CVE-2025-31483

MEDIUM

Miniflux v2 < 2.2.7 - Cross-Site Scripting via Media Proxy CSP Bypass

Title source: llm
STIX 2.1

Description

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.
