A researcher, with help from an AI agent, found a proof-of-concept vulnerability in about 10 minutes that could alter what the reviewer sees, including previous actions and the viewer's Download button. The underlying trajectory remains in METR's database, and METR reports no observed agent exploitation.","solution":"N/A -- no mitigation discussed in source.","labels":["security","safety"],"sourceUrl":"https://metr.org/blog/2026-10-06-ai-systems-could-cover-up-misbehavior/","publishedAt":"2026-10-06T07:00:00.000Z","cveId":null,"cweIds":null,"cvssScore":null,"cvssSeverity":null,"severity":"low","attackType":["other"],"issueType":"research","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":[],"affectedVendorsRaw":["Inspect"],"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":"2026-10-06T07:00:00.000Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["integrity","confidentiality"],"aiComponentTargeted":"framework","llmSpecific":false,"classifierConfidence":0.8,"researchCategory":"industry","atlasIds":null}}
