giturlparse (aka git-url-parse) through 1.2.2, as used in Semgrep 1.5.2 through 1.24.1, is vulnerable to ReDoS (Regular Expression Denial of Service) if parsing untrusted URLs. This might be relevant if Semgrep is analyzing an untrusted package (for example, to check whether it accesses any Git repository at an http:// URL), and that packages author placed a ReDoS attack payload in a URL used by the package.
Weakness
The product uses a regular expression with a worst-case computational complexity that is inefficient and possibly exponential.
