Privilege escalation via undisclosed Enterprise Policies flaw
Published Sep 15, 2026 · Updated Sep 15, 2026
Privilege escalation in Mozilla Firefox before 156 and Firefox ESR before 153.3 allows attackers to gain elevated privileges. Mozilla has not published the vulnerable policy-handling locus or the incorrect operation performed on untrusted input. The required access and resulting privilege level remain undisclosed, so exposure cannot be bounded beyond affected managed-browser installations.
