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 · unedited
A select option could partially obscure security prompts. This could be used by a malicious site to trick a user into granting permissions. *This issue only affects Android versions of Firefox.* This vulnerability affects Firefox < 129.

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 confidence

On Android Firefox versions prior to 129, a malicious webpage can use a strategically positioned select dropdown element to partially obscure security permission prompts (e.g., geolocation, camera, microphone). This UI obfuscation enables social engineering attacks where users unknowingly grant dangerous permissions to attacker-controlled sites.

MitigationUpgrade Firefox for Android to version 129 or later. Organizations should push browser updates to managed devices and notify end users to update their browsers.
