What is CVE-2026-88827?

The Disable Users plugin for WordPress, up to version 1.0.5, contains a critical flaw where its account-disabling functionality is not properly enforced across all authentication pathways. As a result, users whose accounts have been disabled by administrators can still log in, retaining full privileges. This vulnerability poses a significant risk as it allows unauthorized access to sensitive areas of the WordPress site, potentially leading to data breaches or malicious exploits.

Affected Version(s)

Disable Users 0 <= 1.0.5

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
