@curveball/a12n-servernpmDescription
Impact
Users of a12nserver that use MySQL might be vulnerable to SQL injection bugs.
If you use a12nserver and MySQL, update as soon as possible. This SQL injection bug might let an attacker obtain OAuth2 Access Tokens for users unrelated to those that permitted OAuth2 clients.
Patches
The knex dependency has been updated to 2.4.0 in a12nserver 0.23.0
Workarounds
No further workarounds

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @curveball/a12n-server. 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 @curveball/a12n-server to 0.23.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-crhg-xgrg-vvcc 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-crhg-xgrg-vvcc 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-crhg-xgrg-vvcc. 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-crhg-xgrg-vvcc in your dependencies?
O3 detects GHSA-crhg-xgrg-vvcc across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
