{"id":"GHSA-9fjp-q3c4-6w3j","summary":"Parse Server has a query condition depth bypass via pre-validation transform pipeline","details":"### Impact\n\nAn attacker can send an unauthenticated HTTP request with a deeply nested query containing logical operators to permanently hang the Parse Server process. The server becomes completely unresponsive and must be manually restarted. This is a bypass of the fix for CVE-2026-32944.\n\n### Patches\n\nThe query condition nesting depth is now validated before the query enters the transformation pipeline, preventing deeply nested structures from being recursively processed before the existing depth guard can fire.\n\n### Workarounds\n\nNone.","aliases":["BIT-parse-2026-33498","CVE-2026-33498"],"modified":"2026-03-30T14:04:50.929318Z","published":"2026-03-20T20:56:22Z","database_specific":{"nvd_published_at":"2026-03-24T19:16:54Z","cwe_ids":["CWE-674"],"severity":"HIGH","github_reviewed":true,"github_reviewed_at":"2026-03-20T20:56:22Z"},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-9fjp-q3c4-6w3j"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33498"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10257"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10258"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/2581b5426047ce9cbcd3d9c0e8379e9c30e23ab5"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/85994eff9e7b34cac7e1a2f5791985022a1461d1"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0"},{"fixed":"9.6.0-alpha.44"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-9fjp-q3c4-6w3j/GHSA-9fjp-q3c4-6w3j.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.55"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-9fjp-q3c4-6w3j/GHSA-9fjp-q3c4-6w3j.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
