Due to a weak Content Security Policy on the /proxy/* route, an attacker can bypass the CSP of the media proxy and execute cross-site scripting when opening external images in a new tab/window. To mitigate the vulnerability, the CSP for the media proxy has been changed from default-src 'self' to default-src 'none'; form-action 'none'; sandbox;. This vulnerability is fixed in 2.2.7.","aliases":["GHSA-cq88-842x-2jhp","GO-2025-3591"],"modified":"2026-08-12T03:51:25.086825587Z","published":"2025-04-03T18:07:32.241Z","related":["openSUSE-SU-2025:14982-1"],"database_specific":{"cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/31xxx/CVE-2025-31483.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/31xxx/CVE-2025-31483.json"},{"type":"ADVISORY","url":"https://github.com/miniflux/v2/security/advisories/GHSA-cq88-842x-2jhp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-31483"},{"type":"FIX","url":"https://github.com/miniflux/v2/commit/cb695e653a08af4cabcb277c271ce74bd0c746e6"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/miniflux/v2","events":[{"introduced":"0"},{"fixed":"cb695e653a08af4cabcb277c271ce74bd0c746e6"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.2.7"}]}}],"versions":["2.2.6","2.2.5","2.2.4","v2.2.3","2.2.3","2.2.2","2.2.1","v2.2.0","2.2.0","2.1.4","2.1.3","v2.1.2","2.1.2","v2.1.1","2.1.1","2.1.0","v2.0.51","2.0.51","2.0.50","v2.0.49","2.0.49","2.0.48","v2.0.48","v2.0.47","2.0.47","v2.0.46","v1.0.46","2.0.46","2.0.45","2.0.44","2.0.43","2.0.42","2.0.41","2.0.40","2.0.39","2.0.38","2.0.37","2.0.36","2.0.35","2.0.34","2.0.33","2.0.32","2.0.31","2.0.30","2.0.29","2.0.28","2.0.27","2.0.26","2.0.25","2.0.24","2.0.23","2.0.22","2.0.21","2.0.20","2.0.19","2.0.18","2.0.17","2.0.16","2.0.15","2.0.14","2.0.13","2.0.12","2.0.11","2.0.10","2.0.9","2.0.8","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0.2","2.0.1","2.0.0","2.0.0-rc1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-31483.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:L/VI:L/VA:N/SC:L/SI:L/SA:N"}]}
