A memory-safety flaw in Firefox's Audio/Video component - a classic out-of-bounds write/overflow class issue caused by incorrect boundary checking - lets an attacker who convinces a user to open a crafted page or media file corrupt memory and escalate privileges to the level the browser process runs at. The issue affects Firefox branches prior to 156 and Firefox ESR prior to 153.3, and is reachable without authentication but requires user interaction. Mozilla has released fixed builds (Firefox 156, Firefox ESR 153.3) via advisories MFSA2026-90 and MFSA2026-93; there is no public exploit identified at time of analysis and CISA SSVC records exploitation as 'none'.
