EUVD-2026-22872

Covert timing channel vulnerability in Legion of the Bouncy Castle Inc. BC-JAVA core on all core modules. Non-constant time comparisons risk private key leakage in FrodoKEM. This issue affects BC-JAVA: from 2.17.3 before 1.84...

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...
