Vulnerability AssessmentAI

Exploitation Exploitation requires the victim to be running Firefox for Android on a version prior to 154 and to visit a malicious or attacker-controlled web page that triggers a download interaction. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 base score of 5.4 (Medium) reflects a moderate, realistic risk posture. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker hosts a malicious web page that initiates a download and crafts the response or associated UI elements to misrepresent the file's name, type, or origin within the Firefox for Android Downloads panel. A user who taps the download notification or opens the Downloads view sees a spoofed representation - for example, a malicious APK presented as a PDF - and may take action based on that false context. …
Remediation Upgrade Firefox for Android to version 154 or later, which contains the vendor-confirmed fix per Mozilla advisory MFSA2026-74 (https://www.mozilla.org/security/advisories/mfsa2026-74/). … Detailed patch versions, workarounds, and compensating controls in full report.
