CVE-2025-1015 1 Mozilla 1 Thunderbird 2025-03-10 N/A 5.4 MEDIUM
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 affects Thunderbird < 128.7 and Thunderbird < 135.
