CVE-2026-54421: CWE-212 Improper Removal of Sensitive Information Before Storage or Transfer in OpenStack Ironic
In OpenStack Ironic before 37.0.1, when applying a PATCH to update fields in volume properties the user is authorized for, Ironic can return unredacted sensitive information (such as iSCSI credentials). The PATCH outcome is a security issue; the POST outcome is not a security issue.
AI Analysis
Technical Summary
CVE-2026-54421 is a vulnerability in OpenStack Ironic prior to version 37.0.1. When a user with appropriate authorization applies a PATCH request to update fields in volume properties, the system may return sensitive information without redaction, including iSCSI credentials. This exposure occurs specifically during PATCH operations, while POST operations are not affected. The vulnerability is related to improper removal of sensitive information before transfer, categorized under CWE-212. The CVSS 3.1 base score is 6.8, indicating a medium severity with network attack vector, low attack complexity, high privileges required, no user interaction, and a confidentiality impact classified as high.
Potential Impact
Sensitive information such as iSCSI credentials may be exposed to authorized users during PATCH operations on volume properties. This could lead to unauthorized disclosure of credentials, potentially compromising confidentiality. There is no impact on integrity or availability. The vulnerability does not affect POST operations. No known exploits are reported in the wild.
Mitigation Recommendations
No official patch or remediation level has been published yet for this vulnerability. Patch status is not yet confirmed — check the OpenStack vendor advisory for current remediation guidance. Until a fix is available, limit PATCH operations on volume properties to trusted users only and monitor for any unusual access patterns related to volume property updates.
