CVE-2026-2554 — WCFM – Frontend Manager for WooCommerce along with Bookings Subscription Listings Compatible <= 6.7.25 - Authenticated (Vendor+) Insecure Direct Object Reference to Arbitrary User Deletion
The WCFM – Frontend Manager for WooCommerce along with Bookings Subscription Listings Compatible plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.7.25 via the 'wcfm_delete_wcfm_customer' due to missing validation on the 'customerid' user controlled key. This makes it possible for authenticated attackers, with Vendor-level access and above, to delete arbitrary users, including Administrators.
Who exploits it and how urgent it is
A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.
How the score was calculated
- EPSS 0.5% (30-day exploitation probability)+6
- Technical severity (high)+6
The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).
Triage
Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
Remediation
Fixes and mitigations documented by the sources — linked to the original advisory.
No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.
