depth looks like.
