AI-suggested
European organizations should prioritize updating all affected Mozilla products to the latest patched versions: Firefox 113 or later, Firefox ESR 102.11 or later, and Thunderbird 102.11 or later. Beyond patching, organizations should implement strict browser usage policies that restrict the granting of sensitive permissions unless explicitly authorized by IT security teams. User awareness training should emphasize the risks of clicking on unexpected permission prompts and educate users on recognizing potential clickjacking attempts. Deploying browser security extensions or enterprise policies that limit or control permission requests can further reduce risk. Network-level protections such as web filtering to block malicious sites known for clickjacking attacks can also be effective. For high-risk environments, consider disabling or restricting use of browser features that require sensitive permissions unless absolutely necessary. Regular security audits and monitoring for unusual permission grants or browser behavior can help detect exploitation attempts early.
Description
A missing delay in popup notifications could have made it possible for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 113, Firefox ESR < 102.11, and Thunderbird < 102.11.
