{"id":"CVE-2024-10550","summary":"Denial of Service by ReDOS in h2oai/h2o-3","details":"A vulnerability in the `/3/ParseSetup` endpoint of h2oai/h2o-3 version 3.46.0.1 allows for a denial of service (DoS) attack. The endpoint applies a user-specified regular expression to a user-controllable string. This can be exploited by an attacker to cause inefficient regular expression complexity, leading to the exhaustion of server resources and making the server unresponsive.","aliases":["GHSA-7qq7-pvm9-x8rf","PYSEC-2026-1440"],"modified":"2026-08-12T03:51:20.171691526Z","published":"2025-03-20T10:10:11.240Z","database_specific":{"cna_assigner":"@huntr_ai","cwe_ids":["CWE-1333"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/10xxx/CVE-2024-10550.json"},"references":[{"type":"WEB","url":"https://huntr.com/bounties/ef3f4d89-3b8b-4618-b134-cb93c1664ec6"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/10xxx/CVE-2024-10550.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-10550"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/h2oai/h2o-3","events":[{"introduced":"a35cd8a449055c283049e880e77b52bbd7e976e5"},{"last_affected":"a35cd8a449055c283049e880e77b52bbd7e976e5"}],"database_specific":{"extracted_events":[{"introduced":"3.46.0.1"},{"last_affected":"3.46.0.1"}],"source":"CPE_STRING","cpe":"cpe:2.3:a:h2o:h2o:3.46.0.1:*:*:*:*:*:*:*"}}],"versions":["3.46.0.1","jenkins-rel-3.46.0-1","jenkins-3.46.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-10550.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
