{"data":{"id":"38ce3e65-3b4c-426e-9a97-f76ffcc49fcc","title":"TraceRouter++: Causal Semantic Routing Realignment via Optimal Transport","summary":"TraceRouter++ is a routing-level safety framework for large foundation models that traces causal routing pathways activated by harmful inputs and realigns their unsafe activation states. It uses sparse autoencoders, feature influence scores, and a constrained optimal transport soft realignment instead of rigid neuron suppression. The authors report improved adversarial robustness and a favorable safety-utility trade-off across LLMs, MLLMs, and diffusion models.","solution":"N/A -- no mitigation discussed in source.","labels":["research","safety"],"sourceUrl":"https://arxiv.org/abs/2611.04878v1","publishedAt":"2026-11-03T13:30:34.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["jailbreak"],"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":"2026-11-03T13:30:34.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["safety"],"aiComponentTargeted":"model","llmSpecific":false,"classifierConfidence":0.95,"researchCategory":"preprint","atlasIds":["AML.T0054"]}}
