CVE-2026-6356 is a critical-severity Insufficient Granularity of Access Control (CWE-1220) vulnerability in Augmentt Augmentt. Its CVSS base score is 9.6 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Services File Permissions Weakness (T1574.010); ranked at the 21th 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-24 (Access Control Decisions) and AC-3 (Access Enforcement) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-6356 is a privilege escalation vulnerability in a web application that allows standard users to elevate their privileges to super administrator levels through parameter manipulation. This flaw enables attackers to access and modify sensitive information. It carries a CVSS v3.1 base score of 9.6 (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:N) and is associated with CWE-1220. The vulnerability was published on 2026-04-22.
Standard users with low privileges (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low attack complexity and no user interaction required. Successful exploitation changes the scope (S:C) and results in high impacts to confidentiality and integrity (C:H/I:H), allowing attackers to gain super administrator access and manipulate sensitive data, while availability remains unaffected (A:N).

Mitigating Controls (NIST 800-53 r5) AI
Least privilege explicitly demands that only the minimum necessary accesses are granted, eliminating the broad permissions that define this weakness.
AC-24 requires access decisions to be applied precisely and unambiguously to every request, structurally blocking insufficiently granular policies.
AC-3 requires enforcement of authorizations according to policy, directly compelling sufficiently granular rules so broad allowances cannot be introduced.
AC-4 enforces approved information flows with explicit source/destination rules, preventing overly coarse access policies from being deployed.
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.
PR.IR-01's segmentation + zero-trust rules directly enforce minimum-necessary access at network boundaries, removing most instances of overly broad policy; CWE-1220 can still exist in application-layer or intra-segment controls that this single outcome does not address.
PR.PS-06's general SDLC practices can surface granularity issues during design/review (partial prevention) but do not specifically target access-control policy breadth, so they remove only part of CWE-1220's risk.
CWE-1220 permits unauthorized access to sensitive assets but neither prevents nor impairs the delivery of adverse-event information to authorized recipients.

Directly requires information-access restriction at the level of individual assets and operations, addressing the granularity gap.
Establishes the overarching access-control policy whose granularity directly determines whether the weakness exists.
Defines the assignment and review of access rights; insufficient granularity in those rights is the root of CWE-1220.
Specifies management of privileged access rights, where overly broad privileges are a common manifestation of the weakness.
Limits use of privileged utilities; overly coarse access rules can still allow unauthorized utility access.
