27 May 2025 — Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. This vulnerability affects Firefox < 139, Firefox ESR < 115.24, and Firefox ESR < 128.11. A flaw was found in Firefox. The Mozilla Foundation's Security Advisory describes the following issue: Error handling for script execution is incorrectly isolated from web content, which could allow cross-origin leak attacks.

CVSS: 7.8EPSS: 0%CPEs: 23EXPL: 0CVE-2025-3932 – thunderbird: Tracking Links in Attachments Bypassed Remote Content Blocking
https://notcve.org/view.php?id=CVE-2025-3932
14 May 2025 — It was possible to craft an email that showed a tracking link as an attachment. If the user attempted to open the attachment, Thunderbird automatically accessed the link. The configuration to block remote content did not prevent that. Thunderbird has been fixed to no longer allow access to web pages listed in the X-Mozilla-External-Attachment-URL header of an email. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1. • https://bugzilla.mozilla.org/show_bug.cgi?id=1960412 • CWE-288: Authentication Bypass Using an Alternate Path or Channel •

https://notcve.org/view.php?id=CVE-2025-3909
14 May 2025 — Thunderbird's handling of the X-Mozilla-External-Attachment-URL header can be exploited to execute JavaScript in the file:/// context. By crafting a nested email attachment (message/rfc822) and setting its content type to application/pdf, Thunderbird may incorrectly render it as HTML when opened, allowing the embedded JavaScript to run without requiring a file download. This behavior relies on Thunderbird auto-saving the attachment to /tmp and linking to it via the file:/// protocol, potentially enabling Ja... • https://bugzilla.mozilla.org/show_bug.cgi?id=1958376 • CWE-290: Authentication Bypass by Spoofing •

https://notcve.org/view.php?id=CVE-2025-3877
14 May 2025 — A crafted HTML email using mailbox:/// links can trigger automatic, unsolicited downloads of .pdf files to the user's desktop or home directory without prompting, even if auto-saving is disabled. This behavior can be abused to fill the disk with garbage data (e.g. using /dev/urandom on Linux) or to leak Windows credentials via SMB links when the email is viewed in HTML mode. While user interaction is required to download the .pdf file, visual obfuscation can conceal the download trigger.

https://notcve.org/view.php?id=CVE-2025-3875
14 May 2025 — 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 spoofed@example.com as the actual address. This vulnerability affects Thunderbird < 128.10.1 and Thunderbird < 138.0.1.

29 Apr 2025 — Mozilla Firefox's update mechanism allowed a medium-integrity user process to interfere with the SYSTEM-level updater by manipulating the file-locking behavior. By injecting code into the user-privileged process, an attacker could bypass intended access controls, allowing SYSTEM-level file operations on paths controlled by a non-privileged user and enabling privilege escalation.
