Does this matter?

Lower severity and a low EPSS score (1.03%). Track it; it rarely justifies an emergency change on its own.

Description

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.
