A flaw was found in mbin. The Markdown rendering component fails to properly escape nested image alternative text and link URLs. An authenticated remote attacker can exploit this stored Cross-Site Scripting (XSS) vulnerability by embedding malicious HTML into content such as posts, comments, or profile bios. When a victim views the affected content, the injected script executes within their browser session, potentially enabling unauthorized actions or data disclosure.
