Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The openam-auth-msisdn Maven package, versions before 16.1.1, is vulnerable to an LDAP injection flaw in its MSISDN authentication module. An unauthenticated remote attacker can exploit this in the default trusted gateway configuration to obtain an arbitrary OpenAM session without a password. Upgrade to version 16.1.1, which fixes the issue.
