MITRE ATT&CK
1 technique across 1 tactic: Privilege Escalation The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | Exploitation requires the attacker to already hold exec-authorized user credentials within OpenClaw (confirmed by PR:L in the CVSS 4.0 vector - unauthenticated exploitation is not possible). The Slack plugin must be deployed and operator-configured with approval splits; the CVSS 4.0 AT:P metric explicitly encodes this prerequisite. Exploitation is further limited by: (1) the impact ceiling of VC:L only - no integrity or availability impact is achievable through this path; (2) the need for an active Slack plugin integration, which is not a default or universal deployment; and (3) the attacker must already be a recognized user within the system with at least exec-tier permissions, making this an insider-threat or account-compromise scenario rather than an opportunistic external attack. Organizations not using the Slack plugin, or using it without approval splits, are not exposed. |
| Impact | Multiple risk signals converge on a low-priority assessment. The CVSS 4.0 base score of 2.3 is driven by three compounding limiters: AT:P (specific prerequisites required), PR:L (attacker must already hold exec-level authentication), and a constrained impact profile of VC:L/VI:N/VA:N - meaning only limited confidentiality exposure on the vulnerable system, with no integrity or availability impact. This is inconsistent with a traditional privilege escalation that grants elevated system access; the 'escalation' here is confined to the approval workflow itself. No EPSS data was provided. The vulnerability is not listed in CISA KEV and no POC has been identified. Real-world risk is essentially an insider-threat or privilege-abuse scenario within organizations running OpenClaw with Slack plugin approval splits - the attack surface is not reachable in default or Slack-plugin-less deployments. The tags 'Authentication Bypass' and 'Privilege Escalation' from VulnCheck are accurate but may overstate severity without the configuration context. |
| Exploit ScenarioDerived | An insider or compromised account holding exec-authorized user status in OpenClaw navigates to the Slack plugin approval interface and submits a resolution request through the exec approver gate for a plugin action they are not operator-configured to approve. The system incorrectly authorizes the resolution, allowing the user to approve plugin actions outside the operator-defined split - potentially triggering plugin behaviors that were intended to require multi-party sign-off. No public POC has been identified at time of analysis. |

Alert meAnalysisAIv1 – May 29, 2026
Privilege escalation in OpenClaw's Slack plugin approval workflow allows authenticated users holding limited exec permissions to bypass operator-configured approval splits by resolving plugin approvals through the exec approver gate - approving actions outside their intended authorization boundary. All OpenClaw versions before 2026.5.12 are affected when the Slack plugin is deployed with approval split configurations. No public exploit code has been identified and this vulnerability is not listed in CISA KEV; the CVSS 4.0 score of 2.3 accurately reflects its narrow real-world impact, constrained by prerequisites and a low impact ceiling.
RemediationAI
Upgrade to OpenClaw 2026.5.12 or later, which resolves the incorrect authorization in the exec approver gate per the vendor advisory at https://github.com/openclaw/openclaw/security/advisories/GHSA-wv26-j37q-2g7p. For deployments that cannot immediately upgrade, restrict exec approval permissions to only fully trusted personnel, which eliminates the risk surface by ensuring no potentially malicious insider holds exec-level authorization. Operators should also audit existing Slack plugin approval split configurations to verify that sensitive plugin actions require approval from roles beyond the exec gate alone - adding a secondary, independent approval role as a workaround trade-off (increased approval friction in exchange for authorization boundary enforcement). Note that disabling the Slack plugin entirely removes the attack surface without affecting non-Slack functionality.

Technical ContextAI · show details
OpenClaw implements a multi-party authorization model for Slack plugin actions using configurable 'approval splits' - operator-defined gates that distribute resolution authority among distinct roles to enforce separation of duties. The exec approver gate is one such gate, intended for a specific tier of approval authority. CWE-863 (Incorrect Authorization) describes the root cause: the system incorrectly evaluates whether an exec-authorized user holds sufficient rights to resolve approvals through that gate, failing to enforce the operator-intended split. The CVSS 4.0 AT:P (Attack Requirements: Present) metric directly encodes that the vulnerability is only reachable under a specific deployment configuration - Slack plugin active with approval splits configured. No CPE strings were provided in the available intelligence; affected scope is derived from the vendor advisory and description alone.

Lifecycle Timeline
1DescriptionCVE.org
OpenClaw before 2026.5.12 contains a privilege escalation vulnerability in Slack plugin approvals that allows exec-authorized users to resolve plugin approvals through the exec approver gate. Attackers with limited exec approval permissions can bypass intended approval splits to approve plugin actions outside operator configuration.
