**Name of the Vulnerable Software and Affected Versions** Firefox versions prior to 107 Firefox ESR versions prior to 102.5 Thunderbird versions prior to 102.5 **Description** The issue is related to errors in security settings in the Service Workers service of Mozilla Firefox, Firefox ESR, and the Thunderbird email client. Exploitation of this issue may allow a remote attacker to bypass existing security restrictions. Specifically, when a ServiceWorker intercepts a request with a `FetchEvent`, the origin of the request is lost after the ServiceWorker takes ownership of it, negating SameSite cookie protections. **Recommendations** For Firefox versions prior to 107, update to version 107 or later to resolve the issue. For Firefox ESR versions prior to 102.5, update to version 102.5 or later to resolve the issue. For Thunderbird versions prior to 102.5, update to version 102.5 or later to resolve the issue.

**Name of the Vulnerable Software and Affected Versions** Google Chrome versions prior to 97.0.4692.71 **Description** The issue is related to a policy bypass in the Blink mechanism of Google Chrome, allowing a remote attacker to leak cross-origin data via a crafted HTML page. This can result in the disclosure of protected information. **Recommendations** For versions prior to 97.0.4692.71, update to version 97.0.4692.71 or later to resolve the issue. As a temporary workaround, consider restricting access to sensitive information when using Google Chrome until the update is applied.
