CVE-2025-61955

Local privilege escalation across security boundary

Published Oct 15, 2025 · Updated Oct 15, 2025

Privilege escalation in F5 F5OS-A and F5OS-C allows local authenticated users to cross a platform security boundary. F5 maps the flaw to improper neutralization of directives in dynamically evaluated code but has not disclosed the affected component or unsafe operation. Low-privileged local access is required, and exploitation crosses an appliance or chassis platform boundary; downstream tenant impact is not reported.
