SCA: security update for github.com/axllent/mailpit (GHSA-mpf7-p9x7-96r3)

high Tenable Self-Hosted Container Security Plugin ID 438115

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 1.29.2, the Link Check API
(/api/v1/message/{ID}/link-check) is vulnerable to Server-Side Request Forgery (SSRF). The server performs
HTTP HEAD requests to every URL found in an email without validating target hosts or filtering
private/internal IP addresses. The response returns status codes and status text per link, making this a
non-blind SSRF. In the default configuration (no authentication on SMTP or API), this is fully exploitable
remotely with zero user interaction. This is the same class of vulnerability that was fixed in the HTML
Check API (CVE-2026-23845 / GHSA-6jxm-fv7w-rw5j) and the screenshot proxy (CVE-2026-21859 /
GHSA-8v65-47jx-7mfr), but the Link Check code path was not included in either fix. Version 1.29.2 fixes
this vulnerability. (CVE-2026-27808)
