CVE-2025-68402

FreshRSS has an authentication bypass due to truncated bcrypt hash [edge branch]

Published Mar 9, 2026 CVSS 4.0 · 8.2 High EPSS < 1% KEV · Not listed
Description
FreshRSS is a free, self-hostable RSS aggregator. From 57e1a37 - 00f2f04, the lengths of the nonce was changed from 40 chars to 64. password_verify() is currently being called with a constructed string (SHA-256 nonce + part of a bcrypt hash) instead of the raw user password. Due to bcrypt’s 72-byte input truncation, this causes password verification to succeed even when the user enters an incorrect password. This vulnerability is fixed in 1.27.2-dev (476e57b). The issue was only present in the edge branch and never in a stable release.
