DescriptionCVE.org

OpenClaw versions 2026.4.12-beta.1 before 2026.6.6 contain a missing-authorization vulnerability in the MS Teams message actions feature. When the affected feature is enabled and reachable, a lower-trust caller or a configured input path can perform actions that should have required a stronger authorization or policy check. Practical impact depends on the operator's configuration and whether lower-trust input can reach that path. The issue is fixed in 2026.6.6.

AnalysisAI

Missing authorization controls in OpenClaw's MS Teams message actions feature permit a low-privilege authenticated caller to invoke operations that should require elevated permissions or policy checks, resulting in high integrity impact (VI:H per the CVSS 4.0 vector) on affected deployments. The flaw spans versions 2026.4.12-beta.1 through 2026.6.5, and practical severity is configuration-dependent - exploitation is gated on the MS Teams feature being enabled and reachable. …

Vulnerability AssessmentAI

Exploitation Exploitation requires three concurrent conditions: (1) the MS Teams message actions feature must be explicitly enabled in the OpenClaw deployment - the vulnerability is not present in configurations where this feature is disabled; (2) the message actions endpoint must be network-reachable by the attacker (AV:N per CVSS 4.0); and (3) the attacker must hold at least low-privilege authenticated access to the system (PR:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 6.0 (Medium) reflects the combination of a low-privilege network vector (AV:N/PR:L) and high integrity impact (VI:H) against the constraining factor of specific attack requirements (AT:P). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated low-privilege user or automated integration account with network access to an OpenClaw deployment that has the MS Teams message actions feature enabled sends a crafted message action request directly to the vulnerable endpoint, bypassing the expected authorization check. Because the authorization gate is missing, OpenClaw processes the request as if it originated from a higher-trust caller, allowing the attacker to modify data or trigger privileged operations. …
Remediation Upgrade to OpenClaw 2026.6.6, the vendor-confirmed fixed release per the GitHub security advisory (https://github.com/openclaw/openclaw/security/advisories/GHSA-p5xh-frrh-cmgj). … Detailed patch versions, workarounds, and compensating controls in full report.
