CVE-2026-25307Network attack vector

Contributor-level script execution via unsanitized page content

Published Feb 19, 2026 · Updated Feb 19, 2026

Cross-site scripting in 8theme XStore Core before 5.7 allows remote authenticated users to inject scripts into pages. Insufficient sanitization and output escaping preserve contributor-controlled page content for execution when a visitor loads the page; published sources identify no specific input or DOM sink. Contributor-level access and a later page view are required, exposing the visitor's browser session to injected script actions.
