CVE-2025-32259: WP ULike Authorization Bypass Vulnerability

CVE-2025-32259 Overview

CVE-2025-32259 is a missing authorization vulnerability affecting the WP ULike WordPress plugin developed by Alimir. The flaw impacts all versions from n/a through <= 4.7.9.1 and enables unauthenticated attackers to perform actions that should require permission checks. According to the Patchstack Vulnerability Report, the issue is classified as a content spoofing vulnerability resulting from broken access control [CWE-862]. The vulnerability is exploitable over the network without authentication or user interaction and impacts integrity.

Critical Impact
Unauthenticated attackers can invoke protected plugin functionality and manipulate content served by WP ULike, undermining data integrity on affected WordPress sites.

Affected Products

Technical Details for CVE-2025-32259

Vulnerability Analysis

The vulnerability stems from a missing authorization check within the WP ULike plugin. The plugin exposes functionality without validating whether the requesting user has the required capability or role to perform the action. This weakness maps to [CWE-862] Missing Authorization.

Because the flaw affects integrity but not confidentiality or availability, attackers cannot directly read sensitive data or crash the site. Instead, they can modify or spoof content managed by the plugin. The Patchstack advisory categorizes the issue as content spoofing, indicating that attackers can inject or manipulate content displayed to legitimate site visitors.

Root Cause

The root cause is the absence of capability or nonce verification on one or more plugin endpoints. WordPress plugins are expected to call functions such as current_user_can() and check_ajax_referer() before executing state-changing actions. WP ULike versions through 4.7.9.1 fail to enforce these controls consistently.

Attack Vector

An attacker sends crafted HTTP requests to a vulnerable WordPress site running WP ULike. No authentication or user interaction is required. The attacker abuses the exposed endpoint to trigger plugin actions that should be restricted to privileged users, producing spoofed content that appears legitimate to visitors.

No verified proof-of-concept code has been published. See the Patchstack Vulnerability Report for additional technical details.

Detection Methods for CVE-2025-32259

Indicators of Compromise

Unexpected modifications to content, likes, ratings, or user-facing counters managed by the WP ULike plugin.
Anonymous HTTP POST requests targeting WP ULike AJAX or REST endpoints from a single or rotating source address.
Access log entries showing repeated calls to admin-ajax.php with action parameters referencing ulike from unauthenticated sessions.

Detection Strategies

Inventory WordPress installations and identify sites running WP ULike at version 4.7.9.1 or earlier.
Correlate web server access logs with WordPress audit logs to spot unauthenticated calls to plugin endpoints.
Enable a WordPress activity plugin or web application firewall log source to record plugin-level events for later analysis.

Monitoring Recommendations

Alert on high-volume anonymous requests to wp-admin/admin-ajax.php where the action parameter references WP ULike handlers.
Baseline normal like or vote counts and alert when values change outside expected patterns.
Forward WordPress and web server logs to a centralized platform for retention and cross-site correlation.

How to Mitigate CVE-2025-32259

Immediate Actions Required

Update the WP ULike plugin to a version later than 4.7.9.1 as soon as the vendor releases a fixed release.
Audit WordPress sites for the presence of the WP ULike plugin and prioritize patching internet-facing installations.
Review recent content, ratings, and vote records for signs of spoofing or manipulation.

Patch Information

Refer to the Patchstack Vulnerability Report for the current patch status and vendor guidance. Apply the fixed plugin version through the WordPress admin dashboard or by replacing plugin files with the vendor-provided release.

Workarounds

Deactivate and remove the WP ULike plugin until a patched version is available if the functionality is not business critical.
Deploy web application firewall rules to block unauthenticated POST requests to WP ULike AJAX and REST endpoints.
Restrict access to wp-admin/admin-ajax.php and plugin REST routes by source IP where feasible.

bash

# Configuration example: block unauthenticated WP ULike AJAX actions at the web server
location = /wp-admin/admin-ajax.php {
    if ($arg_action ~* "^(wp_ulike|ulike)") {
        return 403;
    }
}
