CVE-2025-58681: Easy Quotes Auth Bypass Vulnerability

CVE-2025-58681 Overview

CVE-2025-58681 is a missing authorization vulnerability in the Jürgen Müller Easy Quotes WordPress plugin (easy-quotes). The flaw affects all versions up to and including 1.2.4. The plugin fails to enforce proper access control checks, allowing unauthenticated attackers to reach functionality that should be restricted. The issue is categorized under CWE-862: Missing Authorization and stems from incorrectly configured access control security levels.

Critical Impact
Remote attackers can exploit the flaw over the network without authentication or user interaction, leading to limited disclosure of information handled by the plugin.

Affected Products

Technical Details for CVE-2025-58681

Vulnerability Analysis

The Easy Quotes plugin exposes functionality without validating whether the requesting user holds the required capabilities. Under WordPress plugin design guidance, sensitive actions should be gated by current_user_can() checks and nonce validation. The plugin omits or misconfigures these checks, resulting in broken access control [CWE-862].

The attack surface is reachable across the network with low attack complexity. No credentials or user interaction are required. Successful exploitation impacts confidentiality of data processed by the plugin, while integrity and availability remain unaffected.

Root Cause

The root cause is incorrectly configured access control security levels on plugin endpoints. Handlers registered through WordPress AJAX or admin action hooks execute without verifying user roles or capabilities. Attackers can invoke these handlers directly by issuing crafted HTTP requests to the target site.

Attack Vector

An unauthenticated remote attacker sends HTTP requests to WordPress endpoints registered by the Easy Quotes plugin. Because the plugin does not verify authorization, the endpoint returns data or performs actions intended for privileged users. Detailed technical information is available in the Patchstack Vulnerability Report.

No verified public proof-of-concept code is available at this time. The EPSS score is 0.263% with a percentile of 17.723, indicating a low predicted probability of exploitation activity in the near term.

Detection Methods for CVE-2025-58681

Indicators of Compromise

Unauthenticated HTTP requests to WordPress admin-ajax.php referencing Easy Quotes plugin actions.
Access log entries showing repeated calls to plugin-specific endpoints from a single external IP.
Unexpected disclosure of quote data or plugin-managed records in web server responses.

Detection Strategies

Monitor WordPress access logs for calls to easy-quotes handlers originating from unauthenticated sessions.
Alert on HTTP 200 responses to plugin endpoints where the request lacks a valid wp_nonce parameter.
Correlate anomalous traffic patterns targeting the plugin path with absence of an authenticated session cookie.

Monitoring Recommendations

Enable verbose logging on the WordPress site and forward logs to a centralized SIEM for continuous review.
Track the plugin version installed across managed WordPress sites and flag any host still running 1.2.4 or earlier.
Deploy a web application firewall rule set to alert on direct calls to plugin AJAX actions without valid authentication context.

How to Mitigate CVE-2025-58681

Immediate Actions Required

Inventory all WordPress instances and identify sites running the Easy Quotes plugin at version 1.2.4 or earlier.
Deactivate the Easy Quotes plugin on affected sites until a patched release is confirmed installed.
Restrict administrative and AJAX endpoints behind IP allowlists or authentication gateways where feasible.

Patch Information

At the time of NVD publication, no fixed version is listed in the advisory. Site administrators should consult the Patchstack Vulnerability Report for the latest remediation guidance and apply any plugin update released by the vendor beyond version 1.2.4.

Workarounds

Uninstall the Easy Quotes plugin if it is not business-critical.
Add web application firewall rules to block unauthenticated requests to plugin endpoints such as admin-ajax.php with Easy Quotes action parameters.
Enforce authentication on /wp-admin/ and AJAX handlers at the reverse proxy layer for defense in depth.

bash

# Example nginx rule to block unauthenticated calls to Easy Quotes AJAX actions
location = /wp-admin/admin-ajax.php {
    if ($arg_action ~* "^easy[_-]quotes") {
        set $block_flag 1;
    }
    if ($http_cookie !~* "wordpress_logged_in") {
        set $block_flag "${block_flag}A";
    }
    if ($block_flag = "1A") {
        return 403;
    }
}
