CVE-2026-22326: Reprizo Path Traversal Vulnerability

CVE-2026-22326 Overview

CVE-2026-22326 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Reprizo WordPress theme in versions up to and including 1.0.8. The flaw is categorized under [CWE-98] (Improper Control of Filename for Include/Require Statement in PHP Program). Remote attackers can exploit the issue over the network without authentication or user interaction. Successful exploitation can disclose sensitive server-side files and, depending on the server configuration, lead to code execution.

Critical Impact
An unauthenticated remote attacker can include arbitrary local files through the Reprizo theme, exposing credentials, configuration data, and potentially enabling remote code execution on the underlying WordPress host.

Affected Products

WordPress theme: Reprizo
Versions: <= 1.0.8
Deployment: WordPress sites running the vulnerable theme

Technical Details for CVE-2026-22326

Vulnerability Analysis

The Reprizo theme contains an Improper Control of Filename for Include/Require Statement weakness [CWE-98]. PHP include, require, include_once, or require_once statements consume attacker-influenced input without enforcing a strict allow-list. As a result, the theme loads arbitrary files from the local filesystem at runtime.

LFI flaws in WordPress themes typically expose sensitive artifacts such as wp-config.php, which stores database credentials and secret keys. Attackers can also read /etc/passwd, web server logs, and session files. When log poisoning or PHP wrapper abuse is possible, LFI can escalate to remote code execution.

The attack requires no authentication and no user interaction, but the CVSS vector indicates higher attack complexity. This typically reflects environmental conditions such as specific request parameters, server configuration, or filter bypass requirements needed for reliable exploitation.

Root Cause

The root cause is unsanitized user input flowing into a PHP file inclusion sink within the theme. The theme accepts a filename or path value from a request parameter and passes it directly to an inclusion function without canonicalization, path normalization, or restriction to an approved directory.

Attack Vector

The attack vector is network-based. An attacker sends a crafted HTTP request to a Reprizo-enabled endpoint, supplying a traversal sequence or absolute path. The PHP interpreter then includes the target file in the response context. Refer to the Patchstack Vulnerability Report for technical specifics.

Detection Methods for CVE-2026-22326

Indicators of Compromise

Web server access logs showing path traversal sequences such as ../, ..%2f, or encoded variants targeting Reprizo theme endpoints
Requests containing references to sensitive files such as wp-config.php, /etc/passwd, or php://filter
Anomalous outbound responses from theme handlers containing file contents instead of rendered HTML

Detection Strategies

Inspect HTTP request parameters reaching /wp-content/themes/reprizo/ for filesystem path patterns and PHP stream wrappers
Correlate WordPress access logs with PHP error logs for failed to open stream or include() warnings tied to theme files
Apply web application firewall signatures for generic LFI payloads against WordPress theme directories

Monitoring Recommendations

Enable verbose logging on the WordPress host and forward access and PHP logs to a centralized log platform
Alert on repeated 200-status responses to theme requests containing traversal tokens
Monitor file read operations on wp-config.php by the PHP-FPM or web server process outside normal application flow

How to Mitigate CVE-2026-22326

Immediate Actions Required

Identify all WordPress instances using the Reprizo theme at version 1.0.8 or earlier
Deactivate the Reprizo theme on affected sites until a patched release is confirmed and applied
Rotate WordPress database credentials, salts, and API keys stored in wp-config.php if exposure is suspected
Review web logs for prior exploitation attempts dating back to theme installation

Patch Information

No fixed version has been published in the NVD record at the time of disclosure. Consult the Patchstack Vulnerability Report for vendor remediation status and upgrade guidance.

Workarounds

Block requests to Reprizo theme endpoints containing ../, php://, or absolute paths at the WAF or reverse proxy layer
Apply virtual patching via Patchstack or an equivalent WordPress security platform
Restrict PHP open_basedir to the WordPress document root to limit the filesystem scope reachable through inclusion
Disable allow_url_include and confirm allow_url_fopen is not required by the application

bash

# Example php.ini hardening to constrain inclusion scope
open_basedir = "/var/www/html:/tmp"
allow_url_include = Off
allow_url_fopen = Off
