Name of the Vulnerable Software and Affected Versions Kyverno versions prior to 1.16.4

Description In apiCall service mode, the admission controller automatically attaches its ServiceAccount token to outbound HTTP requests when explicit authorization headers are absent. This allows an attacker to exfiltrate the token by directing apiCall requests to external or attacker-controlled endpoints, potentially granting full control over cluster resources and Kyverno policies.

Recommendations Update to version 1.16.4 or later.
