VCID-1q61-xygj-z3c1
|
An attacker who enumerated resources from the WebCompat extension could have obtained a persistent UUID that identified the browser, and persisted between containers and normal/private browsing mode, but not profiles.
|
CVE-2025-6425
|
|
VCID-1zvj-cyx8-vyg4
|
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. Viewing the email in HTML mode is enough to
load external content.

CVE-2025-5986
|
|
VCID-24jc-r9xj-93fs
|
A process isolation vulnerability in Firefox stemmed from improper handling of javascript: URIs, which could allow content to execute in the top-level document's process instead of the intended frame, potentially enabling a sandbox escape.
|
CVE-2025-4083
|
|
VCID-2gvb-9ecp-n3a9
|
An inconsistent comparator in xslt/txNodeSorter could have resulted in potentially exploitable out-of-bounds access. Only affected version 122 and later.
|
CVE-2025-1932
|
|
VCID-2js5-w357-qfd7
|

|
CVE-2024-10464
|
|
VCID-2paw-5vw1-jkbj
|

|
CVE-2025-26696
|
|
VCID-2st9-4ff5-kuf9
|
Insufficient escaping in the “Copy as cURL” feature could potentially be used to trick a user into executing unexpected code.

|
VCID-3p6h-zmbc-gbgq
|
Thunderbird executed javascript: URLs when used in object and embed tags.
|
CVE-2025-8029
|
|
VCID-3qsj-e421-g7a9
|
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. Although the
correct link is used on click, the misleading hover text could
trick users into downloading content from untrusted sources.
|
CVE-2025-3523
|
|
VCID-3rnm-313t-8bf8
|
The application failed to account for exceptions thrown by the `loadManifestFromFile` method during add-on signature verification. This flaw, triggered by an invalid or unsupported extension manifest, could have caused runtime errors that disrupted the signature validation process. As a result, the enforcement of signature validation for unrelated add-ons may have been bypassed. Signature validation in this context is used to ensure that third-party applications on the user's computer have not tampered with the user's extensions, limiting the impact of this issue.
|
CVE-2024-11696
|
|
VCID-456s-g2t4-uqfy
|
A crafted URL containing specific Unicode characters could have hidden the true origin of the page, resulting in a potential spoofing attack.
|
CVE-2025-3029
|
|
VCID-4g4j-e7x5-zfhs
|
When a file download is specified via the Content-Disposition header, that directive would be ignored if the file was included via a <embed> or <object> tag, potentially making a website vulnerable to a cross-site scripting attack.
|
CVE-2025-6430
|
|
VCID-52ca-d5he-sqdq
|
Enhanced Tracking Protection's Strict mode may have inadvertently allowed a CSP `frame-src` bypass and DOM-based XSS through the Google SafeFrame shim in the Web Compatibility extension. This issue could have exposed users to malicious frames masquerading as legitimate content.
|
CVE-2024-11694
|
|
VCID-66zs-8x4h-guhx
|
Thunderbird processes the X-Mozilla-External-Attachment-URL header
to handle attachments which can be hosted externally. When an
email is opened, Thunderbird accesses the specified URL to
determine file size, and navigates to it when the user clicks the
attachment. Because the URL is not validated or sanitized, it can
reference internal resources like chrome:// or SMB share file:// links,
potentially leading to hashed Windows credential leakage and opening the
door to more serious security issues.
|
CVE-2025-3522
|

VCID-6xvd-y4x1-4bh4
|
Memory safety bugs present in Firefox 134, Thunderbird 134, Firefox ESR 115.19, Firefox ESR 128.6, Thunderbird 115.19, and Thunderbird 128.6. 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.

|
CVE-2024-10458
|
|
VCID-d6uv-yc2e-pbf7
|
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.

|
CVE-2024-11699
|
|
VCID-f6fg-gxw7-4yab
|
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.

By crafting a malformed file name for an attachment in a multipart
message, an attacker can trick Thunderbird into including a
directory listing of /tmp when the message is forwarded or edited
as a new message. This vulnerability could allow attackers to
disclose sensitive information from the victim's system. This
vulnerability is not limited to Linux; similar behavior has been
observed on Windows as well.
