{"id":"GHSA-p2w6-rmh7-w8q3","summary":"Parse Server has SQL Injection through aggregate and distinct field names in PostgreSQL adapter","details":"### Impact\n\nAn attacker with master key access can execute arbitrary SQL statements on the PostgreSQL database by injecting SQL metacharacters into field name parameters of the aggregate `$group` pipeline stage or the `distinct` operation. This allows privilege escalation from Parse Server application-level administrator to PostgreSQL database-level access.\n\nOnly Parse Server deployments using PostgreSQL are affected. MongoDB deployments are not affected.\n\n### Patches\n\nField names in the aggregate `$group._id` object values and `distinct` dot-notation parameters are now validated to only contain alphanumeric characters and underscores, preventing SQL injection via the `:raw` interpolation used in the PostgreSQL storage adapter.\n\n### Workarounds\n\nNo workaround. Upgrade to a patched version.","aliases":["BIT-parse-2026-33539","CVE-2026-33539"],"modified":"2026-03-27T22:03:50.528822Z","published":"2026-03-24T19:12:06Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-24T19:12:06Z","nvd_published_at":"2026-03-24T19:16:54Z","cwe_ids":["CWE-89"],"severity":"HIGH"},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-p2w6-rmh7-w8q3"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33539"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10272"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/pull/10273"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/03249f9bf5b8783c8b848f84dab791ff0b761b8c"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/commit/bdddab5f8b61a40cb8fc62dd895887bdd2f3838e"},{"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.53"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-p2w6-rmh7-w8q3/GHSA-p2w6-rmh7-w8q3.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.59"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-p2w6-rmh7-w8q3/GHSA-p2w6-rmh7-w8q3.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
