{"id":"CVE-2026-77387","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-77387","generatedAt":"2026-10-28T04:34:01.894Z","title":"Geocoder reverse methods also reach the vulnerable parsing path when called with string inputs.","description":"geopy is a geocoding library for Python. 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.","published":"2026-10-01T17:17:32.000Z","lastModified":"2026-10-02T18:04:11.000Z","status":"Awaiting Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"cwe":["CWE-1333"],"affected":[],"epss":{"score":0.00202,"percentile":0.10013,"date":"2026-10-27","history":[{"date":"2026-10-02","score":0.00201,"percentile":0.08993}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.20%).
