This creates a denial of service attack (making a service unavailable to users) that lasts until the user manually fixes it.","solution":"Users can recover by opening the memory tool, locating and removing suspicious memories created by the attacker. Additionally, users can entirely disable the memory feature to prevent this type of attack.","labels":["security","safety"],"sourceUrl":"https://embracethered.com/blog/posts/2024/chatgpt-persistent-denial-of-service/","publishedAt":"2024-07-08T21:30:18.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"medium","attackType":["prompt_injection","denial_of_service"],"issueType":"news","affectedPackages":null,"affectedVendors":["OpenAI"],"affectedVendorsRaw":["ChatGPT","OpenAI"],"classifierModel":"claude-haiku-4-5-20251001","classifierPromptVersion":"v3","cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":null,"epssScore":null,"patchAvailable":null,"disclosureDate":null,"capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["availability","integrity"],"aiComponentTargeted":"api","llmSpecific":true,"classifierConfidence":0.92,"researchCategory":null,"atlasIds":null}}
