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
When switching between Android apps using the card carousel Firefox shows a black screen as its card image when a password-related screen was the last one being used. Prior to Firefox 144 the password edit screen was visible. This vulnerability was fixed in Firefox 144.

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

Firefox Android exposed sensitive password entry screens in the Android app switcher card carousel, allowing potential shoulder-surfing disclosure of credentials. When users switched apps, the password edit screen was visible as a preview thumbnail instead of being obscured. This was fixed in Firefox 144 by displaying a black screen instead of the actual password screen content.

MitigationUpdate Firefox for Android to version 144 or later. Organizations should ensure fleet-wide updates through mobile device management or user communication.
