CVE-2025-58829: Ai Auto Tool Content Writing Assistant SSRF

CVE-2025-58829 Overview

CVE-2025-58829 is a Server-Side Request Forgery (SSRF) vulnerability in the AI Auto Tool Content Writing Assistant (Gemini Writer, ChatGPT) All in One WordPress plugin. The flaw affects all plugin versions up to and including 2.3.3. An authenticated attacker with low privileges can coerce the vulnerable WordPress site to issue arbitrary HTTP requests to internal or external resources. The weakness is tracked as CWE-918: Server-Side Request Forgery.

Critical Impact
Attackers can abuse the plugin to probe internal network services, reach cloud metadata endpoints, and pivot through the WordPress host to otherwise unreachable systems.

Affected Products

WordPress plugin: Ai Auto Tool Content Writing Assistant (Gemini Writer, ChatGPT) All in One (ai-auto-tool)
All versions from n/a through <= 2.3.3
WordPress sites with the plugin installed and activated

Technical Details for CVE-2025-58829

Vulnerability Analysis

The plugin exposes functionality that fetches remote URLs on behalf of authenticated users. The implementation does not adequately validate or restrict the destination of those requests. An attacker with at least low-privilege authenticated access can supply a crafted URL that the server dereferences. The server then issues an HTTP request from its own network position, bypassing perimeter firewalls and reaching internal-only services.

Because the CVSS vector marks the scope as changed, successful exploitation affects resources beyond the vulnerable plugin itself. Potential targets include internal admin panels, databases, Redis or Memcached instances, and cloud instance metadata services such as the AWS Instance Metadata Service (IMDS). The vulnerability requires high attack complexity, meaning exploitation depends on conditions outside the attacker's direct control.

Root Cause

The root cause is missing allowlist-based URL validation in the plugin's HTTP fetching routines. User-controllable input flows into a server-side HTTP client without filtering destination hostnames, IP ranges (including RFC1918, loopback, and link-local addresses), or supported URL schemes. This matches the pattern described in CWE-918.

Attack Vector

Exploitation requires network access to the WordPress site and valid low-privilege credentials. The attacker submits a URL parameter targeting an internal resource, for example http://127.0.0.1:6379/ or http://169.254.169.254/latest/meta-data/. The plugin fetches the resource server-side and may return response content, status codes, or timing data that discloses internal service state. See the Patchstack SSRF Vulnerability Advisory for additional technical details.

Detection Methods for CVE-2025-58829

Indicators of Compromise

Outbound HTTP requests from the WordPress host to internal IP ranges such as 127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16
Requests originating from the WordPress PHP worker process targeting 169.254.169.254 or other cloud metadata endpoints
Unexpected wp-admin/admin-ajax.php or REST API calls to plugin endpoints with URL parameters pointing to internal hosts
Web server access logs showing authenticated users triggering plugin fetch actions with non-standard URL schemes (file://, gopher://, dict://)

Detection Strategies

Monitor outbound connections from the web server process for traffic to private address space and metadata endpoints
Deploy web application firewall rules that inspect plugin request parameters for internal IPs and localhost references
Enable WordPress audit logging to correlate authenticated user actions with outbound requests
Review plugin version inventories across managed WordPress fleets to identify installations at or below version 2.3.3

Monitoring Recommendations

Alert on connections from PHP-FPM or Apache worker processes to IMDS endpoints and internal management ports
Baseline normal outbound destinations for the WordPress host and flag deviations
Capture full HTTP request and response metadata for plugin endpoints to support incident reconstruction

How to Mitigate CVE-2025-58829

Immediate Actions Required

Identify all WordPress instances running the AI Auto Tool Content Writing Assistant plugin at version 2.3.3 or earlier
Deactivate and remove the plugin if a patched version is not yet available for your environment
Restrict authenticated access to trusted users only and audit existing low-privilege accounts
Enforce IMDSv2 on AWS workloads to require session tokens for metadata access

Patch Information

No fixed version is listed in the referenced advisory at the time of publication. Monitor the Patchstack advisory and the plugin's WordPress.org page for an updated release addressing CVE-2025-58829.

Workarounds

Place the WordPress host behind an egress proxy that denies requests to RFC1918, loopback, and link-local address ranges
Block the WordPress host from reaching cloud metadata endpoints at the network layer
Apply a virtual patch via web application firewall rules that reject plugin requests containing internal host references or non-HTTP schemes
Remove the plugin until the vendor publishes a fix if business operations allow
