GHSA-H8VW-7X98-J7C4

Vulnerability from github – Published: 2023-01-28 00:30 – Updated: 2023-02-06 15:30

Details

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.

Severity ?

6.5 (Medium)
