CSRF in Patreon WordPress
CVE-2021-24230
The Jetpack Scan team identified a Cross-Site Request Forgery vulnerability in the Patreon WordPress plugin before 1.7.0, allowing attackers to make a logged in user overwrite or create arbitrary user metadata on the victim’s account once visited. If exploited, this bug can be used to overwrite the “wp_capabilities” meta, which contains the affected user account’s roles and privileges. Doing this would essentially lock them out of the site, blocking them from accessing paid content.
