Because no verification is performed, a malicious payload supplied on the update path can be executed during installation, giving the attacker arbitrary code execution privileges in the context of the updater or the end user. This behaviour is consistent with CWE\u2011494, which relates to the exploitation of insecure data.", "risk_and_exploitability": "The CVSS score of 7.8 places the vulnerability in the high\u2011severity range. The description states that the attacker only needs to influence the update delivery path; the CVE does not specify the precise method, but control of that path would enable a malicious update to be downloaded and executed. No user interaction is required beyond this influence. While an EPSS score is unavailable and the vulnerability is not catalogued in CISA\u2019s KEV, the vendor has released fixes that address the underlying issue."}}}}, "created": "2026-03-30T20:55:16.791494+00:00", "updated": "2026-03-30T20:55:16.791528+00:00", "vendors": []}
