SCA: security update for alextselegidis/easyappointments (GHSA-pm5p-7w5h-jm5q)

low Tenable Cloud Security Plugin ID 446690

Description

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

 - Easy!Appointments is a self hosted appointment scheduler. In versions prior to 1.6.0,
 `Caldav::connect_to_server` at `application/controllers/Caldav.php:60` hands the request's `caldav_url` to
 a Guzzle `REPORT` call without scheme or host validation. A logged-in backend user (admin, provider, or
 secretary) reaches loopback, RFC1918, and link-local hosts on the deployment's network. The Guzzle
 exception path returns the upstream status code plus ~120 bytes of response body in the JSON `message`
 field (`Caldav.php:74-78`), so the SSRF is semi-blind. Version 1.6.0 contains a patch. (CVE-2026-52840)

There is no known solution at this time.
