git-urls 1.0.0 allows ReDOS (Regular Expression Denial of Service) in urls.go.

Weakness

The product uses a regular expression with an inefficient, possibly exponential worst-case computational complexity that consumes excessive CPU cycles.

Affected Software

Name Vendor Start Version End Version
Git-urls Git-urls_project 1.0.1 (including) 1.0.1 (including)

Extended Description

      Attackers can create crafted inputs that
      intentionally cause the regular expression to use
      excessive backtracking in a way that causes the CPU
      consumption to spike.
