{"data":{"id":"df556917-032c-4138-b5b7-48015ebff978","title":"TRACER: Trace-Regularized Training Against Indirect Prompt Injection","summary":"The TRACER paper shows that indirect prompt injection succeeds far more often when the malicious text sits in retrieved context (53%) than when it arrives as a follow-up message (18%). The authors propose TRACER, a channel-aware adversarial training method that combines an answer-anchored, evidence-gated reward with ATRC. On GSM8K with Qwen2.5-3B-Instruct, it cuts RAG-framed attack success from 65.5% to 6.1% while keeping 78-82% clean accuracy.","solution":"The source proposes TRACER, a channel-aware adversarial training method, as the defense. It does not describe a patch, fixed version, configuration change or workaround for a specific product.","labels":["security","research"],"sourceUrl":"https://arxiv.org/abs/2610.19133v1","publishedAt":"2026-10-13T20:03:37.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["prompt_injection"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Qwen2.5-3B-Instruct","Qwen2.5-7B"],"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":"2026-10-13T20:03:37.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","safety"],"aiComponentTargeted":"rag","llmSpecific":true,"classifierConfidence":0.97,"researchCategory":"preprint","atlasIds":["AML.T0051"]}}
