CVE-2025-69119 Overview
CVE-2025-69119 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Corbesier WordPress theme in versions up to and including 1.15.0. The flaw is classified under CWE-98, which covers improper control of filename for include or require statements in PHP programs. Remote attackers can exploit the issue without authentication to include arbitrary local files through the vulnerable theme. Successful exploitation can lead to source code disclosure, sensitive configuration exposure, and potential remote code execution depending on server configuration. The vulnerability was published to the National Vulnerability Database (NVD) on 2026-06-17.
Critical Impact
Unauthenticated attackers can include arbitrary local files on WordPress sites running vulnerable Corbesier theme versions, exposing sensitive data including wp-config.php credentials.
Affected Products
- Corbesier WordPress theme versions <= 1.15.0
- WordPress installations using the Corbesier theme
- Any hosting environment running the vulnerable theme version

Technical Details for CVE-2025-69119
Vulnerability Analysis
The Corbesier theme contains an unauthenticated Local File Inclusion (LFI) flaw mapped to [CWE-98] (Improper Control of Filename for Include/Require Statement in PHP Program). The theme accepts user-supplied input and passes it to a PHP include or require statement without sufficient validation. Attackers can supply crafted path values to load arbitrary files from the underlying server filesystem. The issue requires no authentication, making any unauthenticated visitor a potential attacker. The EPSS data places the vulnerability at the 34.64 percentile for exploitation likelihood, with no public exploit currently confirmed.
Root Cause
The root cause is improper sanitization of file path parameters before they reach a PHP file inclusion function. The theme accepts attacker-controlled values and uses them directly in include, include_once, require, or require_once calls. Missing allow-list validation and missing path normalization permit directory traversal sequences and absolute paths to bypass any intended restrictions.
Attack Vector
The attack vector is network-based and requires no privileges or user interaction. An attacker sends a crafted HTTP request to a public endpoint exposed by the Corbesier theme. The malicious parameter contains a relative or absolute path pointing to sensitive files such as wp-config.php, /etc/passwd, or PHP session files. If the target server permits log poisoning, session injection, or upload of attacker-controlled content, the LFI can be escalated to remote code execution. Refer to the PatchStack Corbesier Theme Vulnerability advisory for additional technical context.
Detection Methods for CVE-2025-69119
Indicators of Compromise
- HTTP requests to Corbesier theme endpoints containing directory traversal sequences such as ../, ..%2f, or encoded null bytes.
- Requests with parameter values referencing sensitive system files like wp-config.php, /etc/passwd, or /proc/self/environ.
- Unexpected PHP errors in web server logs referencing file inclusion failures from theme files under /wp-content/themes/corbesier/.
- Outbound or filesystem access from the web server process to paths outside the WordPress document root.
Detection Strategies
- Inspect web server access logs for requests targeting /wp-content/themes/corbesier/ with suspicious path-style parameters.
- Deploy Web Application Firewall (WAF) rules that flag directory traversal patterns and absolute path references in query strings.
- Monitor PHP error logs for failed to open stream or No such file or directory messages tied to theme components.
- Correlate anomalous file read activity on WordPress hosts with inbound HTTP requests to the theme.
Monitoring Recommendations
- Enable verbose access logging on WordPress front-end servers and forward logs to a centralized analytics platform.
- Alert on access attempts to sensitive files including wp-config.php, .htaccess, and /etc/passwd originating from web processes.
- Track first-seen URL parameters to the Corbesier theme to surface previously unseen exploit attempts.
- Review file integrity monitoring output for unexpected modifications inside the theme directory.
How to Mitigate CVE-2025-69119
Immediate Actions Required
- Identify all WordPress instances running the Corbesier theme and confirm the installed version.
- Disable or remove the Corbesier theme on any site running version 1.15.0 or earlier until a patched release is available.
- Restrict public access to vulnerable sites through WAF rules blocking directory traversal patterns.
- Rotate WordPress secrets and database credentials if exploitation evidence is found in access logs.
Patch Information
At the time of NVD publication, no fixed version is referenced in the available CVE record. Administrators should monitor the PatchStack Corbesier Theme Vulnerability advisory and the theme vendor's release channel for an updated version above 1.15.0 that addresses the LFI flaw.
Workarounds
- Switch to a maintained WordPress theme until a patched Corbesier release is published.
- Apply WAF or reverse proxy rules that block requests containing ../, encoded traversal sequences, or absolute filesystem paths in parameters.
- Configure PHP open_basedir to confine file inclusion to the WordPress installation directory.
- Disable allow_url_include and verify allow_url_fopen is set to Off to limit inclusion abuse.
