Attack Vectors

CVE-2026-27071 is a Medium-severity (CVSS 5.3) vulnerability affecting WPCafe – Restaurant Menu, Online Food Ordering and Reservation Booking Solution (WordPress plugin slug: wp-cafe) in versions up to and including 3.0.7.

The issue can be triggered remotely over the internet and does not require a user to be logged in. In practical terms, this means an attacker can target any website running an affected WPCafe version by sending crafted requests to the vulnerable functionality.

Because the CVSS vector indicates no privileges and no user interaction (AV:N/PR:N/UI:N), this type of exposure is often attractive for broad, automated scanning and opportunistic attacks—especially for restaurant and hospitality brands where online ordering and reservations are business-critical.

Security Weakness

WPCafe versions ≤ 3.0.7 are vulnerable due to a missing authorization (capability) check on a function. In WordPress terms, the plugin does not properly confirm that the requester is allowed to perform the related action before executing it.

Wordfence’s advisory indicates this missing check can enable unauthenticated attackers to perform an unauthorized action. The published CVSS impact profile (C:N/I:L/A:N) suggests the primary risk is limited integrity impact rather than data theft or full site outage, but the business consequences can still be meaningful depending on what the affected action controls in your environment.

Technical or Business Impacts

Even with a Medium severity rating, missing authorization issues can directly affect revenue operations when the vulnerable plugin supports customer-facing flows like menus, online ordering, and reservations. If an unauthorized action is performed, the result can include unexpected changes to site behavior or business workflows that depend on WPCafe.

Business impacts may include:

Operational disruption: inconsistent ordering or booking experiences, staff time spent validating orders/reservations, and increased customer support volume.
Brand and customer trust risk: customers encountering incorrect availability, confusing menu details, or inconsistent booking confirmations may attribute the failure to your brand rather than the plugin.
Compliance and audit concerns: for organizations with change-management expectations (franchise operations, regulated environments, or strict internal controls), unauthorized changes—however limited—can create audit findings and incident-response overhead.

Remediation status: there is no known patch available at this time. Based on your risk tolerance, the most conservative option may be to uninstall the affected WPCafe plugin and replace it with an alternative. If you cannot remove it immediately, consider short-term mitigations such as increased monitoring for unexpected changes, tightening access controls around WordPress administration, and deploying web application firewall protections to reduce exposure while you transition.

Similar Attacks

Missing authorization and unauthenticated plugin flaws have been repeatedly abused in the WordPress ecosystem because they can be targeted at scale:

CVE-2018-19207 (WP GDPR Compliance) – a widely discussed WordPress plugin issue that enabled unauthorized actions and was actively exploited in the wild.
CVE-2020-25213 (WP File Manager) – a high-profile WordPress plugin vulnerability that saw broad exploitation and demonstrated how quickly attackers operationalize plugin weaknesses at internet scale.
