CVE-2025-63291 is a medium-severity Authorization Bypass Through User-Controlled Key (CWE-639) vulnerability in Alteryx Alteryx Server. Its CVSS base score is 5.4 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Abuse Elevation Control Mechanism (T1548); ranked at the 15th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to AC-24 (Access Control Decisions) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Vulnerability Data
When processing API requests, the Alteryx server 2022.1.1.42654 and 2024.1 used MongoDB object IDs to uniquely identify the data being requested by the caller. The Alteryx server did not check whether the authenticated user had permission to access the specified…

MongoDB object ID. By specifying particlar MongoDB object IDs, callers could obtain records for other users without proper authorization. Records retrievable using this attack included administrative API keys and private studio api keys.

Mitigating Controls (NIST 800-53 r5) AI
Enforcing approved authorizations on every access request structurally stops a user-controlled key from reaching another user's data.
Requiring explicit access-control decisions on each request blocks unauthorized key-driven access.
Developer testing and evaluation can discover incorrect calls to privileged APIs before deployment.
Least-privilege restrictions limit the scope of data reachable even if a key check is bypassed.
Security engineering principles include correct use of privileged interfaces and safe invocation patterns that stop the weakness from being introduced.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Enforcing authorization policy and least privilege directly blocks user-controlled key tampering that bypasses access checks.
Logical access controls prevent unauthorized data access that results from missing authorization checks on object references.
Secure SDLC practices directly enforce correct usage of privileged APIs during development.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Security testing can detect missing authorization checks but does not prevent the weakness in production.
Information access restriction explicitly enforces that users may only retrieve data they are authorized to see, directly addressing user-controlled key bypass.
Access control policy directly requires enforcement of authorization rules that prevent unauthorized access via manipulated keys.
Managing access rights includes ensuring users can only access their own records and not bypass authorization by altering identifiers.
Restricting privileged utility programs limits the exposure of privileged APIs to misuse.
Privileged access rights control restricts what data each user may access, mitigating direct object reference attacks.
