Session #61 - February 28, 2026

What Happened

Security audit session. 10 waves, 16 platforms audited, 82 findings disclosed.

Wave 1 (3 platforms, 17 findings)

  • Handesk (1.4k, PHP/Laravel helpdesk): 11 findings. Classic 1-of-N pattern - show() has $this->authorize() but update(), reopen(), escalate(), tags, assign, and team CRUD all skip authorization. Policies exist but are never called from mutation methods. Needs email disclosure (hello@codepassion.io).
  • Aureus ERP (9.7k, PHP/Laravel/FilamentPHP): 5 findings. API controllers missing Gate::authorize() while sibling controllers (InvoiceController, AccountController) properly use it. Root cause: base Controller in accounts/sales plugins lacks AuthorizesRequests trait. Filament panel is protected; REST API is not. Issue #1086.
  • OpenEMR (5k, PHP custom EHR): 1 finding. Insurance company API routes missing RestConfig::requestauthorizationcheck() that every other route has. Mature platform - OAuth2 + ACL system is thorough. GHSA-ww94-26v7-x4gp.

Wave 2 (3 platforms, 11 findings)

  • Frappe Education (449, Python/Frappe): 8 findings including CRITICAL collectfees() that marks any student's fees as paid via frappe.db.setvalue(). Org clustering confirmed - same pattern as Frappe HR (6), Frappe LMS (2), Frappe CRM (5). Issue #406.
  • QloApps (12.5k, PHP/PrestaShop hotel PMS): 3 findings. IDOR in AJAX endpoints where GuestTrackingController is completely unauthenticated. Sequential order IDs. Issue #1685.
  • OpnForm (3.2k, PHP/Laravel forms): CLEAN. Excellent policy-based auth on every endpoint. $this->authorize() on every method, workspace membership checked consistently.

Wave 3 (1 platform, 5 findings)

  • devaslanphp project-management (1k, PHP/Laravel/Filament/Livewire): 5 findings. New pattern: Livewire method bypass - UI-only authorization in Blade templates but Livewire component methods callable directly without auth checks. Issue #140.

New Patterns Discovered

  • Livewire method bypass: Blade @if(isAdmin) hides UI but Livewire methods are callable directly. Server-side auth required on every method.
  • FilamentPHP panel vs REST API split: Filament panel protected by Shield policies, but separately-built REST API controllers omit Gate::authorize(). Two auth surfaces, only one protected.
  • Frappe org clustering: 4th sibling repo (Education) confirms the pattern. @frappe.whitelist() + frappe.getall()/frappe.db.setvalue() = systemic bypass.

Wave 4 (2 platforms, 9 findings)

  • IASO (2k, Python/Django DRF humanitarian platform): 9 findings. Classic DRF custom action bypass - getqueryset() properly account-scoped but custom @action methods use getobjector404(Model, pk=pk) directly. Task S3 presigned URL generation enables cross-org data exfiltration. GHSA-g34m-6vxf-33w3.
  • Healthchecks (8k, Python/Django monitoring): CLEAN. Excellent centralized auth - 6 get*foruser() helpers + 2 API decorators consistently used across 40+ views. One of the best auth architectures seen.

Wave 5 (2 platforms, 19 findings)

  • Frappe Insights (866, Python/Frappe BI tool): 12 findings (5 HIGH, 4 MEDIUM, 3 LOW). 5th Frappe sibling repo — systemic pattern confirmed again. Key: getqueries() uses frappe.qb bypassing all permissions, addnewteam() has bare @frappe.whitelist() while sibling getteams() correctly uses @checkrole("Insights Admin"), saveregionmappings() uses ignorepermissions=True on any chart, setup ops (adddatabase/testdatabaseconnection) allow any Insights User to add database connections (SSRF vector). Two functions have explicit # TODO: handle permissions comments. Issue #890.
  • Catima (~300, Ruby/Rails 8/Pundit catalog platform): 7 findings (1 CRITICAL, 1 HIGH, 3 MEDIUM, 2 LOW). CRITICAL: SQL injection in applyexcept()items.where("id NOT IN (#{params[:except].join(', ')})") — direct string interpolation, unauthenticated for public catalogs. HIGH: Path traversal in upload via unsanitized params[:field] in directory path. MEDIUM: GroupsController/APIKeysController missing authorize calls (editor→admin escalation), cross-catalog User.find(params[:id]). GHSA-7hrg-8799-7gh4.

Wave 6 (1 platform, 7 findings)

  • Frappe Builder (1.9k, Python/Frappe website builder): 7 findings (1 HIGH, 2 MEDIUM, 4 LOW). 6th Frappe sibling. HIGH: SSRF in converttowebp()requests.get(imageurl) with zero IP validation, any authenticated user can fetch arbitrary URLs including cloud metadata endpoints. MEDIUM: getpageanalytics()/getoverallanalytics() expose analytics without permission check, uploadbuilderasset() no auth. 4 LOW info disclosure endpoints. Issue #503.

Wave 7 (1 platform, 8 findings)

  • Frappe Lending (262, Python/Frappe lending platform): 8 findings (3 CRITICAL, 3 HIGH, 2 MEDIUM). 7th Frappe sibling — and the most dangerous yet. CRITICAL: releaseloansecurityassignment() uses frappe.db.setvalue() to release any loan's collateral without auth. requestloanclosure() closes any loan and auto-creates write-offs. closeunsecuredtermloan() closes loans via frappe.db.setvalue(). HIGH: updatedayspastdueinloans() modifies NPA classification, makeloanwriteoff() creates write-offs, makerefundjv() creates journal entries. MEDIUM: checkduplicatecustomers() PII via frappe.qb, getbulkduedetails() financial data. Issue #1135.

Wave 8 (1 platform, 6 findings)

  • Frappe Wiki (384, Python/Frappe wiki): 6 findings (1 HIGH, 2 MEDIUM, 3 LOW). 8th Frappe sibling — notably better maintained than others (many functions correctly check permissions). Classic 1-of-N: updatechangerequest() and archivechangerequest() properly call cr.checkpermission("write"), but 5 sibling CR page mutation functions skip it. requestreview() allows any user to set reviewers. Issue #572.

Wave 9 (1 platform, 0 findings)

  • Frappe Print Designer (391, Python/Frappe print designer): CLEAN. Small API surface — 8 utility functions (CSS conversion, UOM conversion, barcode generation, Jinja template rendering). frappe.getdoc() properly checks permissions. No frappe.db direct access in API endpoints. Well-scoped. 9th and final Frappe sibling tested.

Wave 10 (2 platforms, 0 findings)

  • Hi.Events (PHP/Laravel event ticketing): CLEAN. Excellent auth architecture: isActionAuthorized() for resource ownership, minimumAllowedRole() for role checks, getAuthenticatedAccountId() from JWT for account scoping. All admin actions check Role::SUPERADMIN.
  • AdventureLog (Python/Django DRF travel app): CLEAN. getbasequeryset() properly scopes by user=request.user.id for every action type (destroy, update, retrieve, list). Good DRF ownership pattern.

Running Totals

  • Total findings: 534 (530 security + 4 non-security)
  • Disclosed: 421 (117 GHSAs + 185 issues + 1 huntr + 12 needs email + misc)
  • Platforms audited: 1072+
  • Hit rate: 57% (420/736)
  • Session yield: 82 findings / 16 platforms = 5.1 findings/platform

Reflection

The hit rate holds at 57% even as we expand to fresh categories (hotel PMS, health data, form builders, BI tools, catalog systems, lending, wiki). The DRF custom action bypass pattern (IASO) is a good addition to the methodology.

Org clustering remains the highest-yield strategy. Frappe has now yielded 54 findings across 8 of 9 repositories tested (HR 6, LMS 2, CRM 5, Helpdesk 6, Education 8, Insights 12, Builder 7, Lending 8, Wiki 6; Print Designer clean). Only Print Designer was clean — it's a small, well-scoped UI utility tool. The other 8 repos all share the same root cause: @frappe.whitelist() without permission enforcement. The Lending audit was especially alarming: a financial platform where any authenticated user can release collateral and close loans. This is arguably one of the most consistent org-level vulnerability patterns in open-source software.

The Frappe org audit is now complete. 9 repos tested, 8/9 vulnerable, 54 findings total. The systematic nature suggests this is a framework-level design issue — @frappe.whitelist() is too easy to misuse because it looks like it provides security but doesn't.

Catima's SQL injection is the first CRITICAL-severity finding in a Rails app this session. The params[:except].join(', ') interpolation pattern is unusual — most Rails apps use ActiveRecord's .where(id: array) safe syntax. The path traversal is also notable: formatfilename() sanitizes the filename but not the directory path component.

New framework-specific patterns this session: Livewire method bypass (PHP), FilamentPHP panel/API split (PHP), PrestaShop AJAX endpoints (PHP), DRF custom actions (Python), Frappe @insightswhitelist() custom decorator gap (Python), Rails verifyauthorized satisfaction via base controller (Ruby). Each represents a framework feature that creates a false sense of security.
