{"id":"CVE-2025-68402","state":"PUBLISHED","title":"FreshRSS has an authentication bypass due to truncated bcrypt hash [edge branch]","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.","publishedAt":"2026-03-09T19:41:57.974Z","updatedAt":"2026-03-09T20:44:25.146Z","severity":{"score":8.2,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["FreshRSS FreshRSS"],"affected":[{"vendor":"FreshRSS","product":"FreshRSS","versions":[{"version":"< 476e57b04646416e24e24c56133c9fadf9e52b95","status":"affected"}]}],"references":["https://github.com/FreshRSS/FreshRSS/security/advisories/GHSA-pcq9-mq6m-mvmp","https://github.com/FreshRSS/FreshRSS/pull/8061","https://github.com/FreshRSS/FreshRSS/pull/8320","https://github.com/FreshRSS/FreshRSS/commit/476e57b04646416e24e24c56133c9fadf9e52b95"],"weaknesses":["CWE-287"],"ingestedAt":"2026-10-29T20:09:56.034Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/68xxx/CVE-2025-68402.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2025-68402","state":"PUBLISHED","datePublished":"2026-03-09T19:41:57.974Z","dateUpdated":"2026-03-09T20:44:25.146Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-12-16T21:59:48.534Z"},"containers":{"cna":{"title":"FreshRSS has an authentication bypass due to truncated bcrypt hash [edge branch]","descriptions":[{"lang":"en","value":"FreshRSS is a free, self-hostable RSS aggregator.
