CVE-2026-22689 - Mailpit is vulnerable to Cross-Site WebSocket Hijacking (CSWSH) allowing unauthe

CVE ID : CVE-2026-22689 Published : Jan. 10, 2026, 6:15 a.m. | 1 hour, 19 minutes ago Description : Mailpit is an email testing tool and API for developers. Prior to version 1.28.2, the Mailpit WebSocket server is configured to accept connections from any origin. This lack of Origin header validation introduces a Cross-Site WebSocket Hijacking (CSWSH) vulnerability. An attacker can host a malicious website that, when visited by a developer running Mailpit locally, establishes a WebSocket connection to the victim's Mailpit instance (default ws://localhost:8025). This allows the attacker to intercept sensitive data such as email contents, headers, and server statistics in real-time. This issue has been patched in version 1.28.2.
