The code accepts serialized data that could, in theory, be derived from attacker\u2011influenced application state. This creates a latent PHP object injection vulnerability: if an attacker supplies crafted serialized data, malicious PHP objects could be instantiated, potentially leading to remote code execution. No public endpoint currently injects objects into this data path, so the flaw is not immediately exploitable.", "risk_and_exploitability": "The CVSS score of 7.5 reflects a high severity, but the EPSS score of less than 1% indicates a low likelihood of exploitation at present. The vulnerability is not listed in the CISA KEV catalog.

The inferred attack vector is the deserialization of attacker\u2011controlled input into the changelog handling routine."}}}}, "created": "2026-02-23T14:35:11.534250+00:00", "updated": "2026-04-17T17:15:23.724001+00:00", "vendors": ["openitcockpit", "openitcockpit$PRODUCT$openitcockpit"]}
