CVE-2025-48356Network attack vector

Stored script execution via undisclosed input handling

Published Aug 28, 2025 · Updated Apr 28, 2026

Stored XSS in Isra Kanpress 1.1 and earlier allows remote authenticated users to execute scripts in another user's browser. Patchstack and the public source record do not identify the affected field, request parameter, rendering function, or missing sanitization operation. Contributor-level access can store the payload, but execution requires a privileged user to open the affected content, exposing that user's browser session to script-driven actions.
