The APIVersion rule uses new Function() to evaluate expression strings, enabling an attacker to supply a malicious expression within rule configuration or crafted flow metadata. This could compromise developer machines, CI runners, or editor environments. This issue is fixed in version 6.10.6."

  "details": "### Impact\nThe APIVersion rule uses `new Function()` to evaluate expression strings. A malicious crafted flow metadata file can cause arbitrary JavaScript execution during scanning. An attacker could execute arbitrary JavaScript during a scan by supplying a malicious expression within rule configuration or crafted flow metadata. This could compromise developer machines, CI runners, or editor environments.\n\n### Patches\nThe patch removes all uses of `new Function()` and replaces them with a safer parser. It now validates operators (`\u003e`, \u003e=`, `\u003c`, `\u003c=`, `==`) and performs numeric comparisons without evaluating untrusted JavaScript.\n\n**version:** core-v6.10.6,\n**version vsx:**: v2.4.4\n**version app:**: v3.1.0\n\n### Work around\n\n```\n// --- Handle APIVersion rule separately to avoid unsafe-eval in the core library ---\n      const apiVersionConfig = ruleConfig.rules.APIVersion;\n      if (apiVersionConfig) {\n        delete ruleConfig.rules.APIVersion;\n      }\n\n// Manually evaluate the APIVersion rule, if it was configured.\n      if (apiVersionConfig) {\n        const flowApiVer = this.currentFlow.apiVersion || this.currentFlow.xmlData?.apiVersion;\n        const apiVersionRuleDef = allRules.find(r =\u003e r.name === \"APIVersion\");\n\n        // Determine the required expression (e.g. \"\u003e=58\").\n        let requiredExpr;\n        if (apiVersionConfig.expression) {\n          requiredExpr = apiVersionConfig.expression;\n        } else if (apiVersionConfig.threshold != null) {\n          requiredExpr = `\u003e=${apiVersionConfig.threshold}`;\n        }\n\n        if (requiredExpr) {\n          const minVer = parseInt(requiredExpr.replace(/[^0-9]/g, \"\"), 10);\n          const operator = requiredExpr.replace(/[0-9]/g, \"\").trim();\n          const operators = {\n            \"\u003e=\": (a, b) =\u003e a \u003c b,\n            \"\u003c\": (a, b) =\u003e a \u003e= b,\n            \"\u003e\": (a, b) =\u003e a \u003c= b,\n            \"\u003c=\": (a, b) =\u003e a \u003e b,\n            \"==\": (a, b) =\u003e a !== b,\n            \"=\": (a, b) =\u003e a !== b\n          };\n          const violation = operators[operator] ? operators[operator](flowApiVer, minVer) : flowApiVer \u003c minVer;\n\n          if (violation) {\n            // Craft a result object that mimics the core scanner output so downstream logic remains unchanged.\n            const manualScanResult = [{\n              flow: parsedFlow,\n              ruleResults: [{\n                ruleName: \"APIVersion\",\n                ruleDefinition: {\n                  description: apiVersionRuleDef?.description || \"API Version check\",\n                  label: apiVersionRuleDef?.label || \"APIVersion\"\n                },\n                occurs: true,\n                severity: apiVersionConfig.severity,\n                details: [{\n                  name: String(flowApiVer),\n                  type: \"apiVersion\",\n                  expression: requiredExpr\n                }]\n              }]\n            }];\n            results.push(...this.processScanResults(manualScanResult));\n          }\n        }\n      }\n\n```",
