ContentStudio <= 1.2.5 - Missing Authorization

Missing Authorization
CVE CVE-2023-0556
CVSS Critical (9.8)
Publicly Published January 6, 2023
Last Updated January 22, 2024
Researcher Marco Wotschka
Description

The ContentStudio plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on several functions in versions up to, and including, 1.2.5. This makes it possible for unauthenticated attackers to obtain the blog metadata (via the function cstu_get_metadata) that includes the plugin's contentstudio_token. Knowing this token allows for other interactions with the plugin such as creating posts in versions prior to 1.2.5, which added other requirements to posting and updating.
