Description

A process isolation vulnerability in Thunderbird stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Firefox ESR 115.23, Thunderbird 138, and Thunderbird 128.10.

• mozilla firefox (< 115.23) • mozilla firefox (< 138.0) • mozilla firefox (>= 128.0 < 128.10) • mozilla thunderbird (< 128.10.0) • mozilla thunderbird (< 138.0)
