A vulnerability in Firefox and Thunderbird prior to versions Firefox 144, Firefox ESR 115.29, Firefox ESR 140.4, Thunderbird 144, and Thunderbird ESR 140.4 allows a compromised web process to use malicious IPC messages to cause the privileged browser process to leak blocks of its memory. This cross-process information leak could expose sensitive data. The issue is part of a set of high-impact security vulnerabilities fixed in these releases.
