path-to-regexp vulnerable to Denial of Service via sequential optional groups
CVSS 3.1
7.5بالا
شرح رسمی (انگلیسی)
Impact: A bad regular expression is generated any time you have multiple sequential optional groups (curly brace syntax), such as `{a}{b}{c}:z`. The generated regex grows exponentially with the number of groups, causing denial of service. Patches: Fixed in version 8.4.0. Workarounds: Limit the number of sequential optional groups in route patterns. Avoid passing user-controlled input as route patterns.
