GHSA-92hr-gmr6-h8cp
Fix: ether/etherpad#7906GHSA-92hr-gmr6-h8cp is a security vulnerability in ep_etherpad-lite. O3 Security confirms whether GHSA-92hr-gmr6-h8cp is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Etherpad addressed weak token RNG, login timing, plugin path handling, API request handling
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.
ep_etherpad-litenpmDescription
Fix: PR #7906 (ether/etherpad). A set of medium/low hardening fixes:
- Weak RNG for tokens (CWE-330): author/session/readonly IDs were generated with
Math.random()(client and server). Now usecrypto.getRandomValues. - Login timing / no failure delay (CWE-208/CWE-307): the OIDC interaction login used a non-constant-time password compare with no failure delay. Now uses
crypto.timingSafeEqualplus a uniform failure delay; user lookup is own-property only. - Plugin dependency path handling (CWE-22): plugin dependency names from package.json were used to build filesystem paths without validation (admin-gated install). Now validated against the npm name grammar.
- API parameter pollution (CWE-235):
/api/2merged all request headers into the API field set. Now forwards onlyauthorization, matching the openapi.ts handler. - Pad-creation side effect:
API.appendChatMessagecould create arbitrary pads (missinggetPadSafe). Now requires the pad to exist. - Error info disclosure (CWE-209): the admin file server echoed filesystem error detail; now returns a generic message.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ep_etherpad-lite. 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 ep_etherpad-lite to 3.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-92hr-gmr6-h8cp 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-92hr-gmr6-h8cp 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-92hr-gmr6-h8cp. 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-92hr-gmr6-h8cp in your dependencies?
O3 detects GHSA-92hr-gmr6-h8cp across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
