Subscriber privilege escalation via undisclosed flaw
Published Aug 18, 2026 · Updated Aug 18, 2026
Privilege escalation in Theme-One Inc. The Grid 2.7.9.1 and earlier allows remote authenticated users to gain higher privileges via unspecified vectors. Patchstack's advisory and the published CVE record do not disclose the vulnerable endpoint, parameter, or function, so the flawed operation on untrusted input is not public. Exploitation requires a subscriber account and no user interaction; public sources state only that higher privileges can be gained, and they do not identify the final role or whether every exploit path reaches full site control.

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.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
