{"data":{"id":"6a89a6d2-1208-494f-87ff-2b0fefc5acbe","title":"Explainability-Guided Untargeted Attacks on Knowledge Graph Embedding","summary":"PathAttack is a path-based, explainable untargeted attack framework for knowledge graph embedding (KGE), where an adversary deletes key triplets or injects malicious triplets to degrade learned representations. It replaces predefined target sets with a triplet discovery approach that combines selection across different KGE model types, and weights multi-hop relational paths for adversarial deletion and addition. Experiments on FB15k-237, WN18RR, and OGBL-WikiKG2 show improved effectiveness, including a 5% gain on WN18RR, and scalability to KGs with millions of entities.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"http://ieeexplore.ieee.org/document/11503437","publishedAt":"2026-05-01T13:17:54.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["other"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":[],"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":null,"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":null,"disclosureDate":"2026-05-01T13:17:54.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.85,"researchCategory":"peer_reviewed","atlasIds":null}}
