What is CVE-2026-85530?

The GiveWP WordPress plugin prior to version 4.16.8.1 contains a vulnerability that mishandles the normalization of donor email addresses. This inconsistency allows unauthorized users to be misidentified as legitimate donors, potentially granting them the ability to alter the WordPress password of any linked user account, including administrative accounts. This flaw poses a significant risk as it enables a breach of user confidentiality and could lead to critical account takeovers if exploited.

Affected Version(s)

GiveWP 4.16.6 < 4.16.8.1

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.
