Vulnerability Summary Fixed by
VCID-7q66-66b2-kucc
Aliases:
CVE-2025-5266
Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. There are no reported fixed by versions.
VCID-7v6j-9uuc-qkc8
Aliases:
CVE-2025-4919
An attacker was able to perform an out-of-bounds read or write on a JavaScript object by confusing array index sizes. There are no reported fixed by versions.
VCID-8hm6-nz5h-yfcm
Aliases:
CVE-2025-4918

VCID-98mt-7srw-qfh4
Aliases:
CVE-2025-5283
A vulnerability has been discovered in libvpx, which could lead to execution of arbitrary code. There are no reported fixed by versions.
VCID-a8vw-n16x-duee
Aliases:
CVE-2025-5264
Due to insufficient escaping of the newline character in the “Copy as cURL” feature, an attacker could trick a user into using this command, potentially leading to local code execution on the user's system. There are no reported fixed by versions.
VCID-dcjm-7xcr-ayew
Aliases:
CVE-2025-5268
Memory safety bugs present in Firefox 138, Thunderbird 138, Firefox ESR 128.10, and Thunderbird 128.10. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. There are no reported fixed by versions.
VCID-n2hq-1ck4-ayhp
Aliases:
CVE-2025-5263
Error handling for script execution was incorrectly isolated from web content, which could have allowed cross-origin leak attacks. There are no reported fixed by versions.
VCID-n3rs-11fq-wqc4
Aliases:
CVE-2025-3875
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. There are no reported fixed by versions.
VCID-pneu-6c1f-zkfa
Aliases:
CVE-2025-3909
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. There are no reported fixed by versions.
VCID-rkj9-dd18-xka9
Aliases:
CVE-2025-5267
A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. There are no reported fixed by versions.
VCID-uy2g-rmuh-pkbe
Aliases:
CVE-2025-3932
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. There are no reported fixed by versions.
VCID-y45y-r8h7-6yez
Aliases:
CVE-2025-5269
Memory safety bug present in Firefox ESR 128.10, and Thunderbird 128.10. This bug showed evidence of memory corruption and we presume that with enough effort this could have been exploited to run arbitrary code. There are no reported fixed by versions.
