CVE-2026-2269 Overview
The Uncanny Automator – Easy Automation, Integration, Webhooks & Workflow Builder Plugin for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in all versions up to, and including, 7.0.0.3 via the download_url() function. This vulnerability allows authenticated attackers with Administrator-level access to make arbitrary web requests originating from the web application, enabling them to query and modify information from internal services. Additionally, the plugin stores remote file contents on the server, which can be leveraged to upload arbitrary files on the affected site's server, potentially enabling remote code execution.
Critical Impact
Authenticated attackers with Administrator privileges can exploit this SSRF vulnerability to access internal services, exfiltrate sensitive data, and potentially achieve remote code execution through arbitrary file uploads.
Affected Products
- Uncanny Automator Plugin for WordPress versions up to and including 7.0.0.3
- WordPress sites using vulnerable versions of the Uncanny Automator plugin
- Internal services accessible from the affected WordPress server

Technical Details for CVE-2026-2269
Vulnerability Analysis
This vulnerability exists in the Uncanny Automator plugin's implementation of the download_url() function. The function fails to properly validate and sanitize user-supplied URLs before making server-side requests. When an authenticated administrator makes a request through this functionality, the server processes the URL without adequate restrictions, allowing requests to be directed to arbitrary locations including internal network resources.
The vulnerability is classified under CWE-434 (Unrestricted Upload of Dangerous File Type), as the plugin stores downloaded content on the server without proper validation. This creates a dual-threat scenario: the SSRF component enables reconnaissance and potential data exfiltration from internal services, while the file storage behavior can be chained to achieve arbitrary file upload capabilities.
The attack requires network access and authenticated administrator-level privileges, limiting the attack surface but still presenting significant risk in shared hosting environments or where multiple administrators exist.
Root Cause
The root cause stems from insufficient input validation and URL scheme restrictions in the download_url() function. The plugin fails to implement proper safeguards including:
- Allowlist-based URL validation to restrict requests to approved external domains
- Blocking of internal IP ranges (127.0.0.0/8, 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16)
- Restriction of URL schemes (blocking file://, gopher://, and other dangerous protocols)
- Proper validation of downloaded file types before storage
Attack Vector
The attack is executed over the network and requires an authenticated session with Administrator-level privileges. An attacker can craft malicious requests through the vulnerable download_url() function to:
- Probe internal network services by requesting internal IP addresses or hostnames
- Access cloud metadata endpoints (e.g., AWS EC2 metadata at 169.254.169.254)
- Interact with internal APIs and databases that trust requests from localhost
- Upload malicious files by pointing the function to attacker-controlled servers hosting PHP webshells or other malicious content
The vulnerability mechanism exploits the trust relationship between the WordPress server and internal network services. When the server makes requests on behalf of the attacker, these requests appear to originate from a trusted internal source, bypassing firewall rules and access controls designed to block external access.
Detection Methods for CVE-2026-2269
Indicators of Compromise
- Unusual outbound HTTP/HTTPS requests from the WordPress server to internal IP ranges (10.x.x.x, 172.16.x.x-172.31.x.x, 192.168.x.x)
- Requests to cloud metadata endpoints such as 169.254.169.254
- Unexpected file uploads in WordPress upload directories with suspicious extensions or content
- Access logs showing administrator-initiated requests to the Uncanny Automator plugin endpoints with unusual URL parameters
Detection Strategies
- Monitor web server access logs for requests containing internal IP addresses or localhost references in URL parameters
- Implement egress filtering rules and alert on attempts to access internal network ranges from the WordPress application
- Deploy file integrity monitoring on WordPress upload directories to detect unauthorized file additions
- Review WordPress activity logs for administrator actions involving the Uncanny Automator plugin's URL download functionality
Monitoring Recommendations
- Configure web application firewalls (WAF) to inspect and block SSRF patterns in request parameters
- Enable DNS query logging to detect resolution requests for internal hostnames from the web server
- Implement alerting for any new PHP files created in writable WordPress directories
- Monitor for unusual network connections originating from the web server process to internal services
How to Mitigate CVE-2026-2269
Immediate Actions Required
- Update the Uncanny Automator plugin to a patched version (above 7.0.0.3)
- Audit administrator accounts and remove unnecessary elevated privileges
- Review recent file uploads and administrator activity for signs of compromise
- Implement network segmentation to limit the web server's access to internal services
Patch Information
The vulnerability has been addressed in the plugin codebase. Security patches are available through the official WordPress plugin repository. For detailed information about the specific changes implemented, refer to the WordPress Plugin Changeset and the Wordfence Vulnerability Report.
Workarounds
- Restrict administrator access to only trusted users and implement strong authentication mechanisms including multi-factor authentication
- Deploy a web application firewall (WAF) configured to block SSRF attack patterns and requests to internal IP ranges
- Implement network-level egress filtering to prevent the WordPress server from making requests to internal network segments
- If the plugin functionality is not critical, consider temporarily disabling the Uncanny Automator plugin until patching is complete
# Configuration example - WordPress .htaccess rules to restrict plugin access
# Add to WordPress root .htaccess file
<IfModule mod_rewrite.c>
RewriteEngine On
# Block direct access to Uncanny Automator sensitive endpoints
RewriteCond %{REQUEST_URI} ^/wp-content/plugins/uncanny-automator/.*$ [NC]
RewriteCond %{QUERY_STRING} (url|download|fetch)= [NC]
RewriteRule .* - [F,L]
</IfModule>
