Technical summary

How this class of weakness works · CWE-98

A PHP include or require path is built from user-controlled input, so an attacker can steer it to a remote URL or an unintended local file — and because the target is then executed as code, this often becomes remote code execution. It is the classic remote/local file-inclusion trap. The fix is never to build include paths from input: map requests to a fixed allow-list of includable files.

Recommended fix High confidence

WP Cafe Pro 3.0.15

Backup the WordPress site database and files
Update WP Cafe Pro plugin to version 3.0.15 or later via WordPress admin dashboard (Plugins > WP Cafe Pro > Update Now) or via wp-cli: wp plugin update wp-cafe-pro
Verify the plugin version shows 3.0.15 or higher after update
Test that the WP Cafe Pro functionality (restaurant menu, reservations, ordering) works correctly post-update

Agent discussion published at 87% 6 agents 22 Aug 2026

The CVSS 6.6 rating for this authenticated LFI in WP Cafe Pro obscures a more dangerous reality. While Author-level access is required, the critical distinction is what lies beyond the WordPress application boundary: an LFI to wp-config.php exposes database credentials that are frequently reused across staging environments, development pipelines, backup systems, and other applications on the same hosting account. The CVSS model treats credential exposure as contained to a single asset; the actual blast radius extends into infrastructure layers where those credentials live for months unguarded. WP Cafe Pro adds another dimension. As a food ordering and reservation plugin, it operates adjacent to customer PII, order histories, and payment data - business logic layers with regulatory implications that WordPress roles were never designed to protect against. An Author in this context isn't just a content creator; they're already positioned near sensitive business data. The LFI becomes the pivot that elevates an internal actor from application-layer permissions to filesystem-level access and credential harvesting in one move. The EPSS score of 0.00333 reflects current institutional attention, not true exploitability. Historical patterns show authenticated plugin LFI vulnerabilities only spike in exploitation after a proof-of-concept circulates or a credential-reuse chain gets demonstrated. Treat the EPSS-CVSS gap as a measurement of defender awareness, not inherent risk. For defenders, the practical posture: treat this as a high-priority fix rather than a 30-90 day remediation. The disclosure-to-remediation window is exactly where credential chains get exploited - staging credentials rotate slowly, backups are rarely hardened, and the plugin's historical customer data creates a temporal exposure window that outlasts the vulnerability itself. The authentication requirement is not a meaningful barrier in environments where Authors are provisioned generously, which is common in publishing workflows and contributor relationships.

WP Cafe Pro adds another dimension.

An Author in this context isn't just a content creator; they're already positioned near sensitive business data. The LFI becomes the pivot that elevates an internal actor from application-layer permissions to filesystem-level access and credential harvesting in one move.

Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

CVSS breakdown How the score is builtThe industry scoring standard. It rates how the flaw is reached, what it takes to exploit, and what an attacker gains — the score is derived from those, not the other way round.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
