CVE-2026-77387: geopy: Regular Expression Denial of Service (ReDoS) in geopy.Point

geopy.Point and Point.from_string() may take excessive CPU time when parsing long, malformed coordinate strings due to inefficient regular-expression behavior. The numeric Point constructor is not affected.

Geocoders’ reverse methods called with string inputs exercise the vulnerable path.

Applications are affected when they pass attacker-controlled strings to these APIs without an appropriate length limit. Repeated requests may cause denial of service.
