CVE-2026-42568

Status: DeferredMedium (4.3)—

Yamcs is a mission control framework. Prior to versions 5.13.0 and 5.12.7, an LDAP injection vulnerability exists in `org.yamcs.security.LdapAuthModule` when constructing search filters. The username parameter is inserted directly into the LDAP filter without proper RFC 4515 escaping. Versions 5.13.0 and 5.12.7 patch the issue.

CVSS
