Summary
yelp security update
Details

Yelp is the help viewer in GNOME. It natively views Mallard, DocBook, man, info, and HTML documents. It can locate documents according to the freedesktop.org help system specification.

Security Fix(es):

A flaw was found in Yelp due to an overly permissive Content Security Policy (CSP) implementation provided by yelp-xsl. A malicious Flatpak application can open crafted help content through the OpenURI portal. By embedding an untrusted CSS stylesheet within a structured SVG document, attacker-controlled content can bypass Flatpak's intended sandbox isolation, allowing Yelp to evaluate local XML inclusions and disclose arbitrary user-readable host files through remote CSS resource requests. This may result in the unauthorized disclosure of sensitive information.(CVE-2026-13601)
