CVE-2026-115358 Details
Description
OpenBao before 2.6.3 contains an information disclosure vulnerability that allows attackers to leak sensitive data into audit logs by sending malformed plugin parameters. Attackers can submit requests with malformed TypeKVPair or TypeHeader field values, causing error messages containing sensitive input to be recorded in audit logs.
A vulnerability allowing information disclosure has been identified in OpenBao versions prior to 2.6.3. This issue arises from the improper handling of malformed plugin parameters, specifically in the TypeKVPair and TypeHeader fields. When such malformed data is processed, error messages containing sensitive information are inadvertently logged in the audit logs, creating a potential leakage of confidential data.
Users can upgrade to OpenBao versions 2.6.3 or 2.7.1 to address this vulnerability. Instructions for updating can be found in the OpenBao GitHub repository.
