+### CVE-2026-24308: Sensitive information disclosure in client configuration
handling
+
+Severity: important
+
+Affected versions:
+
+- Apache ZooKeeper (org.apache.zookeeper:zookeeper) 3.9.0 through 3.9.4
+- Apache ZooKeeper (org.apache.zookeeper:zookeeper) 3.8.0 through 3.8.5
+
+Description:
+
+Improper handling of configuration values in ZKConfig in Apache ZooKeeper
3.8.5 and 3.9.4 on all platforms allows an attacker to expose sensitive
information stored in client configuration in the client's logfile.
Configuration values are exposed at INFO level logging rendering potential
production systems affected by the issue. Users are recommended to upgrade to
version 3.8.6 or 3.9.5 which fixes this issue.

+- Apache ZooKeeper (org.apache.zookeeper:zookeeper) 3.8.0 through 3.8.5
+
+Description:
+
+Hostname verification in Apache ZooKeeper ZKTrustManager falls back to reverse
DNS (PTR) when IP SAN validation fails, allowing attackers who control or spoof
PTR records to impersonate ZooKeeper servers or clients with a valid
certificate for the PTR name. It's important to note that attacker must present
a certificate which is trusted by ZKTrustManager which makes the attack vector
harder to exploit. Users are recommended to upgrade to version 3.8.6 or 3.9.5,
which fixes this issue by [...]
