{"id":"CVE-2025-46339","summary":"FreshRSS vulnerable to favicon cache poisoning via proxy","details":"FreshRSS is a self-hosted RSS feed aggregator. Prior to version 1.26.2, it's possible to poison feed favicons by adding a given URL as a feed with the proxy set to an attacker-controlled one and disabled SSL verifying. The favicon hash is computed by hashing the feed URL and the salt, whilst not including the following variables: proxy address, proxy protocol, and whether SSL should be verified. Therefore it's possible to poison a favicon of a given feed by simply intercepting the response of the feed, and changing the website URL to one where a threat actor controls the feed favicon. Feed favicons can be replaced for all users by anyone. Version 1.26.2 fixes the issue.","aliases":["GHSA-8f79-3q3w-43c4"],"modified":"2026-08-12T03:51:22.699263134Z","published":"2025-06-04T20:04:54.504Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-349"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/46xxx/CVE-2025-46339.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/46xxx/CVE-2025-46339.json"},{"type":"ADVISORY","url":"https://github.com/FreshRSS/FreshRSS/security/advisories/GHSA-8f79-3q3w-43c4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-46339"},{"type":"FIX","url":"https://github.com/FreshRSS/FreshRSS/commit/3776e1e48f33e80eb4b674bb64b419caf3b5a4e2"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/freshrss/freshrss","events":[{"introduced":"0"},{"fixed":"4c5e8e77b3bbf5d72f801902198bcb967e5a0358"},{"fixed":"3776e1e48f33e80eb4b674bb64b419caf3b5a4e2"}],"database_specific":{"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:freshrss:freshrss:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.26.2"}]}}],"versions":["1.26.1","1.26.0","1.25.0","1.24.3","1.24.2","1.24.1","1.24.0","1.23.1","1.23.0","1.22.1","1.22.0","1.21.0","1.20.1","1.20.0","1.19.2","1.19.1","1.19.0","1.18.1","1.18.0","1.17.0","1.16.2","1.16.1","1.16.0","1.15.2","1.15.1","1.15.0","1.14.3","1.14.2","1.14.1","1.14.0","1.13.1","1.13.0","1.12.0","1.11.2","1.11.1","1.11.0","1.10.2","1.10.1","1.10.0","1.9.0","1.8.0","1.6.1","1.7.0","1.6.3","1.6.2","0.7.1","1.6.0","1.5.0","1.4.0","1.2.0","1.0.0","0.8.1","0.8.0","0.7.0","0.6.1","0.6.0","0.5.0","0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-46339.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
