CVE-2025-3875

CVE-2025-3875 · Sender Spoofing via Malformed From Header in Thunderbird

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Thunderbird parses addresses in a way that can allow sender spoofing in case the server allows an invalid From address to be used. For example, if the From header contains an (invalid) value "Spoofed Name ", Thunderbird treats [email protected] as the actual address. This vulnerability was fixed in Thunderbird 128.10.1 and Thunderbird 138.0.1.
