OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including secrets, certificates, and keys. OpenBao before v2.3.0 may leak sensitive information in logs when processing malformed data. This is separate from the earlier HCSEC-2025-09 / CVE-2025-4166. This issue has been fixed in OpenBao v2.3.0 and later. Like with HCSEC-2025-09, there is no known workaround except to ensure properly formatted requests from all clients.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including
    secrets, certificates, and keys. OpenBao before v2.3.0 may leak sensitive information in logs when
    processing malformed data. This is separate from the earlier HCSEC-2025-09 / CVE-2025-4166. This issue has
    been fixed in OpenBao v2.3.0 and later. Like with HCSEC-2025-09, there is no known workaround except to
    ensure properly formatted requests from all clients. (CVE-2025-52893)

  - OpenBao exists to provide a software solution to manage, store, and distribute sensitive data including
    secrets, certificates, and keys. OpenBao before v2.3.0 allowed an attacker to perform unauthenticated,
    unaudited cancellation of root rekey and recovery rekey operations, effecting a denial of service. In
    OpenBao v2.2.0 and later, manually setting the configuration option
    `disable_unauthed_rekey_endpoints=true` allows an operator to deny these rarely-used endpoints on global
    listeners. A patch is available at commit fe75468822a22a88318c6079425357a02ae5b77b. In a future OpenBao
    release communicated on OpenBao's website, the maintainers will set this to `true` for all users and
    provide an authenticated alternative. As a workaround, if an active proxy or load balancer sits in front
    of OpenBao, an operator can deny requests to these endpoints from unauthorized IP ranges. (CVE-2025-52894)
