This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.

MEDIUM 6.5EPSS 0.74%

Does this matter?

Lower severity and a low EPSS score (0.74%). Track it; it rarely justifies an emergency change on its own.

Description

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.
