When a tool is invoked, the library validates the initial URL but then follows redirects without re-checking where they lead, allowing an attacker to redirect the request to internal services like cloud metadata endpoints (systems that store sensitive configuration data) and steal the response. This is a form of SSRF (server-side request forgery, where an attacker tricks a server into making requests to unintended targets).","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-9qhg-99ww-9mqc","publishedAt":"2026-08-25T15:48:51.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["supply_chain"],"issueType":"vulnerability","affectedPackages":["utcp-http@<= 1.1.3 (fixed: 1.1.4)"],"affectedVendors":["LangChain"],"affectedVendorsRaw":["utcp-http","UTCP","Universal Tool Calling Protocol"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":true,"disclosureDate":"2026-08-25T15:48:51.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":null,"atlasIds":null}}
