Information disclosure via server-side request forgery
Published Aug 11, 2026 · Updated Aug 25, 2026
Server-side request forgery in Microsoft PowerShell Core before 7.4.19, 7.5.10, and 7.6.5 allows remote attackers to read data over a network. Microsoft has not publicly identified the affected cmdlet, code path, or validation failure; the CNA, NVD, and vendor advisory disclose only an SSRF condition in PowerShell Core. Microsoft's CVSS assessment marks user interaction as required, so exploitation depends on a user running attacker-supplied PowerShell content and is bounded to confidentiality exposure from network-reachable resources.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
