CVE-2022-2839: Zephyr-one zephyr project manager cross-site scripting vulnerability

Zephyr One · Zephyr Project Manager

The Zephyr Project Manager WordPress plugin before 3.2.55 does not have any authorisation as well as CSRF in all its AJAX actions, allowing unauthenticated users to call them either directly or via CSRF attacks. Furthermore, due to the lack of sanitisation and escaping, it could also allow them to perform Stored Cross-Site Scripting attacks against logged in admins.
