CVE-2026-41953 Details
Description
A vulnerability exists in BIG-IP systems where a highly privileged, authenticated attacker with at least the Resource Administrator role can modify configuration objects resulting in privilege escalation. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
A vulnerability in F5 BIG-IP systems allows a highly privileged, authenticated attacker with the Resource Administrator role to modify configuration objects, leading to privilege escalation. This issue affects several versions across the 16.x, 17.x, and 21.x branches. In Appliance mode deployments, the vulnerability can enable an attacker to cross a security boundary.
Users can upgrade to BIG-IP versions 17.5.1.6, 17.1.3.2, or 21.0.0.2. For more information about managing BIG-IP product hotfixes, refer to the F5 article K13123.
