CVE-2026-63020
Low
Description
A vulnerability exists in an undisclosed BIG-IP Configuration utility page that may allow an attacker to spoof error messages Impact: An attacker may trick authenticated BIG-IP users into accessing malicious links and reflect a spoofed error message in the victim's BIG-IP Configuration utility web browser session. This is a control plane issue; there is no data plane exposure. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
