Prior to 2.5.0, geopy.Point and Point.from_string() can spend excessive CPU time due to inefficient regular-expression behavior when an application passes a long malformed coordinate string without the 256-character input limit used by the fix. Geocoder reverse methods also reach the vulnerable parsing path when called with string inputs. Repeated attacker-controlled requests can cause a denial of service, while the numeric Point constructor is unaffected. This issue is fixed in version 2.5.0.","state":0,"publishedAt":"2026-10-01T16:38:54.176+00:00","modifiedAt":"2026-10-01T17:50:39.404+00:00","affected":[{"ecosystem":"Vendor product","name":"geopy","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"geopy\",\n                    \"product\": \"geopy\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.5.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","score":4,"severity":"MEDIUM"}],"references":["https://github.com/geopy/geopy/security/advisories/GHSA-mhvh-fq92-pfmr","https://github.com/geopy/geopy/issues/608","https://github.com/geopy/geopy/pull/610","https://github.com/geopy/geopy/commit/5d09fa843f90ec80788b61552539c9fd3ae6c528","https://github.com/geopy/geopy/releases/tag/2.5.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77387","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77387","identifiers":["CVE-2026-77387"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
