Response-Guided Semantic Probing and Adaptive Routing for Transferable Attacks on Black-Box MLLMs","summary":"VISTA is a black-box attack framework that finds semantically vulnerable image regions in multimodal LLMs using only their text responses, without gradients, logits, parameters or internal representations. It builds an Uncertainty-Based Multimodal Behavior (UBMB) map from response drift, conflict, misleading and semantic shifts, then routes perturbations to those regions. Across GPT-5, Gemini-3.5-Flash and Claude Sonnet 4.6 it reports up to 97 % attack success rate at PSNR above 30 dB, and VISTA-Proxy reaches up to 93 % without querying the final victim model.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://arxiv.org/abs/2610.38013v1","publishedAt":"2026-10-27T22:09:51.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["model_evasion"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["OpenAI","Google","Anthropic"],"affectedVendorsRaw":["GPT-5","Gemini-3.5-Flash","Claude Sonnet 4.6"],"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":"2026-10-27T22:09:51.000Z","fixReleasedAt":null,"daysToFix":null,"fixCheckedAt":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity","safety"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":"preprint","atlasIds":null}}
