CVE-2025-69147: Putter Path Traversal Vulnerability

CVE-2025-69147 Overview

CVE-2025-69147 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Putter WordPress theme in versions up to and including 1.17. The flaw is classified under [CWE-98] (Improper Control of Filename for Include/Require Statement in PHP Program). An unauthenticated remote attacker can supply attacker-controlled input that influences a PHP include or require statement, causing the application to load arbitrary local files. Successful exploitation can lead to disclosure of sensitive configuration data, execution of attacker-staged PHP content, and full compromise of the hosting WordPress site.

Critical Impact
Unauthenticated attackers can include arbitrary local files through the Putter theme, leading to source code disclosure and potential remote code execution on affected WordPress installations.

Affected Products

Putter WordPress theme versions <= 1.17
WordPress installations bundling the vulnerable Putter theme
Any hosting environment serving content through the affected theme files

Technical Details for CVE-2025-69147

Vulnerability Analysis

The Putter theme contains a PHP file inclusion routine that fails to validate or sanitize user-supplied input before passing it to a dynamic include/require call. Because the affected endpoint is reachable without authentication, any unauthenticated visitor can manipulate the request to control which file path PHP loads at runtime. The issue is tracked under [CWE-98], the canonical weakness class for PHP Remote/Local File Inclusion bugs.

The attack requires no privileges and no user interaction, but the attack complexity is rated high, indicating that reliable exploitation may depend on specific server configuration, path layout, or readable file targets. When exploited successfully, the attacker can read arbitrary files accessible to the web server user, including wp-config.php, which contains database credentials and authentication secrets.

Root Cause

The root cause is improper control of a filename parameter used inside a PHP include statement. The theme accepts a request parameter and concatenates it into a path that is then executed by include, require, include_once, or require_once. Without an allowlist, normalization, or extension enforcement, traversal sequences such as ../ and absolute paths reach the include call directly.

Attack Vector

The vulnerability is exploited over the network by sending a crafted HTTP request to a vulnerable theme endpoint. The attacker supplies a path traversal payload or an absolute path in the vulnerable parameter. PHP then resolves and executes the referenced file. If the attacker can stage PHP content in a writable location reachable by the server (for example, uploaded media, log files, or session files), LFI can be escalated to remote code execution.

No verified public proof-of-concept code is referenced in the advisory. See the Patchstack Vulnerability Report for technical details.

Detection Methods for CVE-2025-69147

Indicators of Compromise

HTTP requests to Putter theme PHP files containing path traversal sequences such as ../, ..%2f, or URL-encoded null bytes in query parameters
Web server access logs showing references to sensitive files like wp-config.php, /etc/passwd, or PHP session paths through theme endpoints
Unexpected outbound network connections or new PHP files appearing in wp-content/uploads/ shortly after suspicious theme requests
PHP error log entries referencing include() or require() failures with attacker-controlled paths

Detection Strategies

Inspect WordPress access logs for GET or POST parameters targeting files inside the Putter theme directory with traversal patterns
Deploy web application firewall rules that block requests containing directory traversal sequences against theme PHP endpoints
Correlate file integrity monitoring events on wp-content/themes/putter/ and the WordPress root with inbound HTTP request telemetry

Monitoring Recommendations

Continuously monitor WordPress installations for the presence and version of the Putter theme, flagging any deployment of versions <= 1.17
Forward web server, PHP-FPM, and WordPress audit logs to a centralized analytics platform for retroactive hunting on LFI patterns
Alert on read access to wp-config.php or other secrets from web-facing PHP processes outside of normal application startup

How to Mitigate CVE-2025-69147

Immediate Actions Required

Identify all WordPress sites running the Putter theme at version 1.17 or earlier and prioritize them for remediation
Deactivate and remove the Putter theme until a patched release is confirmed available from the theme vendor
Rotate any secrets stored in wp-config.php, including database credentials and authentication keys, on sites that were exposed
Review web server and PHP logs for prior exploitation attempts and investigate any matching activity

Patch Information

No fixed version is listed in the published advisory at the time of CVE assignment. Refer to the Patchstack Vulnerability Report for the latest vendor status. Until a fixed release is published, removing the theme is the recommended path.

Workarounds

Block access to vulnerable theme PHP endpoints at the web server or WAF layer using request path and parameter filtering
Enforce open_basedir restrictions in PHP to limit which files the web server process can read or include
Disable PHP execution in user-writable directories such as wp-content/uploads/ to reduce LFI-to-RCE escalation paths
Apply least-privilege file system permissions so that the web server user cannot read sensitive configuration outside the WordPress document root

bash

# Example WAF / Nginx rule to block traversal against the Putter theme directory
location ~* /wp-content/themes/putter/.*\.php$ {
    if ($args ~* "(\.\./|\.\.%2f|%00)") {
        return 403;
    }
}

# Example php.ini hardening
# open_basedir = /var/www/html:/tmp
# allow_url_include = Off
# allow_url_fopen = Off
