Hi,

The following vulnerabilities were published for 389-ds-base.

CVE-2026-11770[0]:
| A flaw was found in 389 Directory Server. An unauthenticated remote
| attacker can inject LDAP search filters into the CleanAllRUV
| replication status-check extended operation. Because the handler
| performs the search against cn=config with elevated replication
| plugin privileges and returns a boolean match result, the attacker
| can extract sensitive server configuration metadata, including
| replication bind DNs and password storage scheme information.


CVE-2026-15722[1]:
| A stack buffer overflow flaw was found in 389 Directory Server
| (389-ds-base). The get_ruvelement_from_berval() function in
| repl5_ruv.c copies digit characters from a network-supplied RUV
| berval into a fixed 16-byte stack buffer without bounds checking. A
| remote unauthenticated attacker can crash the LDAP server by sending
| a crafted StartNSDS50ReplicationRequest extended operation
| containing a replica ID field with more than 16 digit characters.
| The overflow occurs during payload decoding, before any
| authorization check. Stack protectors limit impact to denial of
| service.


If you fix the vulnerabilities please also make sure to include the
CVE (Common Vulnerabilities & Exposures) ids in your changelog entry.
