An unauthenticated remote attacker can send an oversized GET request to dispatcher.cgi to cause denial of service of the web management interface and potentially trigger memory corruption.","published":"2026-08-28T20:19:52.970","modified":"2026-08-28T20:19:52.970","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://www.planet.com.tw/en/support/security-advisory/10"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/planet-gs-4210-16p2s-memory-corruption-via-dispatcher-cgi-readhttpparam"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-28T20:19:52.970"}}
