A crafted tar archive containing a symlink, extracted in _unpack_bundle, lets an attacker read any file by absolute path, such as Langflow's secret_key used to sign JWTs. With that key an attacker can forge tokens for any user and execute code through a Python Interpreter node. Any user ingesting untrusted data with these components is affected, and the code execution risk depends on the scenario.","solution":"Fixed in 1.9.2 via PR #12945. BaseFileComponent._unpack_bundle now rejects symlink and hardlink members and any non-regular entries during TAR extraction, with additional symlink filtering during directory recursion and after extraction. Upgrade to 1.9.2 or later.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-ccv6-r384-xp75","publishedAt":"2026-06-19T21:18:24.000Z","cveId":"CVE-2026-55447","cweIds":null,"cvssScore":null,"cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["langflow@< 1.9.2 (fixed: 1.9.2)"],"affectedPackageNames":["langflow"],"affectedPackageRefs":["pypi:langflow"],"affectedVendors":[],"affectedVendorsRaw":["Langflow","Docling","Docling Serve","NVIDIA Retriever Extraction","Unstructured API","Chroma DB"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00662,"epssCheckedAt":"2026-11-04T12:08:34.339Z","kevDateAdded":null,"advisoryAliases":["GHSA-ccv6-r384-xp75"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-06-19T21:18:24.000Z","fixReleasedAt":"2026-05-01T18:57:22.383Z","daysToFix":-49,"fixCheckedAt":"2026-10-29T21:34:07.696Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.93,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"langflow","fixedVersion":"1.9.2","matchedVersion":"1.9.2","fixReleasedAt":"2026-05-01T18:57:22.383Z","daysToFix":-49,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:34:07.552Z"}]}}
