A flaw was found in Data Science Pipelines (DSP). (CVE-2026-18621)
A vulnerability in Data Science Pipelines (DSP) allows an attacker with namespace editor privileges to bypass security controls by submitting a malicious Argo Workflow through the V1 API path. This flaw enables the API server to create pods with elevated privileges, effectively acting as a 'confused deputy' on behalf of the attacker. Successful exploitation grants node-root access, allowing arbitrary code execution and full control over the underlying node. The vulnerability is tracked as CVE-2026-18621 with a CVSS score of 7.6 (high severity).
AI Analysis
Technical Summary
CVE-2026-18621 is a security flaw in Data Science Pipelines (DSP) where an attacker possessing namespace editor privileges can bypass security hardening mechanisms by submitting a crafted Argo Workflow via the V1 API path. This causes the API server to create pods with elevated privileges, acting as a 'confused deputy' and granting the attacker node-root access. This access enables arbitrary code execution and full control over the node hosting the pods. The vulnerability is associated with CWE-266 (Incorrect Privilege Assignment).
Potential Impact
Exploitation of this vulnerability allows an attacker with namespace editor privileges to escalate privileges to node-root level, enabling arbitrary code execution and full control over the underlying node. This can lead to complete compromise of the affected system.
Mitigation Recommendations
The vendor (Red Hat) has released updated images for Red Hat OpenShift AI that address this vulnerability. Users are advised to upgrade to the fixed versions as documented in the Red Hat advisory and follow the official upgrade instructions to fully apply the errata update. Patch status is confirmed by the vendor advisory. No indication of temporary fixes or workarounds is provided, so applying the official update is the recommended mitigation.
