Authenticated script execution via undisclosed DOM operation
Published Dec 30, 2025 · Updated Dec 30, 2025
DOM-based XSS in 8theme XStore Core before 5.6 allows remote authenticated users to execute scripts after user interaction. The public CNA and Patchstack records do not identify the affected DOM source, sink, parameter, file, or function, so the wrong client-side operation remains undisclosed. Contributor-level access and a separate user's action are required; successful exploitation executes attacker-controlled script in that user's browser context.

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.
