An attacker was able to achieve code execution in the content process by exploiting a use-after-free in Animation timelines.
Firefox, Firefox ESR and Thunderbird builds before the fixed releases are exposed. Firefox 131.0.2, Firefox ESR 128.3.1 and 115.16.1, and Thunderbird 131.0.1, 128.3.1 and 115.16.0 contain the fix. No vendor severity is given; CVSS is 9.8.
