Stored script execution via unsanitized post titles
Published Jan 11, 2024 · Updated Jun 17, 2025
Stored cross-site scripting in qkmc-rk RedBBS 1.0 allows remote authenticated users to execute script through a crafted post title. The post handler stores the title value without neutralizing executable markup and later returns it in a page viewed by another user. An attacker must register and submit a post, and exploitation occurs when a user browses the affected post, enabling script execution in that user’s browser.
