CVE-2024-5689Public exploitNetwork attack vector

Phishing redirects via overlaid Screenshots button

Published Jun 11, 2024 · Updated Oct 28, 2024

UI spoofing in Mozilla Firefox before 127 allows remote attackers to redirect screenshot takers to a phishing page through Firefox Screenshots. The legacy Screenshots implementation injects overlay controls into page content, allowing site elements to cover the saved-shots button and replace the navigation target. Exploitation requires a person to take a screenshot and click the overlaid button; the demonstrated consequence is redirection to an attacker-controlled replica rather than browser compromise.
