CVE-2025-69116: Iona Path Traversal Vulnerability

CVE-2025-69116 Overview

CVE-2025-69116 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Iona WordPress theme in versions up to and including 1.0.8. The flaw maps to [CWE-98]: Improper Control of Filename for Include/Require Statement in PHP Program. Remote attackers can supply attacker-controlled input to a file inclusion directive without authentication. Successful exploitation allows reading sensitive server-side files and, depending on server configuration, executing arbitrary PHP code through included files. The issue 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 the Iona theme, exposing configuration data and potentially leading to remote code execution.

Affected Products

Iona WordPress theme versions <= 1.0.8
WordPress installations using the vulnerable theme
Any hosting environment serving the affected theme files

Technical Details for CVE-2025-69116

Vulnerability Analysis

The Iona theme contains an unauthenticated Local File Inclusion vulnerability classified under [CWE-98]. The theme accepts user-controlled input and passes it to a PHP file inclusion function such as include, require, include_once, or require_once without sufficient validation. Attackers reach the vulnerable code path over the network without supplying credentials.

Local File Inclusion enables an attacker to instruct the application to load files from the local filesystem. When the included content is interpreted as PHP, the attack escalates from information disclosure to code execution. Sensitive targets on a typical WordPress host include wp-config.php, which holds database credentials and authentication keys.

The Patchstack advisory for the Iona theme documents the issue and tracks the vulnerable version range. See the Patchstack Iona Theme Vulnerability advisory for technical references.

Root Cause

The root cause is improper sanitization of a user-supplied parameter that is concatenated into a PHP file inclusion statement. The theme does not enforce an allowlist of permitted files or strip path traversal sequences such as ../. Any request reaching the vulnerable endpoint can redirect the include target to arbitrary filesystem paths.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker sends a crafted HTTP request to the vulnerable theme endpoint with a manipulated parameter referencing a local file path. The web server resolves and includes the target file, returning its contents or executing it as PHP. Attackers commonly chain LFI with log poisoning, session file injection, or PHP wrappers to achieve code execution.

No verified public exploit code is currently available. The vulnerability mechanism is described in prose only; refer to the vendor advisory for technical details.

Detection Methods for CVE-2025-69116

Indicators of Compromise

HTTP requests to Iona theme files containing path traversal sequences such as ../../, ..%2f, or URL-encoded variants
Requests referencing sensitive system paths including /etc/passwd, wp-config.php, or PHP log files
Use of PHP wrappers such as php://filter, php://input, or data:// in request parameters
Unexpected outbound activity from the web server process following suspicious requests

Detection Strategies

Inspect web server access logs for parameter values containing directory traversal patterns targeting theme paths
Deploy web application firewall (WAF) rules that block path traversal and PHP wrapper signatures in query strings and POST bodies
Alert on PHP processes reading files outside the WordPress document root or theme directory
Correlate file system reads of wp-config.php with originating HTTP requests to identify exploitation attempts

Monitoring Recommendations

Forward WordPress and web server logs to a centralized analytics platform for retention and querying
Monitor process creation events spawned from PHP-FPM or the web server user for anomalous shell or network activity
Track file integrity for theme files, wp-config.php, and core WordPress directories
Baseline normal parameter values for theme endpoints and alert on deviations

How to Mitigate CVE-2025-69116

Immediate Actions Required

Identify all WordPress installations running the Iona theme at version 1.0.8 or earlier
Disable or remove the Iona theme on affected sites until a patched version is confirmed installed
Restrict web server permissions so the PHP process cannot read sensitive files outside the web root
Review web server and application logs for prior exploitation attempts targeting theme endpoints

Patch Information

Consult the Patchstack Iona Theme Vulnerability advisory for the latest patch status and remediation guidance. Update the Iona theme to a version higher than 1.0.8 once the vendor publishes a fixed release. If no patch is yet available, switch to an alternative supported theme.

Workarounds

Deploy WAF rules to block requests containing path traversal sequences and PHP stream wrappers
Set the PHP directive open_basedir to restrict file access to the WordPress installation directory
Disable PHP wrappers by configuring allow_url_include = Off and reviewing allow_url_fopen settings
Rotate WordPress secrets and database credentials in wp-config.php if exploitation is suspected

bash

# Example php.ini hardening to limit LFI impact
allow_url_include = Off
allow_url_fopen = Off
open_basedir = "/var/www/html:/tmp"
disable_functions = "exec,passthru,shell_exec,system,proc_open,popen"
