CVE-2025-62154: 
WordPress vulnerability analysis and mitigation

CVE-2025-62154 is a Missing Authorization vulnerability in the AI Content Writing Assistant (Content Writer, ChatGPT, Image Generator) All in One WordPress plugin developed by Recorp. The flaw allows authenticated, low-privileged attackers to exploit incorrectly configured access control security levels to modify data. All plugin versions up to and including 1.1.7 are affected; version 1.1.8 and later contain the fix. The vulnerability was published on December 31, 2025, and carries a CVSS v3.1 base score of 4.3 (Medium), assigned by Patchstack (Patchstack, Red Hat CVE).

The root cause is classified as CWE-862 (Missing Authorization) — the plugin fails to properly verify whether an authenticated user has the appropriate permissions before allowing access to certain functionality. This misconfigured access control allows a network-accessible, low-privileged authenticated user (e.g., a subscriber-level WordPress account) to invoke restricted plugin actions without proper capability checks. No user interaction is required, and attack complexity is low, making the flaw straightforward to exploit once an attacker has any valid WordPress account on the target site (Patchstack, Red Hat CVE).

Successful exploitation results in a limited integrity impact — authenticated low-privileged users can modify data or trigger plugin functionality that should be restricted to higher-privileged roles (e.g., administrators or editors). There is no direct confidentiality or availability impact based on the CVSS assessment. The scope is limited to the affected WordPress installation, but unauthorized data modification could affect AI-generated content, plugin settings, or related site content managed by the plugin (Patchstack).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported for CVE-2025-62154. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. The EPSS score is approximately 0.026%, indicating a very low probability of exploitation in the near term. Exploitation requires a valid (low-privileged) account on the target WordPress site, which limits opportunistic mass exploitation (Red Hat CVE).

1. Reconnaissance: Identify WordPress sites running the ai-content-writing-assistant plugin at version 1.1.7 or earlier using tools like WPScan or by inspecting plugin metadata in publicly accessible readme.txt files.
2. Obtain low-privileged access: Register or obtain credentials for a low-privileged WordPress account (e.g., subscriber role) on the target site.
3. Identify unprotected endpoints: Enumerate AJAX actions or REST API endpoints registered by the plugin that lack proper capability checks (e.g., via source code review of the plugin's PHP files).
4. Send unauthorized request: Craft and send an authenticated HTTP request (with a valid WordPress nonce or session cookie) to the vulnerable endpoint, invoking a restricted action such as modifying plugin settings or content.
5. Achieve unauthorized modification: The server processes the request without verifying the user's role, resulting in unauthorized data modification within the plugin's scope (Patchstack).

• Logs: WordPress access logs showing authenticated POST requests to wp-admin/admin-ajax.php or REST API endpoints associated with the ai-content-writing-assistant plugin from low-privileged user accounts at unusual times or frequencies.
• Application: Unexpected changes to plugin settings or AI-generated content configurations not initiated by an administrator.
• User Activity: Subscriber or contributor-level accounts performing actions typically restricted to editors or administrators within the plugin's functionality.

The vendor (Recorp) has released a patched version of the plugin. Update the AI Content Writing Assistant plugin to version 1.1.8 or later via the WordPress plugin dashboard or by downloading the updated package from the WordPress plugin repository. No configuration-based workaround is documented; upgrading is the recommended and only confirmed remediation. Site administrators should also audit low-privileged user accounts and review recent plugin activity logs for signs of unauthorized access (Patchstack, Red Hat CVE).

The vulnerability was discovered and reported by Patchstack, which assigned the CVE and published the advisory on December 31, 2025. No notable independent researcher commentary, media coverage, or significant community discussion has been identified beyond standard vulnerability database aggregation and automated social media CVE tracking accounts (Patchstack).
