Session hijacking via missing WebSocket origin validation
Published Sep 14, 2023 · Updated Sep 25, 2024
Cross-site WebSocket hijacking in Movim before 0.22 allows remote attackers to access a victim's XMPP session via a malicious site. Core.php accepted non-internal WebSocket connections without validating Sec-Fetch-Site or Origin against the configured base URI. A victim must be authenticated and visit attacker-controlled content; the resulting socket exposes XMPP data and actions in that session.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
