Tool JSON parsed from the rendered body of a {% completion %} block can name any importable attribute, such as os.system, and when the LLM emits a matching tool_calls entry the callable runs with arguments from the model output, giving arbitrary code execution in the banks-hosting process. The report states this is distinct from GHSA-gphh-9q3h-jgpp / CVE-2026-44209, whose 2.4.2 fix (switching env.py to SandboxedEnvironment) does not cover this path.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-64vx-6h2c-rjh7","publishedAt":"2026-11-05T17:51:02.000Z","cveId":"CVE-2026-61536","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["banks@<= 2.4.2 (fixed: 2.4.3)"],"affectedPackageNames":["banks"],"affectedPackageRefs":["pypi:banks"],"affectedVendors":[],"affectedVendorsRaw":["banks"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00377,"epssCheckedAt":"2026-11-05T18:10:02.073Z","kevDateAdded":null,"advisoryAliases":["GHSA-64vx-6h2c-rjh7"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-11-05T17:51:02.000Z","fixReleasedAt":"2026-06-18T14:41:34.999Z","daysToFix":-140,"fixCheckedAt":"2026-11-05T18:10:31.970Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"plugin","llmSpecific":true,"classifierConfidence":0.95,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"banks","fixedVersion":"2.4.3","matchedVersion":"2.4.3","fixReleasedAt":"2026-06-18T14:41:34.999Z","daysToFix":-140,"match":"ecosystem","source":"tracked","status":"found","checkedAt":"2026-11-05T18:10:31.683Z"}]}}
