Vulnerability description
DayBreach CVE AI Research
CVE-2026-54418 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Leantime through 3.6.2 exposes the JSON-RPC methods leantime.rpc.TwoFA.TwoFA.getSetupData, saveSecret, verifyAndEnable, and disable2FA, which act on a caller-supplied userId parameter with no ownership check, session pinning, or permission-attribute gate (unlike other RPC-exposed methods in the same dispatcher).
