Summary
CVE-2026-32924 is a medium-severity Incorrect Authorization (CWE-863) vulnerability in Openclaw. Its CVSS base score is 6.9 (Medium).
Operationally, ranked at the 24th 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-25 (Reference Monitor) — 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.
OpenClaw versions prior to 2026.3.12 contain an authorization bypass vulnerability, tracked as CVE-2026-32924 and associated with CWE-863 (Incorrect Authorization). The issue arises in the handling of Feishu reaction events where the chat_type field is omitted, causing these events to be misclassified as peer-to-peer (p2p) conversations rather than group chats. This misclassification enables attackers to circumvent groupAllowFrom and requireMention protections that apply to reaction-derived events in group chat contexts. The vulnerability carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its network accessibility and high impact on confidentiality, integrity, and availability.
Attackers require no privileges (PR:N) and can exploit this remotely over the network with low complexity and no user interaction. By crafting and sending Feishu reaction events lacking the chat_type parameter, adversaries trigger the misclassification, allowing unauthorized actions in group chats that would otherwise be restricted by groupAllowFrom (limiting reactions to specific sources) and requireMention (mandating explicit mentions). Successful exploitation grants high-level access to sensitive operations, potentially enabling data exfiltration, modification, or disruption within affected OpenClaw deployments integrated with Feishu.
Mitigation details are outlined in the official advisories, including the OpenClaw GitHub security advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-m69h-jm2f-2pv8 and VulnCheck's analysis at https://www.vulncheck.com/advisories/openclaw-authorization-bypass-via-misclassified-reaction-events-in-feishu. Practitioners should upgrade to OpenClaw 2026.3.12 or later, where the misclassification logic has been corrected to properly enforce group chat protections.

Vulnerability Data
OpenClaw before 2026.3.12 contains an authorization bypass vulnerability where Feishu reaction events with omitted chat_type are misclassified as p2p conversations instead of group chats. Attackers can exploit this misclassification to bypass groupAllowFrom and requireMention protections in group chat reaction-derived events.

Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 directly requires correct enforcement of authorization decisions on every access request, structurally preventing incorrect checks.
AC-24 ensures access-control decisions are made and applied consistently, reducing the chance of an incorrect authorization result.
A reference monitor that is always invoked and tamper-proof forces every authorization decision through a verified, correct path.
Least-privilege assignments shrink the set of authorizations that must be checked correctly, limiting exposure to flawed checks.
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.
A.5.18's provisioning, revocation, review and adjustment of access rights (incl. before role changes/termination, with segregation and owner approval) directly stops incorrect authorization decisions from being exploitable in the vast majority of cases; the bounded remainder is incorrectness inside the authorization logic itself (e.g. flawed conditional or missing check) rather than rights that were wrongly granted.
A.8.3 directly mandates restricting access to information per policies via configuration, identity/group controls, isolation, and dynamic techniques that enforce correct authorization decisions, addressing most but not all slices of CWE-863 (e.g., remainder in non-access-decision authorization errors like timing or environmental factors).
Requiring consistency between access rights and classification plus formal approval steps ensures that the authorization logic correctly distinguishes between entities that should and should not be granted access.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
- No fine-grained STIG row for CWE-863, a class-level weakness, and none of its children carries one either.
