An attacker can craft a serialized deepdiff.Delta that passes the deserializer whitelist and contains dunder attributes, which lets them reach other modules, classes and instances, enabling arbitrary attribute write and full RCE on self-hosted applications in their default configuration because the delta endpoint is enabled by default.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2024-5452","publishedAt":"2024-06-06T22:15:20.970Z","cveId":"CVE-2024-5452","cweIds":["CWE-915","CWE-913"],"cvssScore":"9.8","cvssSeverity":"critical","severity":"critical","attackType":["other"],"issueType":"vulnerability","affectedPackages":["lightning@< 2.3.3 (fixed: 2.3.3)"],"affectedPackageNames":["lightning"],"affectedPackageRefs":["pypi:lightning"],"affectedVendors":[],"affectedVendorsRaw":["PyTorch Lightning"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"pytorch-lightning remote code execution via deepdiff Delta input","headlinePromptVersion":"h1","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.26831,"epssCheckedAt":"2026-11-04T18:09:13.116Z","kevDateAdded":null,"advisoryAliases":["GHSA-cgwc-qvrx-rf7f"],"affectedPackagesSource":"ghsa","affectedPackagesCheckedAt":"2026-10-10T03:55:48.638Z","patchAvailable":true,"disclosureDate":null,"fixReleasedAt":"2024-07-08T20:47:54.133Z","daysToFix":32,"fixCheckedAt":"2026-10-29T21:45:52.308Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"lightning","fixedVersion":"2.3.3","matchedVersion":"2.3.3","fixReleasedAt":"2024-07-08T20:47:54.133Z","daysToFix":32,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-10-29T21:45:52.158Z"}]}}
