A flaw in the getPath utility function could allow path confusion and potential bypass of proxy-level ACLs (e.g. Nginx location blocks).
The original implementation relied on fixed character offsets when parsing request URLs. Under certain malformed absolute-form Request-URIs, this could lead to incorrect path extraction.
Most standards-compliant runtimes and reverse proxies reject such malformed requests with a 400 Bad Request, so the impact depends on the application and environment.
If proxy ACLs are used to protect sensitive endpoints such as /admin, this flaw could have allowed unauthorized access. The confidentiality impact depends on what data is exposed: if sensitive administrative data is exposed, the impact may be High (CVSS 7.5); otherwise it may be Medium (CVSS 5.3).
The implementation has been updated to correctly locate the first slash after "://", preventing such path confusion.
