Stored script execution via unsanitized comments
Published Feb 29, 2024 · Updated Aug 5, 2024
Stored cross-site scripting in Markerhub eblog 1.0 allows remote authenticated users to execute scripts through crafted post comments. The comment reply endpoint accepts script-bearing content and stores it without effective neutralization before rendering it in a post page. Execution occurs when another user opens the affected post, exposing that user's browser session to script-controlled reads and actions.
