SCA: security update for github.com/axllent/mailpit (GHSA-524m-q5m7-79mm)

medium Tenable Cloud Security Plugin ID 436717

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2026-22689)
