CVE-2026-40263

Note Mark is an open-source note-taking application. In versions 0.19.1 and prior, the login endpoint performs bcrypt password verification only when the supplied username exists, returning immediately for nonexistent usernames. This timing discrepancy allows unauthenticated attackers to enumerat...

BIT-AUTHENTIK-2024-52307 authentik allows a timing attack due to missing constant time comparison for metrics view

authentik is an open-source identity provider. Due to the usage of a non-constant time comparison for the /-/metrics/ endpoint it was possible to brute-force the SECRETKEY, which is used to authenticate the endpoint. The /-/metrics/ endpoint returns Prometheus metrics and is not intended to be...

GHSA-WQQ3-WFMP-V85G Mojic: Observable Timing Discrepancy in HMAC Verification

Summary The CipherEngine in Mojic v2.1.3 uses a standard equality operator !== to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy CWE-208, allowing a potential attacker to bypass the file integrity check via a timing attack. Details...
