Can you explain this vulnerability to me?
CVE-2025-66143 is a broken access control vulnerability in the WordPress Crumber plugin (versions up to 1.0.10). It occurs due to missing authorization, authentication, or nonce token checks in certain plugin functions, which allows unprivileged users (like subscribers) to perform actions that normally require higher privileges. [1]
How can this vulnerability impact me? :
This vulnerability could allow users with low privileges to perform unauthorized actions within the plugin, potentially leading to unintended changes or access. However, it is considered low severity with a CVSS score of 5.4 and is unlikely to be exploited due to its low impact. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?

Detection would likely involve reviewing plugin versions and checking for unauthorized access attempts or privilege escalations related to the Crumber plugin, but no explicit commands are given. [1]
What immediate steps should I take to mitigate this vulnerability?
