Summary

Mozilla Firefox before 20.0 on Android uses world-writable and world-readable permissions for the app_tmp installation directory in the local filesystem, which allows attackers to modify add-ons before installation via an application that leverages the time window during which app_tmp is used.

Exploit prediction

0.99% chance of exploitation in the next 30 days, higher than 62% of all scored CVEs (FIRST EPSS, 2026-11-09).
