What is CVE-2026-27742?

Bludit version 3.16.2 is susceptible to a stored cross-site scripting vulnerability due to inadequate server-side sanitation of post content. This flaw allows authenticated users to inject arbitrary JavaScript into the content area of posts. When these posts are viewed by other users, the malicious script executes within their browser sessions, potentially leading to session hijacking, credential theft, and unauthorized content manipulation. Mitigating this vulnerability is critical to protecting user data and maintaining the integrity of the application.

Affected Version(s)
