CVE-2024-11700Public exploitNetwork attack vector

External application launch via tapjacked intent prompt

Published Nov 26, 2024 · Updated Jan 6, 2025

Tapjacking in Mozilla Firefox and Thunderbird before 133 allows remote attackers to trick users into approving Android app launches. The Android intent-confirmation prompt enabled its Allow control immediately, so rapid taps aimed at an underlying page could activate the newly displayed approval button. Successful exploitation requires a user to visit a malicious website and tap repeatedly; approval launches an external application whose own flaws can then be exposed.
