CVE Catalog

CVE-2026-88828

MediumCVSS 5.4
Published: Updated: Translated: NVD NIST

Summary

The Blacklist Manager for WooCommerce WordPress plugin from 1.3.0 to 2.3.1 does not enforce its user blocking on every authentication path. This allows the holder of an account the site owner has blocked to keep authenticating with that account's privileges, without the block being enforced or recorded.

Risk Assessment

Blocked users can still access their accounts, undermining security controls and potentially leading to unauthorized actions. The lack of block recording makes incident detection difficult.

Recommendation

Update the Blacklist Manager for WooCommerce plugin to a version newer than 2.3.1 if a vendor patch is available. Verify that blocks are effectively enforced on all authentication paths.
