{"id":"UBUNTU-CVE-2025-31483","details":"Miniflux is a feed reader. 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.","modified":"2026-05-20T16:07:54.888447161Z","published":"2025-04-03T18:15:00Z","upstream":["CVE-2025-31483"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2025-31483"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2025-31483"},{"type":"REPORT","url":"https://github.com/miniflux/v2/commit/cb695e653a08af4cabcb277c271ce74bd0c746e6"},{"type":"REPORT","url":"https://github.com/miniflux/v2/security/advisories/GHSA-cq88-842x-2jhp"}],"affected":[{"package":{"name":"miniflux","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/miniflux?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.0.51-1","2.0.51-2","2.0.51-2ubuntu0.1","2.0.51-2ubuntu0.2","2.0.51-2ubuntu0.2+esm1","2.0.51-2ubuntu0.3","2.0.51-2ubuntu0.3+esm1","2.0.51-2ubuntu0.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.0.51-2ubuntu0.3+esm2","binary_name":"miniflux"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-31483.json"}},{"package":{"name":"miniflux","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/miniflux?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.6-1","2.2.6-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2.6-2","binary_name":"miniflux"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-31483.json"}},{"package":{"name":"miniflux","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/miniflux?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.2.6-2","2.2.13-1","2.2.16-2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.2.16-2","binary_name":"miniflux"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2025/UBUNTU-CVE-2025-31483.json"}}],"schema_version":"1.7.5","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"},{"type":"Ubuntu","score":"medium"}]}
