CVE-2024-11702

Clipboard disclosure via unprotected private-mode copying

Published Nov 26, 2024 · Updated Nov 27, 2024

Clipboard information disclosure in Mozilla Firefox and Thunderbird before 133 allows attackers to read private-tab data on Android. GeckoView failed to apply Android's sensitive-clipboard protections when private-browsing content was copied, leaving that content visible in clipboard history. Exposure requires a user to copy sensitive content and clipboard history or cloud synchronization to retain it; the reported consequence is read-only disclosure.
