CVE-2025-69110: AirSupply Path Traversal Vulnerability

CVE-2025-69110 Overview

CVE-2025-69110 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the AirSupply WordPress theme in versions 2.0.0 and earlier. The flaw is classified under CWE-98, Improper Control of Filename for Include/Require Statement in PHP Program. Remote attackers can include arbitrary local files in PHP execution flow without authentication. Successful exploitation can lead to disclosure of sensitive files, configuration data, and potential code execution if attacker-controlled content reaches the included path.

Critical Impact
Unauthenticated attackers can read or execute arbitrary local files through the AirSupply theme, impacting confidentiality, integrity, and availability of the WordPress site.

Affected Products

AirSupply WordPress theme versions <= 2.0.0
WordPress installations using the vulnerable theme
Hosting environments running affected sites

Technical Details for CVE-2025-69110

Vulnerability Analysis

The AirSupply theme fails to validate user-supplied input passed to a PHP include or require statement. An attacker can craft an HTTP request that controls a file path parameter resolved by the theme's PHP code. Because the endpoint requires no authentication, exploitation is possible directly over the network.

The Exploit Prediction Scoring System (EPSS) currently estimates exploitation probability at 0.435%, placing the issue in the 34.65 percentile. While no public exploit is listed in CISA's Known Exploited Vulnerabilities catalog, WordPress theme LFI flaws frequently see opportunistic scanning shortly after disclosure.

Root Cause

The root cause is improper control of a filename passed to a PHP file inclusion function, as described by CWE-98. The theme accepts a request parameter and concatenates it into an inclusion path without sanitization, allow-list validation, or restriction to a fixed directory.

Attack Vector

The attack vector is network-based and requires no privileges or user interaction. An attacker sends an HTTP request to the vulnerable endpoint with a manipulated parameter referencing a local file path. The included file is then parsed by PHP, exposing source code, credentials in wp-config.php, or executing PHP within attacker-controlled content such as uploaded media. See the Patchstack WordPress Vulnerability Analysis for technical details.

Detection Methods for CVE-2025-69110

Indicators of Compromise

HTTP requests to AirSupply theme PHP files containing path traversal sequences such as ../ or encoded variants like %2e%2e%2f.
Access log entries referencing sensitive local paths including wp-config.php, /etc/passwd, or /proc/self/environ.
Unexpected PHP execution originating from the theme directory /wp-content/themes/air-supply/.

Detection Strategies

Inspect web server logs for query parameters carrying file paths or null-byte injection patterns targeting the theme.
Deploy a web application firewall rule that blocks directory traversal payloads to AirSupply theme endpoints.
Monitor PHP include/require activity through file integrity and runtime monitoring tools where available.

Monitoring Recommendations

Alert on HTTP 200 responses to anomalous theme requests carrying file-path parameters.
Watch for outbound connections initiated by php-fpm or the web server immediately after suspicious theme requests.
Track new or modified PHP files in wp-content/uploads/ that could be leveraged for inclusion-to-execution chains.

How to Mitigate CVE-2025-69110

Immediate Actions Required

Deactivate the AirSupply theme until a patched release is confirmed available.
Apply a temporary WAF rule to block path traversal patterns and absolute file paths in query strings targeting the theme.
Rotate any credentials exposed in wp-config.php if the site has been internet-facing while running the vulnerable version.

Patch Information

No vendor patch URL is referenced in the published advisory at this time. Consult the Patchstack advisory for updates, and upgrade to a version newer than 2.0.0 once released.

Workarounds

Restrict access to the affected theme directory via web server rules until a fix is deployed.
Set the PHP open_basedir directive to confine file inclusion to required directories only.
Disable allow_url_include and ensure allow_url_fopen is off in php.ini to limit inclusion-based escalation.

bash

# Configuration example - PHP hardening in php.ini
allow_url_include = Off
allow_url_fopen = Off
open_basedir = "/var/www/html:/tmp"

# Apache rule to block traversal patterns to the AirSupply theme
<Location "/wp-content/themes/air-supply/">
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (\.\./|%2e%2e%2f|/etc/passwd|wp-config) [NC]
    RewriteRule .* - [F,L]
