{"id":"CVE-2026-33539","summary":"Parse Server: SQL injection via aggregate and distinct field names in PostgreSQL adapter","details":"Parse Server is an open source backend that can be deployed to any infrastructure that can run Node.js. Prior to versions 8.6.59 and 9.6.0-alpha.53, an 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. Only Parse Server deployments using PostgreSQL are affected. MongoDB deployments are not affected. This issue has been patched in versions 8.6.59 and 9.6.0-alpha.53.","aliases":["BIT-parse-2026-33539","GHSA-p2w6-rmh7-w8q3"],"modified":"2026-08-12T03:51:33.783076503Z","published":"2026-03-24T18:26:56.046Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33539.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-89"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33539.json"},{"type":"ADVISORY","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":"FIX","url":"https://github.com/parse-community/parse-server/commit/03249f9bf5b8783c8b848f84dab791ff0b761b8c"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/commit/bdddab5f8b61a40cb8fc62dd895887bdd2f3838e"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10272"},{"type":"FIX","url":"https://github.com/parse-community/parse-server/pull/10273"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/parse-community/parse-server","events":[{"introduced":"0"},{"fixed":"eeabc97878a8112c5a32be1609e72ef562dde9f2"},{"introduced":"532a461d30a6ed4457839f2caf5f30d5abf51a55"},{"fixed":"cb062a6bca0827265804fd6ad60a55f1a360c15e"},{"fixed":"03249f9bf5b8783c8b848f84dab791ff0b761b8c"},{"fixed":"bdddab5f8b61a40cb8fc62dd895887bdd2f3838e"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"8.6.59"},{"introduced":"9.0.0"},{"fixed":"9.6.0"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:parseplatform:parse-server:*:*:*:*:*:node.js:*:*"}}],"versions":["9.5.1","9.6.0-alpha.52","8.6.58","8.6.57","9.6.0-alpha.51","9.6.0-alpha.50","9.6.0-alpha.49","9.6.0-alpha.48","8.6.56","9.6.0-alpha.47","9.6.0-alpha.46","9.6.0-alpha.45","9.6.0-alpha.44","8.6.55","8.6.54","9.6.0-alpha.43","9.6.0-alpha.42","8.6.53","9.6.0-alpha.41","8.6.52","9.6.0-alpha.40","8.6.51","9.6.0-alpha.39","8.6.50","9.6.0-alpha.38","9.6.0-alpha.37","9.6.0-alpha.36","9.6.0-alpha.35","9.6.0-alpha.34","8.6.49","9.6.0-alpha.33","9.6.0-alpha.32","9.6.0-alpha.31","9.6.0-alpha.30","9.6.0-alpha.29","9.6.0-alpha.28","8.6.48","8.6.47","9.6.0-alpha.27","9.6.0-alpha.26","9.6.0-alpha.25","9.6.0-alpha.24","9.6.0-alpha.23","8.6.46","9.6.0-alpha.22","8.6.45","9.6.0-alpha.21","9.6.0-alpha.20","8.6.44","8.6.43","9.6.0-alpha.19","9.6.0-alpha.18","8.6.42","9.6.0-alpha.17","8.6.41","9.6.0-alpha.16","9.6.0-alpha.15","8.6.40","9.6.0-alpha.14","8.6.39","9.6.0-alpha.13","9.6.0-alpha.12","8.6.38","9.6.0-alpha.11","8.6.37","9.6.0-alpha.10","8.6.36","9.6.0-alpha.9","8.6.35","8.6.34","9.6.0-alpha.8","8.6.33","9.6.0-alpha.7","8.6.32","9.6.0-alpha.6","8.6.31","9.6.0-alpha.5","8.6.30","9.6.0-alpha.4","9.6.0-alpha.3","8.6.29","8.6.28","9.6.0-alpha.2","8.6.27","9.6.0-alpha.1","9.5.2-alpha.14","8.6.26","9.5.2-alpha.13","9.5.2-alpha.12","8.6.25","8.6.24","9.5.2-alpha.11","8.6.23","9.5.2-alpha.10","9.5.2-alpha.9","8.6.22","8.6.21","9.5.2-alpha.8","8.6.20","9.5.2-alpha.7","8.6.19","9.5.2-alpha.6","8.6.18","9.5.2-alpha.5","8.6.17","9.5.2-alpha.4","8.6.16","9.5.2-alpha.3","8.6.15","9.5.2-alpha.2","9.5.2-alpha.1","8.6.14","8.6.13","9.5.0","8.6.12","8.6.11","9.4.1","8.6.10","8.6.9","8.6.8","8.6.7","8.6.6","8.6.5","8.6.4","9.4.0","8.6.3","9.3.1","9.3.0","8.6.2","9.2.0","9.1.1","9.1.0","8.6.1","9.0.0","8.6.0","8.5.0","8.4.0","8.3.0","8.2.5","8.2.4","8.2.3","8.2.2","8.2.1","8.2.0","8.1.0","8.0.2","8.0.1","8.0.0","7.4.0","7.3.0","7.2.0","7.1.0","7.0.0","6.4.0","6.3.1","6.3.0","6.2.2","6.2.1","6.2.0","6.1.0","6.0.0","5.4.0","5.3.3","5.3.2","5.3.1","5.3.0","5.2.8","5.2.7","5.2.6","5.2.5","5.2.4","5.2.3","5.2.2","5.2.1","5.2.0","5.1.1","5.1.0","5.0.0","5.0.0-alpha.1","4.5.0","4.4.0","4.3.0","4.2.0","4.1.0","4.0.2","4.0.1","4.0.0","3.10.0","3.9.0","3.8.0","3.7.2","3.7.1","3.7.0","3.6.0","3.5.0","3.4.0","3.4.1","3.3.0","3.2.3","3.2.2","3.2.1","3.2.0","3.1.3","3.1.2","3.1.1","3.1.0","3.0.0","2.8.2","2.8.0","2.7.4","2.7.3","2.7.2","2.7.1","2.7.0","2.6.5","2.6.4","2.6.3","2.6.2","2.6.1","2.6.0","2.5.3","2.5.2","2.5.1","2.5.0","2.4.2","2.4.1","2.4.0","2.3.8","2.3.7","2.3.6","2.3.5","2.3.4","2.3.3","2.3.2","2.3.1","2.2.25","2.2.25-beta.1","2.2.24","2.2.23","2.2.22","2.2.21","2.2.20","2.2.19","2.2.18","2.2.17","2.2.16","2.2.15","2.2.14","2.2.13","2.2.12","2.2.11","2.2.10","2.2.9","2.2.8","2.2.7","2.2.6","2.2.5","2.2.4","2.2.3","2.2.2","2.2.1","2.2.0","2.1.6","2.1.5","2.1.4","2.1.3","2.1.2","2.1.1","2.1.0","2.0.8","2.0.7","2.0.3","2.0.6","2.0.5","2.0.4","2.0.2","2.0.1","2.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33539.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"}]}
