Information disclosure in persistent watchers handling in Apache ZooKeeper due to missing ACL check. It allows an attacker to monitor child znodes by attaching a persistent watcher (addWatch command) to a parent which the attacker has already access to. ZooKeeper server doesn't do ACL check when the persistent watcher is triggered and as a consequence, the full path of znodes that a watch event gets triggered upon is exposed to the owner of the watcher. It's important to note that only the path is exposed by this vulnerability, not the data of znode, but since znode path can contain sensitive information like user name or login ID, this issue is potentially critical. Users are recommended to upgrade to version 3.9.2, 3.8.4 which fixes the issue.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

Successful attacks of this     vulnerability can result in takeover of these products. (CVE-2025-48734)

  - Vulnerability in the Oracle Applications DBA product of Oracle E-Business Suite (component: ADPatch).
    Supported versions that are affected are 12.2.3-12.2.15. Difficult to exploit vulnerability allows high     privileged attacker with network access via HTTP to compromise Oracle Applications DBA. Successful attacks     require human interaction from a person other than the attacker and while the vulnerability is in Oracle     Applications DBA, attacks may significantly impact additional products (scope change). Successful attacks     of this vulnerability can result in takeover of Oracle Applications DBA. (CVE-2026-22011)

  - Vulnerability in the Oracle Enterprise Command Center Framework product of Oracle E-Business Suite     (component: ECC Core (Netty)). The supported version that is affected is 15.0. Easily exploitable     vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Enterprise     Command Center Framework. Successful attacks of this vulnerability can result in unauthorized ability to     cause a hang or frequently repeatable crash (complete DOS) of Oracle Enterprise Command Center Framework.
    (CVE-2025-58057)

  - Vulnerability in the Oracle HCM Common Architecture product of Oracle E-Business Suite (component:
    Knowledge Integration). Supported versions that are affected are 12.2.3-12.2.15. Easily exploitable     vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle HCM Common     Architecture. Successful attacks of this vulnerability can result in unauthorized update, insert or delete     access to some of Oracle HCM Common Architecture accessible data as well as unauthorized read access to a     subset of Oracle HCM Common Architecture accessible data. (CVE-2026-34297)
