An attacker could have injected CSS into stylesheets accessible via internal URIs, such as resource:, and in doing so bypass a page's Content Security Policy. This vulnerability affects Firefox ESR < 91.11, Thunderbird < 102, Thunderbird < 91.11, and Firefox < 101.
CVE-2022-31742 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
An attacker could have exploited a timing attack by sending a large number of allowCredential entries and detecting the difference between invalid key handles and cross-origin key handles. This could have led to cross-origin account linking in violation of WebAuthn goals. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-31741 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 8.8 HIGH
A crafted CMS message could have been processed incorrectly, leading to an invalid memory read, and potentially further memory corruption. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-31740 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 8.8 HIGH
On arm64, WASM code could have resulted in incorrect assembly generation leading to a register allocation problem, and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-31739 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2026-06-17 N/A 8.8 HIGH
When downloading files on Windows, the % character was not escaped, which could have lead to a download incorrectly being saved to attacker-influenced paths that used variables such as %HOMEPATH% or %APPDATA%.<br>*This bug only affects Firefox for Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-31738 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
When exiting fullscreen mode, an iframe could have confused the browser about the current state of fullscreen, resulting in potential user confusion or spoofing attacks. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-31737 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 9.8 CRITICAL
A malicious webpage could have caused an out-of-bounds write in WebGL, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-31736 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 9.8 CRITICAL
A malicious website could have learned the size of a cross-origin resource that supported Range requests. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
CVE-2022-2505 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 8.8 HIGH
Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 102. 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 ESR < 102.1, Firefox < 103, and Thunderbird < 102.1.
CVE-2022-2226 1 Mozilla 1 Thunderbird 2026-06-17 N/A 6.5 MEDIUM
An OpenPGP digital signature includes information about the date when the signature was created. When displaying an email that contains a digital signature, the email's date will be shown. If the dates were different, then Thunderbird didn't report the email as having an invalid signature. If an attacker performed a replay attack, in which an old email with old contents are resent at a later time, it could lead the victim to believe that the statements in the email are current. Fixed versions of Thunderbird will require that the signature's date roughly matches the displayed date of the email. This vulnerability affects Thunderbird < 102 and Thunderbird < 91.11.
CVE-2022-2200 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 8.8 HIGH
If an object prototype was corrupted by an attacker, they would have been able to set undesired attributes on a JavaScript object, leading to privileged code execution. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
CVE-2022-29917 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 9.8 CRITICAL
Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 99 and Firefox ESR 91.8. 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 Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100.
CVE-2022-29916 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
Firefox behaved slightly differently for already known resources when loading CSS resources involving CSS variables. This could have been used to probe the browser history. This vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100.
CVE-2022-29914 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 6.5 MEDIUM
When reusing existing popups Firefox would have allowed them to cover the fullscreen notification UI, which could have enabled browser spoofing attacks. This vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100.
CVE-2022-29913 1 Mozilla 1 Thunderbird 2026-06-17 N/A 6.5 MEDIUM

CVE-2022-29909 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 8.8 HIGH
Documents in deeply-nested cross-origin browsing contexts could have obtained permissions granted to the top-level origin, bypassing the existing prompt and wrongfully inheriting the top-level permissions. This vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100.
CVE-2022-28289 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2026-06-17 N/A 8.8 HIGH
Mozilla developers and community members Nika Layzell, Andrew McCreight, Gabriele Svelto, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 91.7.
