CVE-2024-7529
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe date picker could partially obscure security prompts. This could be used by a malicious site to trick a user into granting permissions. This vulnerability affects Firefox < 129, Firefox ESR < 115.14, Firefox ESR < 128.1, Thunderbird < 128.1, and Thunderbird < 115.14.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Firefox/Thunderbird date picker UI component can be positioned to partially obscure security permission prompts, allowing malicious websites to visually trick users into granting sensitive permissions (camera, microphone, location, etc.) without proper awareness.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Firefox versionOpen Firefox, click the menu button (three horizontal lines), select Help, then select About Firefox. The version number is displayed on the page that opens.Affected if Version is less than 129.0 (e.g., 128.x, 127.x, etc.)
-
Check installed Firefox ESR versionOpen Firefox ESR, click the menu button, select Help, then select About Firefox. The version number is displayed on the page that opens.Affected if Version is less than 115.14.0 OR version equals 128.0 exactly
-
Check installed Thunderbird versionOpen Thunderbird, click the menu button (three horizontal lines or Application Menu in newer versions), select Help, then select About Thunderbird. The version number is displayed.Affected if Version is less than 115.14.0 OR version equals 128.0.1 exactly
If any of the installed applications (Firefox, Firefox ESR, or Thunderbird) match their respective vulnerable version ranges, the date picker UI can be manipulated to obscure security permission prompts.
