Attack-Flow Graph

Executive Summary

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]

Impact Analysis

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]

Detection Guidance

There are no specific detection commands or network/system detection methods provided for this vulnerability. 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]

Mitigation Strategies

Since there is no official fix or patched version available as of the publication date, immediate mitigation steps include using Patchstack's offered mitigation services to protect affected sites and restricting user privileges to prevent unprivileged users from performing higher-privilege actions within the Crumber plugin.
