CVE-2024-30450Network attack vector

Authenticated browser script execution via stored input

Published Mar 29, 2024 · Updated Apr 28, 2026

Stored cross-site scripting in the Step-Byte-Service OpenStreetMap plugin 1.1.1 and earlier allows remote authenticated users to execute browser scripts. The published advisory does not identify the affected parameter, rendering path, or missing sanitization or output-encoding operation. Exploitation requires low-privileged access and interaction by another user; script execution is confined to that user's browser context and can read or alter content available to that session.
