PR:L reflects that exploitation requires a pre-existing pending bootstrap token, implying a prior low-privilege relationship; AC:H captures the narrow approval-window timing dependency.

OpenClaw before 2026.5.12 contains a bootstrap token replay vulnerability allowing callers with pending token access to reuse tokens with broader requested scopes. Attackers can replay bootstrap tokens before approval to escalate pairing authority beyond intended scope limits.
AnalysisAI
Bootstrap token replay in OpenClaw before version 2026.5.12 permits callers holding a pending bootstrap token to resubmit that token with a broader scope than originally requested, bypassing intended pairing authority limits. The flaw, rooted in incorrect privilege assignment (CWE-266), exploits the gap between token issuance and administrative approval to escalate pairing access. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must already hold a valid pending bootstrap token, meaning they must have completed the initial pairing-request step with the target OpenClaw instance - fully external unauthenticated attackers without a pending token cannot exploit this flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 2.3 accurately reflects a low-risk vulnerability. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has legitimately initiated a pairing request with an OpenClaw instance obtains a pending bootstrap token and, before an administrator approves or rejects it, replays that token against the API with a crafted request specifying a broader set of scopes than originally submitted. If the server processes the replayed request within the open approval window without re-validating the originally bound scope, the attacker's pairing authority is elevated beyond the intended limit. … |
| Remediation | The primary fix is to upgrade OpenClaw to version 2026.5.12 or later, per the vendor GitHub Security Advisory GHSA-9v8j-9c9g-w66c (https://github.com/openclaw/openclaw/security/advisories/GHSA-9v8j-9c9g-w66c). … Detailed patch versions, workarounds, and compensating controls in full report. |
