{"data":{"id":"72106efa-545a-4ef8-9270-1297bdfcc96f","title":"Understanding Backdoor Attacks in Scene Graph Generation via Global Context Pathway","summary":"This paper studies training-time backdoor attacks on Scene Graph Generation (SGG), focusing on the explicit global context pathway in recent architectures. The authors instantiate an attack that selectively corrupts relations involving a designated object category, and evaluate it on Visual Genome with open-vocabulary and closed-set SGG models using a three-axis protocol. Mechanistic analysis finds the global context pathway is a major carrier of the backdoor effect. Replacing the poisoned global context representation with its clean counterpart at inference cuts attack success by 100% for the OvSGTR family and 97% for RelationFormer.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://arxiv.org/abs/2611.04379v1","publishedAt":"2026-11-03T06:05:22.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["other"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["OvSGTR","RelationFormer","Visual Genome"],"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":"2026-11-03T06:05:22.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":"preprint","atlasIds":null}}
