CVE-2025-4645

Code execution via insufficient ACAP validation

Published Nov 11, 2025 · Updated Nov 11, 2025

Improper input validation in AXIS OS 12.0.0 through 12.6.6 allows attackers to execute arbitrary code through a malicious ACAP application. An ACAP configuration file accepts insufficiently validated values, but Axis has not disclosed the specific field or unsafe operation that converts them into code execution. Exploitation requires unsigned ACAP installation to be enabled and a victim to install the malicious application, bounding exposure to devices with that setting enabled.
