a12nserver vulnerable to potential SQL Injections via Knex dependency
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
@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

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, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
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 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-crhg-xgrg-vvcc can be triaged on real exposure rather than presence alone.
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.
