Lifecycle Timeline
2DescriptionCVE.org
OpenClaw Feishu tools (npm package @openclaw/feishu) in versions <= 2026.6.6 could ignore per-account disablement. A lower-trust caller or a configured input path could perform actions that should have required a stronger authorization or policy check, resulting in unauthorized operations. The issue is fixed in version 2026.6.9. Impact depends on the operator's configuration and whether lower-trust input can reach the affected feature.

AnalysisAI
Authorization bypass in the @openclaw/feishu npm package (versions <= 2026.6.6) allows a lower-trust caller - or attacker-influenced input reaching a configured input path - to perform Feishu (Lark) actions that should have required stronger authorization, because per-account disablement can be ignored. Authenticated remote attackers can trigger unauthorized operations affecting confidentiality and integrity; no public exploit has been identified at time of analysis, and the flaw is fixed in version 2026.6.9. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the OpenClaw deployment expose the @openclaw/feishu tools such that either (1) a lower-trust caller who holds some existing privilege (CVSS PR:L, so not fully unauthenticated) can invoke a Feishu action that a per-account disablement was meant to block, or (2) a configured input path carries lower-trust/attacker-influenced input into the affected feature. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 4.0 score is 8.6 (High) with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N, meaning network-reachable, low complexity, but requiring some existing privilege (PR:L) and yielding high confidentiality and integrity impact with no availability impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | In a deployment where OpenClaw exposes Feishu tools to multiple callers, an attacker holding a low-trust account (whose access to a sensitive Feishu action was supposedly disabled) invokes that action anyway, because the authorization check is skipped on that path, and performs unauthorized operations such as reading or modifying Feishu data. Alternatively, an attacker who can influence a configured input path feeds crafted input that reaches the affected feature to trigger the same unauthorized action. … |
| Remediation | Upgrade the @openclaw/feishu npm dependency to version 2026.6.9 or later, which contains the fix (Vendor-released patch: 2026.6.9); pin the version in package.json and rebuild/redeploy so transitive installs cannot pull a vulnerable release. … Detailed patch versions, workarounds, and compensating controls in full report. |
