Summary

CVE-2026-0945 is a high-severity Privilege Defined With Unsafe Actions (CWE-267) vulnerability in Role Delegation Project Role Delegation. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Access Token Manipulation (T1134); ranked at the 13th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-6 (Least Privilege) and AC-5 (Separation of Duties) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2026-0945 is a Privilege Defined With Unsafe Actions vulnerability in the Drupal Role Delegation module that allows privilege escalation. This issue affects Role Delegation versions from 1.3.0 up to but not including 1.5.0. The vulnerability is associated with CWE-267 and has a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

An attacker with low privileges can exploit this vulnerability remotely over the network with low complexity and no user interaction required. Successful exploitation enables high-impact disruption to confidentiality, integrity, and availability within the unchanged scope, facilitating privilege escalation.

The Drupal security advisory SA-CONTRIB-2026-002, available at https://www.drupal.org/sa-contrib-2026-002, provides further details on mitigation steps.

Mitigating Controls (NIST 800-53 r5) AI

AC-6 Least Privilege good match

Least privilege directly requires that privileges grant only the minimal actions needed, preventing definition of overly broad privileges that include unintended unsafe operations.

AC-5 Separation of Duties partial match

Separation of duties splits high-risk actions across multiple privileges so that no single privilege can perform the full unsafe sequence.

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.

PR.AA-05 mostly match
prevents

Defining and enforcing least-privilege permissions directly reduces the chance that a privilege permits unintended unsafe actions.

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.

A.8.18 Use of privileged utility programs mostly match
mitigates

Use of privileged utility programs restricts dangerous tools but does not address unsafe actions within assigned privileges.

A.5.15 Access control partial match
mitigates

Access control policy can limit unsafe privilege use but does not define safe actions for each privilege.

A.5.18 Access rights partial match
degrades

Access rights assignment can restrict privileges to intended actions, yet does not guarantee the privilege itself is safe.

A.5.3 Segregation of duties partial match
mitigates

Segregation of duties reduces risk of unsafe actions by splitting privileges but does not address unsafe privilege definitions.

A.8.2 Privileged access rights partial match
mitigates

Privileged access rights control can restrict unsafe privileges, yet does not ensure the privilege definition itself is safe.

A.8.25 Secure development life cycle partial match
mitigates

Secure development lifecycle can catch unsafe privilege definitions during design but does not prevent them at runtime.
