In 3.7.0 and earlier, a POST request to /sources_to_targets containing an exclude_polygons ring formed by three collinear points can cause unbounded memory growth in the worker. The zero-area geometry, rather than the other request options, triggers processing in src/loki/polygon_search.cc until the process is terminated by the out-of-memory killer. A single unauthenticated request can therefore stop a public-facing worker. Other endpoints that accept exclude_polygons, including /route, were not verified as affected. No fixed version is available as of this review.","published":"2026-09-17T20:16:52.730","modified":"2026-09-17T20:16:52.730","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/valhalla/valhalla/security/advisories/GHSA-qpf6-xp29-pg6r"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-09-17T20:16:52.730"}}
