CVE-2021-43529 1 Mozilla 1 Thunderbird 2025-03-19 N/A 9.8 CRITICAL
Thunderbird versions prior to 91.3.0 are vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS signatures.
CVE-2024-6610 1 Mozilla 2 Firefox, Thunderbird 2025-03-18 N/A 4.3 MEDIUM

CVE-2024-9398 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-03-18 N/A 5.3 MEDIUM
By checking the result of calls to `window.open` with specifically set protocol handlers, an attacker could determine if the application which implements that protocol handler is installed. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2024-7527 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-03-18 N/A 8.8 HIGH

CVE-2024-9397 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-03-18 N/A 6.1 MEDIUM
A missing delay in directory upload UI could have made it possible for an attacker to trick a user into granting permission via clickjacking. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2024-9399 1 Mozilla 2 Firefox, Thunderbird 2025-03-14 N/A 7.5 HIGH
A website configured to initiate a specially crafted WebTransport session could crash the Firefox process leading to a denial of service condition. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2024-9394 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-03-14 N/A 7.5 HIGH
An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the `resource://devtools` origin. This could allow them to access cross-origin JSON content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Firefox ESR < 115.16, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2024-9393 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-03-14 N/A 7.5 HIGH
An attacker could, via a specially crafted multipart response, execute arbitrary JavaScript under the `resource://pdf.js` origin. This could allow them to access cross-origin PDF content. This access is limited to "same site" documents by the Site Isolation feature on desktop clients, but full cross-origin access is possible on Android versions. This vulnerability affects Firefox < 131, Firefox ESR < 128.3, Firefox ESR < 115.16, Thunderbird < 128.3, and Thunderbird < 131.
CVE-2024-4777 2 Debian, Mozilla 3 Debian Linux, Firefox, Thunderbird 2025-03-13 N/A 8.8 HIGH
Memory safety bugs present in Firefox 125, Firefox ESR 115.10, and Thunderbird 115.10. 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 affects Firefox < 126, Firefox ESR < 115.11, and Thunderbird < 115.11.
CVE-2023-4863 9 Bandisoft, Bentley, Debian and 6 more 12 Honeyview, Seequent Leapfrog, Debian Linux and 9 more 2025-03-13 N/A 8.8 HIGH
Heap buffer overflow in libwebp in Google Chrome prior to 116.0.5845.187 and libwebp 1.3.2 allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page. (Chromium security severity: Critical)
CVE-2024-6609 1 Mozilla 2 Firefox, Thunderbird 2025-03-13 N/A 8.8 HIGH
When almost out-of-memory an elliptic curve key which was never allocated could have been freed again. This vulnerability affects Firefox < 128 and Thunderbird < 128.
CVE-2025-1015 1 Mozilla 1 Thunderbird 2025-03-10 N/A 5.4 MEDIUM
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. This vulnerability affects Thunderbird < 128.7 and Thunderbird < 135.
CVE-2022-26485 1 Mozilla 4 Firefox, Firefox Esr, Firefox Focus and 1 more 2025-03-06 N/A 8.8 HIGH
