{"id":"CVE-2026-77387","summary":"geopy: Regular Expression Denial of Service (ReDoS) in geopy.Point","details":"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.","aliases":["GHSA-mhvh-fq92-pfmr"],"modified":"2026-10-02T03:47:36.967917675Z","published":"2026-10-01T16:38:54.176Z","related":["openSUSE-SU-2026:11724-1"],"database_specific":{"cwe_ids":["CWE-1333"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77387.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/77xxx/CVE-2026-77387.json"},{"type":"FIX","url":"https://github.com/geopy/geopy/commit/5d09fa843f90ec80788b61552539c9fd3ae6c528"},{"type":"REPORT","url":"https://github.com/geopy/geopy/issues/608"},{"type":"FIX","url":"https://github.com/geopy/geopy/pull/610"},{"type":"WEB","url":"https://github.com/geopy/geopy/releases/tag/2.5.0"},{"type":"ADVISORY","url":"https://github.com/geopy/geopy/security/advisories/GHSA-mhvh-fq92-pfmr"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-77387"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/geopy/geopy","events":[{"introduced":"0"},{"fixed":"402cbba8b093e5e3f89c81b902f576d65608a123"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.5.0"}],"source":"AFFECTED_FIELD"}}],"versions":["2.4.1","2.4.0","2.3.0","2.2.0","2.1.0","2.0.0","2.0.0rc1","1.22.0","1.21.0","1.20.0","1.19.0","1.18.1","1.18.0","1.17.0","1.16.0","1.15.0","1.14.0","1.13.0","1.12.0","1.11.0","1.10.0","1.9.1","1.9.0","1.8.1","1.8.0","1.7.1","1.7.0","1.6.1","1.6.0","1.5.0","1.4.0","1.3.0","1.2.0","1.1.5","1.1.3","1.1.2","1.1.1","1.1.0","1.0.1","1.0.0","0.99","0.98.3","0.98.2","0.98.1","0.98","0.97.1","release-0.97","0.97","release-0.96","0.96","release-0.95.1","0.95.1","release-0.95","0.95","release-0.94.2","0.94.2","release-0.94","0.94","release-0.93","0.93"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-77387.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"}]}
