{"data":{"id":"10ce9c49-ca4a-433b-b901-afbb5be98242","title":"Visual Memory Attacks Can Persist Through The KV Cache","summary":"Researchers show that adversarial images can plant a backdoor in a vision-language model that persists after the image is masked from attention. The persistent variant, Persistent Visual Memory Injection (P-VMI), reaches up to approximately 90% target success on Qwen3-VL-8B-Instruct, and a cache-swap ablation localizes the influence to the KV cache. The attacks also survive compaction that retains the KV cache of a model-generated summary.","solution":"N/A -- no mitigation discussed in source.","labels":["security","research"],"sourceUrl":"https://arxiv.org/abs/2610.09027v1","publishedAt":"2026-10-06T19:25:08.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"info","attackType":["prompt_injection","jailbreak"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Qwen3-VL-8B-Instruct"],"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":"2026-10-06T19:25:08.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"advanced","impactType":["integrity","safety"],"aiComponentTargeted":"model","llmSpecific":true,"classifierConfidence":0.93,"researchCategory":"preprint","atlasIds":null}}
