In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts.

CVE-2022-3155: Attachment files saved to disk on macOS could be executed without warning (low)
When saving or opening an email attachment on macOS, Thunderbird did not set attribute com.apple.quarantine on the received file. If the received file was an application and the user attempted to open it, then the application was started immediately without asking the user to confirm.
CVE-2022-3266: Out of bounds read when decoding H264 (high)
An out-of-bounds read can occur when decoding H264 video. This results in a potentially exploitable crash.
CVE-2022-40956: Content-Security-Policy base-uri bypass (low)
When injecting an HTML base element, some requests would ignore the CSP's base-uri settings and accept the injected element's base instead.
CVE-2022-40957: Incoherent instruction cache when building WASM on ARM64 (low)
Inconsistent data in instruction and data cache when creating wasm code could lead to a potentially exploitable crash.
This bug only affects Thunderbird on ARM64 platforms.
CVE-2022-40958: Bypassing Secure Context restriction for cookies with __Host and __Secure prefix (moderate)
By injecting a cookie with certain special characters, an attacker on a shared subdomain which is not a secure context could set and thus overwrite cookies from a secure context, leading to session fixation and other attacks.
CVE-2022-40959: Bypassing FeaturePolicy restrictions on transient pages (high)
During iframe navigation, certain pages did not have their FeaturePolicy fully initialized leading to a bypass that leaked device permissions into untrusted subdocuments.
CVE-2022-40960: Data-race when parsing non-UTF-8 URLs in threads (high)
Concurrent use of the URL parser with non-UTF-8 data was not thread-safe. This could lead to a use-after-free causing a potentially exploitable crash.
CVE-2022-40962: Memory safety bugs fixed in Thunderbird 102.3 (high)
Mozilla developers Nika Layzell, Timothy Nikkel, Sebastian Hengst, Andreas Pehrson, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.2. 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.
