Local File Inclusion in the Edge-Themes "Aalto" WordPress theme (all versions up to and including 1.8) lets an authenticated attacker control a filename passed to a PHP include/require statement, exposing local files and potentially executing PHP. The flaw was reported by Patchstack and carries CVSS 7.5; there is no public exploit identified at time of analysis and it is not listed in CISA KEV. Despite the CWE-98 "Remote File Inclusion" classification, the described impact is Local File Inclusion.

DescriptionCVE.org

Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Edge-Themes Aalto aalto allows PHP Local File Inclusion.This issue affects Aalto: from n/a through <= 1.8.

Executive ViewAI

Why It Matters

The Edge-Themes 'Aalto' WordPress theme (versions through 1.8) contains a local file inclusion vulnerability (CVE-2026-57788) with no public exploit identified at time of analysis. Authenticated users can read sensitive server files and potentially execute PHP code, exposing organizations to configuration file theft and unauthorized site access through any compromised or low-privilege user account.

Recommended Action

Within 24 hours: identify all WordPress installations using Edge-Themes 'Aalto' version 1.8 or earlier; disable the theme on all non-business-critical sites and restrict administrative access by IP whitelist. Within 7 days: deploy Web Application Firewall (WAF) rules to block directory traversal and PHP file inclusion patterns; enable enhanced logging on remaining affected installations. Within 30 days: continuously monitor vendor advisory for patch release; if no patch is released within 30 days, execute migration plan to replace the theme with a maintained alternative.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: (1) Restrict theme functionality via WAF rules blocking file inclusion payloads; (2) Enforce principle of least privilege by removing unnecessary user roles (Contributor, Author) that could be compromised; (3) Implement file integrity monitoring on critical files (wp-config.php, database configuration); (4) Disable the theme entirely on non-essential properties; (5) Review audit logs for suspicious file-access patterns.

Attack Technique

Local File Inclusion vulnerabilities occur when an application accepts user-controlled input to specify which file should be loaded or executed, typically through functions like PHP's `include()`, `require()`, or `fopen()`.

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
