Descriptions

When a ServiceWorker intercepted a request with <code>FetchEvent</code>, the origin of the request was lost after the ServiceWorker took ownership of it. This had the effect of negating SameSite cookie protections. This was addressed in the spec and then in browsers. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.

Cuando un ServiceWorker interceptó una solicitud con <code>FetchEvent</code>, el origen de la solicitud se perdió después de que ServiceWorker tomó posesión de ella. Esto tuvo el efecto de anular las protecciones de cookies de SameSite. Esto se solucionó en la especificación y luego en los navegadores. Esta vulnerabilidad afecta a Firefox ESR < 102,5, Thunderbird < 102.5 y Firefox < 107.

The Mozilla Foundation Security Advisory describes this flaw as: When a ServiceWorker intercepted a request with FetchEvent, the origin of the request was lost after the ServiceWorker took ownership of it. This had the effect of negating SameSite cookie protections. This was addressed in the spec and then in browsers.

Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code.
