CVE-2026-100584: OpenClaw is an npm-distributed agent runtime. In versions >= 2026.2.26 and < 2026.7.1, PowerShell command analysis on Windows hosts running in exec allowlist mode could approve an exact executable resolved from PATH but subsequently execute a same-named executable located in the workspace directory. If lower-trust content can place an executable with an approved basename into an agent-writable workspace and steer an approved PowerShell command that uses a bare executable name, OpenClaw may run the workspace file instead of the allowlisted path, executing arbitrary code with the privileges of the Gateway or node-host user. The issue does not require replacement of the approved executable itself. Version 2026.7.1 contains a fix; as a workaround, avoid bare executable names in approved PowerShell commands and keep executable files out of agent-writable workspaces.
The exploitability of CVE-2026-100584 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
This vulnerability, CVE-2026-100584, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-100584, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-100584, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
