Mozilla Thunderbird and 4 others: URL Redirection to Untrusted Site ('Open Redirect')
CVE-2022-34478 is fixed in 3 products on 1 platform, first by Mozilla Firefox ESR (en-US) 102.0, released June 23, 2022. It is not reported as exploited. Patch Radar priority: Routine.
The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them.<br>*This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
