Its trusted domain check for WebFetch requests used startsWith(), so a domain such as modelcontextprotocol.io.example.com passed validation as if it were modelcontextprotocol.io. This could let an attacker trigger automatic requests to attacker-controlled domains without user consent, potentially leading to data exfiltration.","solution":"Fixed in version 1.0.111.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-24052","publishedAt":"2026-02-03T21:16:13.073Z","cveId":"CVE-2026-24052","cweIds":["CWE-601"],"cvssScore":"7.4","cvssSeverity":"high","severity":"high","attackType":["data_extraction"],"issueType":"vulnerability","affectedPackages":["@anthropic-ai/claude-code@< 1.0.111 (fixed: 1.0.111)"],"affectedPackageNames":["@anthropic-ai/claude-code"],"affectedPackageRefs":["npm:@anthropic-ai/claude-code"],"affectedVendors":["Anthropic"],"affectedVendorsRaw":["Claude Code"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Claude Code WebFetch trusted domain check bypass via startsWith validation","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00432,"epssCheckedAt":"2026-11-04T18:09:14.469Z","kevDateAdded":null,"advisoryAliases":["GHSA-vhw5-3g5m-8ggf"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:51:04.686Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2025-09-10T22:16:23.609Z","daysToFix":-146,"fixCheckedAt":"2026-10-29T21:41:52.517Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"plugin","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"npm","name":"@anthropic-ai/claude-code","fixedVersion":"1.0.111","matchedVersion":"1.0.111","fixReleasedAt":"2025-09-10T22:16:23.609Z","daysToFix":-146,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:41:52.367Z"}]}}
