CVE-2025-31483 (opens in a new tab)How to fix?
Upgrade Debian:unstable miniflux to version 2.2.12-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream miniflux package and not the miniflux package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
