Description
The WebChannel API, which is used to transport various information across processes, did not check the sending principal but rather accepted the principal being sent. This could have led to privilege escalation attacks. This vulnerability was fixed in Firefox 134, Firefox ESR 128.6, Thunderbird 134, and Thunderbird 128.6.
Affected configurations
• mozilla firefox (< 128.6.0)
• mozilla firefox (< 134.0)
• mozilla thunderbird (< 128.6.0)
• mozilla thunderbird (>= 129.0 < 134.0)
