CVE-2026-118178 1 Mozilla 1 Thunderbird 2026-10-27 N/A
A remote RSS feed could use the itunes:new-feed-url or newLocation element to permanently change its stored subscription URL to a file: URL. Thunderbird then read that location on every feed update. This allowed a malicious feed, or an attacker able to modify a feed delivered over HTTP, to make Thunderbird read local files and, on Windows, connect to an attacker-controlled network share, which could leak the user's NTLM credentials. The NTLM credential leak only affects Thunderbird on Windows. Other operating systems are affected by the local file read only. This vulnerability was fixed in Thunderbird 159 and Thunderbird 153.6.
CVE-2026-117860 1 Mozilla 2 Firefox, Thunderbird 2026-10-27 N/A
Same-origin policy bypass in the DOM: Navigation component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6.

CVE-2026-117917 1 Mozilla 2 Firefox, Thunderbird 2026-10-27 N/A
Invalid pointer in the Graphics: WebRender component. This vulnerability was fixed in Firefox 159, Firefox ESR 115.44, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6.
CVE-2026-113869 1 Mozilla 1 Thunderbird 2026-10-27 5.4 Medium
When Thunderbird asked for a security device password (for example a smartcard PIN or the Primary Password) while decrypting an S/MIME message, the message load could finish or be cancelled while the prompt was open. This freed the message decoder while it was still in use, causing a use-after-free and a potentially exploitable crash. This vulnerability was fixed in Thunderbird 158.0.1 and Thunderbird 153.6.
CVE-2026-110247 1 Mozilla 1 Thunderbird 2026-10-27 8.4 High
Several buffer-growth sites in libmime performed size arithmetic in 32-bit types without overflow checks. On a sufficiently large message the growth guard could fail open, or the buffer could be reallocated smaller than required, and a subsequent memcpy would then write attacker-controlled data across adjacent heap allocations. This vulnerability was fixed in Thunderbird 158 and Thunderbird 153.6.
CVE-2026-100801 1 Mozilla 2 Firefox, Thunderbird 2026-10-27 8.8 High

CVE-2026-8973 1 Mozilla 2 Firefox, Thunderbird 2026-10-21 8.8 High
