CVE-2025-30576: Hacklog Remote Image Autosave CSRF Flaw

CVE-2025-30576 Overview

CVE-2025-30576 is a Cross-Site Request Forgery (CSRF) vulnerability affecting the Hacklog Remote Image Autosave WordPress plugin developed by HuangYe WuDeng. The flaw affects all plugin versions up to and including 2.1.0. An attacker can trick an authenticated WordPress user into submitting a forged request that performs unintended state-changing actions inside the plugin. The vulnerability maps to CWE-352: Cross-Site Request Forgery. Exploitation requires user interaction, such as clicking a crafted link or visiting an attacker-controlled page while authenticated to the target WordPress site.

Critical Impact
A successful CSRF attack allows a remote attacker to invoke plugin actions on behalf of an authenticated WordPress user, resulting in limited integrity impact on affected sites.

Affected Products

Hacklog Remote Image Autosave plugin versions up to and including 2.1.0
WordPress installations with the hacklog-remote-image-autosave plugin enabled
Vendor: HuangYe WuDeng

Technical Details for CVE-2025-30576

Vulnerability Analysis

The Hacklog Remote Image Autosave plugin exposes plugin actions that lack anti-CSRF protection. The plugin handlers do not validate a WordPress nonce (wp_nonce) or verify the request origin before executing sensitive operations. An attacker crafts an HTML page containing a form or image tag targeting the plugin's endpoint. When an authenticated administrator or privileged user visits the malicious page, the browser transmits the request with valid session cookies. The server processes the request as if the victim initiated it. The exploitation requires user interaction, and the attacker cannot read the response due to same-origin restrictions.

Root Cause

The root cause is missing CSRF token validation in the plugin's action handlers. WordPress provides wp_verify_nonce() and check_admin_referer() for this purpose, but the plugin does not invoke these checks before performing state-changing operations. Without a nonce, the server cannot distinguish between a legitimate request from the WordPress admin interface and a forged request originating from an attacker-controlled page.

Attack Vector

The attack vector is network-based and requires the victim to visit a malicious page while authenticated to the target WordPress site. The attacker hosts a page containing an auto-submitting HTML form or JavaScript that targets the plugin endpoint. Because the request travels with the victim's authentication cookies, the plugin executes the requested action. Refer to the Patchstack Vulnerability Report for further technical detail.

Detection Methods for CVE-2025-30576

Indicators of Compromise

Unexpected plugin actions or configuration changes originating from administrator sessions
HTTP POST or GET requests to hacklog-remote-image-autosave endpoints with Referer headers pointing to external domains
Unusual outbound requests initiated by the plugin to attacker-controlled image URLs

Detection Strategies

Inspect web server access logs for requests to plugin endpoints where the Referer header does not match the site's own domain
Correlate authenticated administrator sessions with off-hours or unusual browsing patterns preceding plugin activity
Monitor WordPress audit logs for plugin state changes that lack a corresponding admin UI interaction

Monitoring Recommendations

Enable a WordPress activity logging plugin to record all plugin configuration changes with source IP and referrer
Deploy a Web Application Firewall (WAF) with rules that flag missing or invalid wp_nonce parameters on plugin endpoints
Alert on HTTP requests to plugin admin endpoints originating from cross-origin referrers

How to Mitigate CVE-2025-30576

Immediate Actions Required

Deactivate the Hacklog Remote Image Autosave plugin until a patched version is confirmed available from the vendor
Restrict WordPress administrator access to trusted networks and enforce short session lifetimes
Require administrators to log out of WordPress before browsing untrusted sites

Patch Information

At the time of publication, no fixed version has been identified in the NVD advisory. The vulnerability affects all versions through 2.1.0. Review the Patchstack Vulnerability Report for updates on vendor remediation.

Workarounds

Uninstall the plugin if it is not essential to site operations
Deploy WAF rules that block requests to the plugin's endpoints when the Referer header does not match the site origin
Enforce SameSite=Strict or SameSite=Lax on WordPress authentication cookies to reduce cross-site request risk

bash

# Example WAF rule concept blocking cross-origin POST requests to the plugin
# Adapt for ModSecurity, Nginx, or your WAF of choice
