CVE-2026-25560Network attack vector

Unauthenticated LDAP query manipulation via unescaped username

Published Feb 7, 2026 · Updated Feb 7, 2026

LDAP injection in WeKan before 8.19 allows remote attackers to manipulate authentication queries through a crafted username. The LDAP class in packages/wekan-ldap/server/ldap.js interpolates the unescaped username into search filters, custom filter placeholders, and user DNs used for binding. Reachability requires LDAP authentication to be enabled; the malformed query can change directory search or bind semantics, while authentication bypass is not established.
