No CVSS score has been assigned to GHSA-92hr-gmr6-h8cp yet. Review the advisory details and affected package list to assess your exposure.

Which packages are affected by GHSA-92hr-gmr6-h8cp?

GHSA-92hr-gmr6-h8cp affects the following packages: ep_etherpad-lite (npm). Ecosystems affected: npm.

How do I fix GHSA-92hr-gmr6-h8cp?

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.

How do I detect GHSA-92hr-gmr6-h8cp in my npm dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for ep_etherpad-lite, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-92hr-gmr6-h8cp if there is no patch (or I can't update yet)?

Resolve every user-supplied path to its canonical form and reject anything that escapes the intended directory, and run the component under an account that has no read or write access outside the directory it legitimately serves.

Is GHSA-92hr-gmr6-h8cp actively exploited in the wild?

No public exploit code has been indexed for GHSA-92hr-gmr6-h8cp yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

When was GHSA-92hr-gmr6-h8cp published, and has it been updated?

GHSA-92hr-gmr6-h8cp was published on August 17, 2026 and was last updated on August 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

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 use crypto.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.timingSafeEqual plus 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/2 merged all request headers into the API field set. Now forwards only authorization, matching the openapi.ts handler.
Pad-creation side effect: API.appendChatMessage could create arbitrary pads (missing getPadSafe). Now requires the pad to exist.
Error info disclosure (CWE-209): the admin file server echoed filesystem error detail; now returns a generic message.
