Security readout for executives and security teams
Plain-English summary
A low-privileged WordPress user could use Quick Restaurant Menu administrative AJAX functions on affected sites. The impact is content integrity and availability: menu items, and potentially other posts, could be changed or deleted without administrator approval.
Executive priority
Treat as high priority for restaurant or content-managed WordPress sites using this plugin. The risk is not server takeover from the provided evidence, but unauthorized content changes or deletion can directly disrupt operations and customer-facing information.
Technical view
Quick Restaurant Menu through version 2.0.2 lacks capability checks on administrator-oriented AJAX actions. Because one action does not verify that a supplied post ID belongs to a menu item, an authenticated subscriber-level user can trigger menu management functions and may alter or delete arbitrary posts.
Likely exposure
Exposure is limited to WordPress sites running Quick Restaurant Menu versions up to and including 2.0.2 with authenticated user access, including subscriber-level accounts. Public anonymous exploitation is not supported by the provided sources.
Exploitation context
The CVE is not listed as CISA KEV in the bundle, and no cited source here confirms active exploitation. The attack requires a valid low-privilege WordPress account and no user interaction.
Researcher notes
The core weakness is CWE-862 missing authorization on AJAX handlers in includes/admin/ajax-functions.php. The important validation point is authorization enforcement and object ownership checking for post IDs used by menu actions. Avoid assuming exploit-in-the-wild without additional evidence.
Mitigation direction
- Inventory WordPress sites for Quick Restaurant Menu installations.
- Move off versions up to and including 2.0.2 using vendor or WordPress repository guidance.
- Disable or remove the plugin where it is not business-critical.
- Limit untrusted subscriber-level accounts until remediation is complete.
- Review recent content changes and deletions on affected sites.
Validation and detection
- Confirm installed Quick Restaurant Menu version on each WordPress site.
- Check whether low-privilege accounts exist on affected sites.
- Review logs for unexpected AJAX menu-management activity by non-admin users.
- Verify important posts and menu items have not been altered or deleted.
- Confirm backups can restore impacted WordPress content if needed.
