CVE-2021-41731Public exploitNetwork attack vector

Stored script execution via unsanitized category names

Published Sep 16, 2022 · Updated Aug 4, 2024

Stored XSS in Sourcecodester News247 News Magazine 1.0 allows remote authenticated users to execute scripts through blog category names. The category-creation path stores an administrator-supplied name without neutralizing HTML, and category rendering inserts it into pages viewed by other users. Administrative access is required to plant the payload, and execution requires another user to visit a page that renders the malicious category.
