What is CVE-2025-31483?

Miniflux, a popular feed reader, has a vulnerability due to a weak Content Security Policy (CSP) on the /proxy/* route. This weakness allows attackers to bypass the CSP of the media proxy, potentially executing cross-site scripting (XSS) attacks when external images are opened in a new tab or window. The security measures have since been updated in version 2.2.7, changing the CSP settings to enhance security and mitigate the risk.

Affected Version(s)

v2 < 2.2.7
