| CVE-2025-3523 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2026-04-20 | 6.4 Medium |
| When an email contains multiple attachments with external links via the X-Mozilla-External-Attachment-URL header, only the last link is shown when hovering over any attachment.

| CVE-2025-4093 | 2 Mozilla, Redhat | 8 Firefox, Thunderbird, Enterprise Linux and 5 more | 2026-04-20 | 8.1 High |
| Memory safety bug present in Firefox ESR 128.9, and Thunderbird 128.9. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox ESR 128.10 and Thunderbird 128.10. | ||||
| CVE-2025-3859 | 1 Mozilla | 1 Firefox Focus | 2026-04-20 | 4.3 Medium |
| Websites directing users to long URLs that caused eliding to occur in the location view could leverage the truncating behavior to potentially trick users into thinking they were on a different webpage. This vulnerability was fixed in Focus 138. | ||||
| CVE-2025-3875 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2026-04-20 | 7.5 High |
| 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 was fixed in Thunderbird 128.10.1 and Thunderbird 138.0.1. | ||||
| CVE-2025-3909 | 2 Mozilla, Redhat | 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more | 2026-04-20 | 8.1 High |
| 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 JavaScript execution as part of the HTML. This vulnerability was fixed in Thunderbird 128.10.1 and Thunderbird 138.0.1. | ||||
