CVE-2026-62096: Biolife Path Traversal Vulnerability

CVE-2026-62096 Overview

CVE-2026-62096 is an unauthenticated Local File Inclusion (LFI) vulnerability affecting the Biolife WordPress theme in versions up to and including 3.2.3. The flaw is categorized under CWE-98 (Improper Control of Filename for Include/Require Statement in PHP Program). Remote attackers can abuse the vulnerability without authentication to include arbitrary files on the server. Successful exploitation can lead to disclosure of sensitive files and, under certain conditions, execution of attacker-controlled PHP code within the WordPress runtime.

Critical Impact
Unauthenticated remote attackers can include arbitrary local files on sites running Biolife theme versions <= 3.2.3, enabling source and configuration disclosure and potential code execution.

Affected Products

Biolife WordPress theme versions <= 3.2.3
WordPress sites with the Biolife theme installed and activated
Any multisite or hosting environment serving the vulnerable theme

Technical Details for CVE-2026-62096

Vulnerability Analysis

The vulnerability resides in a theme component that passes attacker-controlled input into a PHP include or require statement without proper validation. Because the include path is derived from untrusted request data, attackers can traverse the filesystem and load files outside the intended theme directory. The flaw requires no authentication and no user interaction, which makes it exposed to opportunistic scanning across the public internet. The attack complexity is elevated because successful exploitation depends on specific request parameters, path construction, and the server's PHP configuration.

Root Cause

The root cause is improper control of a filename used in a PHP include directive, consistent with CWE-98. The theme accepts a request parameter and uses it to build a path passed into include/require without allowlisting valid templates or canonicalizing the resulting path. This design allows directory traversal sequences and absolute paths to reach the include statement.

Attack Vector

Exploitation occurs over the network against the HTTP interface of the WordPress site. An attacker crafts a request to a vulnerable theme endpoint and supplies a path parameter pointing to a target file on disk. The included file is executed in the WordPress PHP context, exposing contents such as wp-config.php secrets, session data, or log files. If an attacker can plant PHP into a readable location (for example, uploads, logs, or session files), the LFI can be chained into remote code execution. See the Patchstack Biolife Theme Vulnerability advisory for additional technical details.

Detection Methods for CVE-2026-62096

Indicators of Compromise

HTTP requests to Biolife theme paths containing traversal sequences such as ../, %2e%2e%2f, or URL-encoded null bytes.
Access log entries referencing sensitive files like wp-config.php, /etc/passwd, or /proc/self/environ in query parameters.
Unexpected PHP errors or warnings in web server logs referencing include() or require() with unusual path arguments.
New or modified PHP files under wp-content/uploads/ following suspicious LFI request patterns.

Detection Strategies

Review web server access logs for requests to Biolife theme endpoints with path-like query parameters.
Deploy Web Application Firewall (WAF) rules that identify directory traversal patterns in HTTP parameters.
Hunt for PHP processes spawning shells (sh, bash) or network utilities from the web server user context.
Correlate 200-response LFI probes with subsequent anomalous outbound connections from the host.

Monitoring Recommendations

Enable WordPress file integrity monitoring across wp-content/themes/biolife/ and the broader document root.
Alert on reads of wp-config.php outside of expected PHP-FPM worker activity.
Monitor for new administrator account creation or unexpected changes to WordPress option tables.

How to Mitigate CVE-2026-62096

Immediate Actions Required

Identify all WordPress installations running the Biolife theme and confirm the installed version.
Upgrade Biolife to a release later than 3.2.3 once the vendor publishes a fixed version.
If no patched version is available, deactivate and remove the Biolife theme from affected sites.
Rotate secrets referenced in wp-config.php, including database credentials and authentication salts, if LFI exploitation is suspected.

Patch Information

At the time of publication, refer to the Patchstack Biolife Theme Vulnerability advisory for the latest fixed version and vendor guidance. Apply the vendor-supplied update to all affected sites and verify the theme version after upgrading.

Workarounds

Place a WAF rule in front of the site that blocks requests containing directory traversal sequences in query parameters.
Restrict PHP open_basedir to the WordPress document root to limit the scope of includable files.
Set allow_url_include = Off and allow_url_fopen = Off in php.ini to prevent remote file inclusion chains.
Apply least-privilege filesystem permissions so the PHP worker cannot read sensitive system files.

bash

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