While sanitizing inline subtitle markup, the parser repeatedly searches the remaining text with unanchored regular expressions. A crafted subtitle cue with a long line of unmatched markup-like text can force quadratic CPU use and make a GStreamer-based application unresponsive.","cvssScore":6.5,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","cwes":["CWE-1333"],"vendors":[],"products":[],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-125040","tags":[]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2569124","tags":[]},{"url":"https://gstreamer.freedesktop.org/security/sa-2026-0023.html","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
