CVE-2025-68507: Icegram Auth Bypass Vulnerability

CVE-2025-68507 Overview

CVE-2025-68507 is a Missing Authorization vulnerability (CWE-862) affecting the Icegram WordPress plugin. This Broken Access Control flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized actions within WordPress installations using the affected plugin.

The vulnerability stems from missing authorization checks within the Icegram plugin, which is commonly used for creating popups, welcome bars, and opt-in forms on WordPress websites. Attackers can leverage this misconfiguration to bypass intended access restrictions and perform operations that should require proper authentication or elevated privileges.

Critical Impact

Unauthorized users may be able to access restricted functionality or modify plugin settings without proper authorization, potentially compromising site security and user data.

Affected Products

• Icegram WordPress Plugin versions through 3.1.35
• WordPress installations using the vulnerable Icegram plugin

Technical Details for CVE-2025-68507

Vulnerability Analysis

This vulnerability is classified as Missing Authorization (CWE-862), a type of Broken Access Control flaw. The Icegram plugin fails to implement proper authorization checks for certain operations, allowing users to perform actions beyond their intended privilege level.

In WordPress plugin architecture, proper authorization typically involves verifying user capabilities using functions like current_user_can() before executing sensitive operations. When these checks are missing or improperly implemented, attackers can directly access functionality intended only for administrators or other privileged users.

The impact of this vulnerability depends on which specific functions lack authorization checks, but Missing Authorization flaws in WordPress plugins can potentially allow attackers to modify plugin settings, access sensitive data, or perform administrative actions without proper credentials.

Root Cause

The root cause is the absence of proper authorization verification in the Icegram plugin code. WordPress plugins should validate that the current user has appropriate capabilities before processing requests that modify data or access protected functionality. The vulnerable versions of Icegram (through 3.1.35) fail to implement these necessary authorization checks in one or more code paths.

Attack Vector

An attacker can exploit this vulnerability by sending crafted requests to the WordPress site running a vulnerable version of Icegram. Since no proper authorization is enforced, the attacker can bypass intended access controls by:

1. Identifying plugin endpoints or AJAX handlers that lack authorization checks
2. Crafting HTTP requests that directly invoke these unprotected functions
3. Executing operations that should require administrative or authenticated access

The attack can typically be performed remotely without authentication, making it particularly concerning for public-facing WordPress installations.

Detection Methods for CVE-2025-68507

Indicators of Compromise

• Unexpected modifications to Icegram plugin settings or configurations
• Unusual activity in WordPress admin logs related to the Icegram plugin
• Creation or modification of popups, welcome bars, or opt-in forms by unauthorized users
• Suspicious HTTP requests targeting Icegram plugin endpoints

Detection Strategies

• Review WordPress access logs for unusual requests to /wp-admin/admin-ajax.php with Icegram-related action parameters
• Monitor plugin configuration changes for unauthorized modifications
• Implement Web Application Firewall (WAF) rules to detect exploitation attempts targeting WordPress plugin vulnerabilities
• Conduct regular security audits of installed WordPress plugins

Monitoring Recommendations

• Enable comprehensive logging for WordPress admin activities and plugin operations
• Configure alerts for configuration changes to the Icegram plugin
• Monitor for unusual patterns of requests from unauthenticated users to plugin endpoints
• Implement file integrity monitoring for Icegram plugin files

How to Mitigate CVE-2025-68507

Immediate Actions Required

• Update the Icegram plugin to a patched version when available (versions after 3.1.35)
• If updates are not available, consider temporarily deactivating the Icegram plugin until a fix is released
• Implement additional access controls at the web server or WAF level
• Review and audit any changes made to Icegram configurations for potential unauthorized modifications

Patch Information

Organizations should monitor the Icegram plugin update channels and the Patchstack vulnerability database for information about patched versions. Update to a version newer than 3.1.35 when a security fix becomes available.

Workarounds

• Restrict access to WordPress admin AJAX endpoints using web server configurations
• Implement additional authentication layers for administrative functions
• Use security plugins that can enforce capability checks on plugin operations
• Consider using a Web Application Firewall with WordPress-specific rulesets to filter malicious requests
• Limit user registration and ensure proper role assignment on the WordPress site
