Affected versions are openclaw (npm) up to and including 2026.2.24; core CLI and gateway onboarding paths are not affected. Exploitation required obtaining both the OAuth authorization artifacts and the exposed state values during that flow.","solution":"Fixed in 2026.2.25. OpenClaw removed Anthropic OAuth sign-in from macOS onboarding and now supports setup-token-only Anthropic subscription auth in this path.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-6g25-pc82-vfwp","publishedAt":"2026-03-03T00:39:40.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"medium","severity":"medium","attackType":["other"],"issueType":"vulnerability","affectedPackages":["openclaw@<= 2026.2.24 (fixed: 2026.2.25)"],"affectedPackageNames":["openclaw"],"affectedPackageRefs":["npm:openclaw"],"affectedVendors":["Anthropic"],"affectedVendorsRaw":["OpenClaw","Anthropic OAuth","Claude"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"epssCheckedAt":null,"kevDateAdded":null,"advisoryAliases":["GHSA-6g25-pc82-vfwp"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":null,"fixReleasedAt":"2026-02-26T04:16:34.010Z","daysToFix":-5,"fixCheckedAt":"2026-10-29T21:40:20.618Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"openclaw","fixedVersion":"2026.2.25","matchedVersion":"2026.2.25","fixReleasedAt":"2026-02-26T04:16:34.010Z","daysToFix":-5,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:40:20.472Z"}]}}
