The injection capability enables the attacker to retrieve sensitive information across the network, effectively bypassing authorization controls. The weakness corresponds to CWE-77, a classic command injection flaw that can expose data the user is not permitted to see.", "risk_and_exploitability": "The CVSS base score of 6.5 indicates a medium severity. No EPSS score is available, and the vulnerability is not listed in CISA\u2019s KEV catalog. Exact exploitation details are not provided in the source, but the described command injection suggests that an attacker needs network visibility and the ability to send crafted requests to the Copilot service. Given the lack of an EPSS ranking and the moderate CVSS score, the potential for exploitation remains realistic, warranting prompt remediation."}}}}, "created": "2026-03-20T08:55:55.805708+00:00", "updated": "2026-03-20T11:06:05.792674+00:00", "vendors": ["microsoft", "microsoft$PRODUCT$copilot"]}
