CVE-2024-0750
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 · uneditedA bug in popup notifications delay calculation could have made it possible for an attacker to trick a user into granting permissions. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.
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 · moderate confidenceA logic bug in the popup notification delay calculation mechanism allows attackers to manipulate permission prompt timing, potentially tricking users into granting unintended permissions through social engineering of the delay window.

-
Identify installed Firefox versionNavigate to Firefox menu > Help > About Firefox, or enter 'about:support' in the address bar to view the version numberAffected if The displayed version is below 122.0 (for regular Firefox)
-
Identify installed Firefox ESR versionNavigate to Firefox menu > Help > About Firefox, or enter 'about:support' in the address bar to view the version numberAffected if The displayed version is below 115.7 (for Firefox ESR)
-
Identify installed Thunderbird versionNavigate to Thunderbird menu > Help > About Thunderbird to view the version numberAffected if The displayed version is 115.7 or below
-
Verify browser platform and update channelCheck 'about:support' page to confirm if running standard release, ESR, or Thunderbird, and note the exact version stringAffected if Running any Firefox or Thunderbird version below the fixed releases (122.0, 115.7)
A user is affected if they are running Mozilla Firefox below 122.0, Firefox ESR below 115.7, or Thunderbird at or below 115.7, as the permission prompt delay calculation can be manipulated.
