Name of the Vulnerable Software and Affected Versions:
Media Manager for UserPro plugin for WordPress versions up to, and including, 3.11.0
Description:
The issue concerns unauthorized modification of data that can lead to privilege escalation due to a missing capability check on the `add capto img()` function. This allows unauthenticated attackers to update arbitrary options on the WordPress site, potentially enabling them to update the default role for registration to administrator and gain administrative user access to a vulnerable site.
Recommendations:
For versions up to, and including, 3.11.0, update to a version higher than 3.11.0 to resolve the issue.
As a temporary workaround, consider disabling the `add capto img()` function until a patch is available.
Restrict access to the WordPress site to minimize the risk of exploitation.
