AI-analyzed exploit summary This PoC generates a malicious vCard file that exploits CVE-2025-1015 in Thunderbird's address book. The vCard contains a base64-encoded HTML payload that, when clicked, executes arbitrary JavaScript in the context of Thunderbird's internal browser.
Description
The Thunderbird Address Book URI fields contained unsanitized links. This could be used by an attacker to create and export an address book containing a malicious payload in a field. For example, in the “Other” field of the Instant Messaging section. If another user imported the address book, clicking on the link could result in opening a web page inside Thunderbird, and that page could execute (unprivileged) JavaScript. This vulnerability was fixed in Thunderbird 128.7 and Thunderbird 135.
