1) LDAP injection (CVE-ID: CVE-2026-31828)

CWE-ID: CWE-90 - Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to escalate privileges.

The vulnerability exists due to improper neutralization of special elements used in an LDAP query in the LDAP authentication adapter when constructing LDAP distinguished names and group search filters from user-supplied input. A remote user can supply a specially crafted authData.id value to escalate privileges.

The issue affects deployments that use the LDAP authentication adapter with group-based access control.
