HIGHExposure of Sensitive Information to an Unauthorized Actor in Doorkeeper

Description
Impact
Information disclosure vulnerability. Allows an attacker to see all Doorkeeper::Application model attribute values (including secrets) using authorized applications controller if it's enabled (GET /oauth/authorized_applications.json).
Patches
These versions have the fix:
- 5.0.3
- 5.1.1
- 5.2.5
- 5.3.2
Workarounds
Patch Doorkeeper::Application model #as_json(options = {}) method and define only those attributes you want to expose.
Additional recommended hardening is to enable application secrets hashing (guide), available since Doorkeeper 5.1. This would render the exposed secret useless.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for doorkeeper. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update doorkeeper to 5.0.3 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-j7vx-8mqj-cqp9 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 pinpoints whether GHSA-j7vx-8mqj-cqp9 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-j7vx-8mqj-cqp9. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-j7vx-8mqj-cqp9 in your dependencies?
O3 detects GHSA-j7vx-8mqj-cqp9 across RubyGems dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
