{"data":{"id":"18ae6cb5-aa61-445a-be22-8915f95ef421","title":"SEAL: Sealed Queries for Local Sanitization against Indirect Prompt Injection","summary":"SEAL, a method for sanitizing tool outputs against indirect prompt injection in local LLM agents, learns a soft prompt and scoring readout offline and uses a frozen task model. On AgentDojo it reduces attack success from 34.6% to 0.1% and raises joint task completion from 51.4% to 77.5%, using about 127 times fewer defense-related tokens than PISanitizer. The authors also report results on AgentDyn and a second backbone.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://arxiv.org/abs/2610.39758v1","publishedAt":"2026-10-29T10:11:51.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["prompt_injection"],"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":"2026-10-29T10:11:51.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity","confidentiality"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":"preprint","atlasIds":["AML.T0051"]}}
