CVE-2025-49279: Blogvy Path Traversal Vulnerability

CVE-2025-49279 Overview

CVE-2025-49279 is a PHP Local File Inclusion (LFI) vulnerability in the unfoldwp Blogvy WordPress theme. The flaw stems from improper control of the filename used in PHP include or require statements [CWE-98]. Attackers can manipulate file path parameters to load arbitrary local PHP files within the web server's accessible scope. The issue affects all Blogvy theme versions up to and including 1.0.7. Successful exploitation enables disclosure of sensitive files, configuration data, and in some configurations, execution of attacker-controlled PHP code. The vulnerability is network-exploitable without authentication or user interaction, though attack complexity is rated high.

Critical Impact
Unauthenticated attackers can include arbitrary local PHP files, leading to information disclosure and potential remote code execution on affected WordPress sites.

Affected Products

unfoldwp Blogvy WordPress theme versions up to and including 1.0.7
WordPress installations using the vulnerable Blogvy theme
Any web server hosting the affected theme code

Technical Details for CVE-2025-49279

Vulnerability Analysis

The Blogvy theme passes user-controllable input into a PHP file inclusion construct without adequate validation or path sanitization. PHP File Inclusion vulnerabilities [CWE-98] occur when the filename argument to include, require, include_once, or require_once derives from request data. An attacker submits a crafted parameter referencing a local file path, and the PHP interpreter loads and executes that file in the application's context.

The vulnerability allows access to PHP source files, WordPress configuration data such as wp-config.php, and other readable files on the host. If an attacker can place controlled content on disk through upload features, log poisoning, or session files, the LFI primitive can escalate to remote code execution. The Patchstack advisory confirms the local inclusion behavior across all Blogvy releases through 1.0.7.

Root Cause

The root cause is missing or insufficient validation of a filename parameter consumed by a PHP file inclusion function. The theme accepts an externally supplied value and concatenates it into an include path without restricting traversal sequences or enforcing an allowlist of permitted templates.

Attack Vector

The attack vector is network-based. An attacker sends an HTTP request to a vulnerable Blogvy endpoint with a manipulated parameter pointing to a target file. No authentication or user interaction is required. The high attack complexity reflects environmental conditions such as PHP configuration, path resolution behavior, or required race conditions for full exploitation. Verified exploit code is not publicly listed in the references for this CVE. See the Patchstack WordPress Vulnerability Report for technical details.

Detection Methods for CVE-2025-49279

Indicators of Compromise

HTTP requests containing directory traversal sequences such as ../ targeting Blogvy theme files under /wp-content/themes/blogvy/
Requests referencing sensitive files including wp-config.php, /etc/passwd, or PHP session files in query parameters
Unexpected PHP file reads recorded in web server access logs originating from theme endpoints
New or modified PHP files in upload directories created shortly before suspicious inclusion requests

Detection Strategies

Inspect web server logs for query strings passing file paths or path traversal patterns to Blogvy theme scripts
Deploy web application firewall (WAF) rules that flag LFI payloads targeting WordPress theme parameters
Monitor PHP error logs for include() or require() failures referencing unexpected paths
Enumerate installed WordPress themes and flag any Blogvy installation at version 1.0.7 or earlier

Monitoring Recommendations

Forward WordPress and web server logs to a centralized logging platform for query parameter analysis
Alert on access to wp-config.php content patterns appearing in HTTP responses
Track file integrity on the wp-content/themes/blogvy/ directory and PHP upload paths
Correlate inbound HTTP traffic with file system reads of sensitive configuration files

How to Mitigate CVE-2025-49279

Immediate Actions Required

Identify all WordPress installations using the Blogvy theme at version 1.0.7 or earlier
Deactivate the Blogvy theme until a vendor-supplied patched version is available
Apply WAF rules blocking path traversal and LFI payloads against theme endpoints
Rotate WordPress secrets, database credentials, and API keys if exploitation is suspected

Patch Information

At the time of publication, the NVD entry and the Patchstack WordPress Vulnerability Report list affected versions through 1.0.7. Administrators should monitor the vendor channel for an updated Blogvy release and apply it immediately upon availability.

Workarounds

Switch the active theme to a maintained alternative until a patched Blogvy version ships
Restrict PHP open_basedir to the WordPress directory to limit file inclusion scope
Set allow_url_include to Off in php.ini to prevent escalation to remote file inclusion
Enforce least-privilege file permissions on wp-config.php and other sensitive files

bash

# Configuration example
# php.ini hardening to limit file inclusion impact
allow_url_include = Off
allow_url_fopen = Off
open_basedir = "/var/www/html:/tmp"

# Example WAF rule pattern (ModSecurity) blocking traversal in theme requests
SecRule REQUEST_URI "@contains /wp-content/themes/blogvy/" \
  "chain,deny,status:403,id:1004927901,msg:'Blogvy LFI attempt'"
  SecRule ARGS "@rx (\.\./|wp-config\.php|/etc/passwd)" "t:none,t:urlDecode"
