This medium-severity CVE scores 4.3 under the CNA's CVSS (NVD's own analysis pending). EPSS exploit probability: 1.0%, top 41% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
