  "description": "The \u003Ccode\u003Ems-msdt\u003C/code\u003E, \u003Ccode\u003Esearch\u003C/code\u003E, and \u003Ccode\u003Esearch-ms\u003C/code\u003E 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.\u003Cbr\u003E*This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox \u003C 102, Firefox ESR \u003C 91.11, Thunderbird \u003C 102, and Thunderbird \u003C 91.11.",
