Security Bulletin
Summary
Vault Enterprise's identity entity batch-delete endpoint is vulnerable to a cross-namespace authorization bypass that may allow an authenticated caller in one namespace to permanently delete the storage backing of entities belonging to another namespace. This vulnerability (CVE-2026-14886) is fixed in Vault Enterprise 2.0.4, 1.21.9, 1.20.14 and 1.19.20.
Vulnerability Details
CVEID: CVE-2026-14886
DESCRIPTION: The batch-delete handler checked the namespace of each requested entity to determine whether it should be removed from Vault's in-memory identity database, but it did not apply that same namespace check before removing the entity’s underlying storage. Because entity storage is shared across namespaces and organized only by entity ID, a caller could submit the ID of an entity belonging to a different namespace and cause its storage to be deleted, even though the entity remained visible in memory until the next restart or reload. Once the identity store reloaded from storage, the affected entity was permanently lost. The issue requires an authenticated caller with access to the batch-delete endpoint in some namespace; it does not require access to the namespace that owns the target entity. Vault Community Edition is not affected because it does not include namespaces.

According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
