They compared LLM Guard, Vigil, and Rebuff, finding that the canary word-based detection in Vigil and Rebuff was weak against these attacks, and that Rebuff's secondary model-based technique had an evasion weakness. Vigil was found optimal when a minimal false positive rate is required, and Rebuff when the highest detection rate is needed.","solution":"The authors propose improvements for the canary word-based detection techniques in Vigil and Rebuff, and they proposed a mitigation for the evasion weakness in Rebuff's secondary model-based technique. The specific details of these improvements and mitigation are not given in the source text.","labels":["security","research"],"sourceUrl":"https://doi.org/10.1007/s10207-026-01338-7","publishedAt":"2026-10-03T00:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["prompt_injection"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["LLM Guard","Vigil","Rebuff"],"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":"2026-10-03T00:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality"],"aiComponentTargeted":"inference","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":"peer_reviewed","atlasIds":null}}
