Detailsinfo

A vulnerability classified as problematic was found in Mozilla Thunderbird (Mail Client Software) (the affected version is unknown). This vulnerability affects the function fetch. The manipulation with an unknown input leads to a cross site scripting vulnerability. The CWE definition for the vulnerability is CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. As an impact it is known to affect integrity. CVE summarizes:

Cross-Site Tracing occurs when a server will echo a request back via the Trace method, allowing an XSS attack to access to authorization headers and cookies inaccessible to JavaScript (such as cookies protected by HTTPOnly). To mitigate this attack, browsers placed limits on <code>fetch()</code> and XMLHttpRequest; however some webservers have implemented non-standard headers such as <code>X-Http-Method-Override</code> that override the HTTP method, and made this attack possible again. Thunderbird has applied the same mitigations to the use of this and similar headers. This vulnerability affects Firefox ESR < 102.5, Thunderbird < 102.5, and Firefox < 107.
