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. Although the correct link is used on click, the misleading hover text could trick users into downloading content from untrusted sources. This vulnerability was fixed in Thunderbird 137.0.2 and Thunderbird 128.9.2.
CVE-2025-4083 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 9.1 Critical
A process isolation vulnerability in Thunderbird 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. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Firefox ESR 115.23, Thunderbird 138, and Thunderbird 128.10.
CVE-2025-4087 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 4.8 Medium
A vulnerability was identified in Thunderbird where XPath parsing could trigger undefined behavior due to missing null checks during attribute access. This could lead to out-of-bounds read access and potentially, memory corruption. This vulnerability was fixed in Firefox 138, Firefox ESR 128.10, Thunderbird 138, and Thunderbird 128.10.
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-2025-3875 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.
CVE-2025-4918 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 9.8 Critical
An attacker was able to perform an out-of-bounds read or write on a JavaScript `Promise` object. This vulnerability was fixed in Firefox 138.0.4, Firefox ESR 128.10.1, Firefox ESR 115.23.1, Thunderbird 128.10.2, and Thunderbird 138.0.2.
CVE-2025-4919 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.8 High
An attacker was able to perform an out-of-bounds read or write on a JavaScript object by confusing array index sizes. This vulnerability was fixed in Firefox 138.0.4, Firefox ESR 128.10.1, Firefox ESR 115.23.1, Thunderbird 128.10.2, and Thunderbird 138.0.2.
CVE-2025-5266 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2026-04-20 4.3 Medium
Script elements loading cross-origin resources generated load and error events which leaked information enabling XS-Leaks attacks. This vulnerability was fixed in Firefox 139, Firefox ESR 128.11, Thunderbird 139, and Thunderbird 128.11.
CVE-2025-5267 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Rhel Aus and 4 more 2026-04-20 5.4 Medium
A clickjacking vulnerability could have been used to trick a user into leaking saved payment card details to a malicious page. This vulnerability was fixed in Firefox 139, Firefox ESR 128.11, Thunderbird 139, and Thunderbird 128.11.
CVE-2025-5268 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.1 High
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. This vulnerability was fixed in Firefox 139, Firefox ESR 128.11, Thunderbird 139, and Thunderbird 128.11.
CVE-2025-5269 2 Mozilla, Redhat 8 Firefox, Thunderbird, Enterprise Linux and 5 more 2026-04-20 8.1 High
Memory safety bug present in Firefox ESR 128.10, 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. This vulnerability was fixed in Firefox ESR 128.11 and Thunderbird 128.11.
CVE-2025-5986 2 Mozilla, Redhat 6 Thunderbird, Enterprise Linux, Rhel Aus and 3 more 2026-04-20 6.5 Medium
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. This vulnerability was fixed in Thunderbird 128.11.1 and Thunderbird 139.0.2.
CVE-2026-40917 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-04-20 5 Medium
A flaw was found in GIMP. This vulnerability, a heap buffer over-read in the `icns_slurp()` function, occurs when processing specially crafted ICNS image files. An attacker could provide a malicious ICNS file, potentially leading to application crashes or information disclosure on systems that process such files.
CVE-2026-40918 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-04-20 5.5 Medium
A flaw was found in GIMP. Processing a specially crafted PVR image file with large dimensions can lead to a denial of service (DoS). This occurs due to a stack-based buffer overflow and an out-of-bounds read in the PVR image loader, causing the application to crash. Systems that process untrusted PVR image files are affected.
CVE-2026-40916 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-04-20 5 Medium
A flaw was found in GIMP. A stack buffer overflow vulnerability in the TIM image loader's 4BPP decoding path allows a local user to cause a Denial of Service (DoS). By opening a specially crafted TIM image file, the application crashes due to an unconditional overflow when writing to a variable-length array.
CVE-2026-40915 2 Gimp, Redhat 2 Gimp, Enterprise Linux 2026-04-20 5.5 Medium
A flaw was found in GIMP. A remote attacker could exploit an integer overflow vulnerability in the FITS image loader by providing a specially crafted FITS file. This integer overflow leads to a zero-byte memory allocation, which is then subjected to a heap buffer overflow when processing pixel data. Successful exploitation could result in a denial of service (DoS) or potentially arbitrary code execution.
CVE-2025-6430 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2026-04-20 6.1 Medium
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. This vulnerability was fixed in Firefox 140, Firefox ESR 128.12, Thunderbird 140, and Thunderbird 128.12.
CVE-2025-8028 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2026-04-20 9.8 Critical
On arm64, a WASM `br_table` instruction with a lot of entries could lead to the label being too far from the instruction causing truncation and incorrect computation of the branch address. This vulnerability was fixed in Firefox 141, Firefox ESR 115.26, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1.
CVE-2025-8029 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2026-04-20 8.1 High
Thunderbird executed `javascript:` URLs when used in `object` and `embed` tags. This vulnerability was fixed in Firefox 141, Firefox ESR 128.13, Firefox ESR 140.1, Thunderbird 141, Thunderbird 128.13, and Thunderbird 140.1.
