How do I fix CVE-2026-53926?

Update nocodb to 2026.05.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2026-53926 is resolved across your whole dependency graph.

How do I detect CVE-2026-53926 in my npm dependencies?

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

How do I mitigate CVE-2026-53926 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is CVE-2026-53926 actively exploited in the wild?

Description

Summary

OAuth access and refresh tokens were not revoked when the user changed, reset, or recovered their password, leaving an attacker-issued OAuth grant valid after the user believed they had locked the attacker out.

Details

revokeAllOAuthTokensByUser in the users service was an empty stub being called from passwordChange, passwordForgot, and passwordReset. It now delegates to OAuthToken.revokeAllByUser(userId), which deletes the rows and invalidates the related auth caches. All three reset/recovery flows now consistently revoke refresh tokens (GHSA-r989-7g3j-wjhw), OAuth tokens (this advisory), and rotate token_version.

Impact

Persistent unauthorized access through previously issued OAuth tokens after a documented security event (password change, forgot, or reset).
