AnalysisAIv1 – Sep 15, 2026

Privilege escalation in Mozilla Firefox for Android allows an attacker who can get a user to open a crafted web page to gain privileges beyond those normally granted to web content, with high impact to confidentiality, integrity, and availability. Mozilla fixed the flaw in Firefox 156; no public exploit code and no active exploitation have been identified, and CISA's SSVC assessment rates exploitation as 'none' with automatable 'no'. The 8.8 CVSS score is driven entirely by a network attack vector plus required user interaction (UI:R), so real-world risk depends on convincing a target to browse attacker-controlled content rather than on mass scanning.
