• CVE-2026-10701HIGH 7.5

  Firefox's text rendering engine contains a flaw in how it validates memory boundaries when processing text data. An attacker on the network can exploit this without requiring user interaction or special permissions, allowing them to read sensitive information from the browser's memory. The vulnerability affects Firefox versions prior to 151.0.3.

• CVE-2026-10702MEDIUM 4.3

  A flaw in Firefox's JavaScript Just-In-Time (JIT) compiler can cause it to miscompile code in certain circumstances. When a user visits a malicious website, the affected browser may crash or become unstable due to incorrect code generation during compilation. This is not a memory corruption issue and does not allow attackers to steal data or take control of the system, but it does impact availability and user experience.
