CVE-2026-107677: Ffmpeg

Medium severity, CVSS 4.7. EPSS: 0.1% chance of exploitation in the next 30 days.

FFmpeg through 9.0.2 contains a denial of service vulnerability in the DASH demuxer that allows attackers to trigger an infinite loop by supplying an empty SegmentTemplate media URL. Attackers can craft an .mpd manifest declaring SegmentTemplate media="" so get_current_fragment() calls av_strireplace() with an empty search string, consuming CPU indefinitely.

Affected products

• Ffmpeg Ffmpeg: up to and including 9.0.2
