{"id":"GHSA-gqpp-xgvh-9h7h","summary":"Parse Server vulnerable to SQL Injection via dot-notation sub-key name in `Increment` operation on PostgreSQL","details":"### Impact\n\nA SQL injection vulnerability exists in the PostgreSQL storage adapter when processing `Increment` operations on nested object fields using dot notation (e.g., `stats.counter`). The sub-key name is interpolated directly into SQL string literals without escaping. An attacker who can send write requests to the Parse Server REST API can inject arbitrary SQL via a crafted sub-key name containing single quotes, potentially executing commands or reading data from the database, bypassing CLPs and ACLs.\n\nOnly Postgres deployments are affected.\n\n### Patches\n\nThe fix escapes single quotes in the sub-key name before interpolating it into the SQL query, preventing breakout from SQL string literals.\n\n### Workarounds\n\nThere is no known workaround.\n\n### References\n\n- GitHub security advisory: https://github.com/parse-community/parse-server/security/advisories/GHSA-gqpp-xgvh-9h7h\n- Fix Parse Server 9: https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.5\n- Fix Parse Server 8: https://github.com/parse-community/parse-server/releases/tag/8.6.31","aliases":["BIT-parse-2026-31871","CVE-2026-31871"],"modified":"2026-03-13T13:11:07.210484Z","published":"2026-03-11T00:34:40Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-03-11T00:34:40Z","nvd_published_at":"2026-03-11T18:16:26Z","cwe_ids":["CWE-89"],"severity":"CRITICAL"},"references":[{"type":"WEB","url":"https://github.com/parse-community/parse-server/security/advisories/GHSA-gqpp-xgvh-9h7h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31871"},{"type":"PACKAGE","url":"https://github.com/parse-community/parse-server"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/8.6.31"},{"type":"WEB","url":"https://github.com/parse-community/parse-server/releases/tag/9.6.0-alpha.5"}],"affected":[{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"9.0.0-alpha.1"},{"fixed":"9.6.0-alpha.5"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-gqpp-xgvh-9h7h/GHSA-gqpp-xgvh-9h7h.json"}},{"package":{"name":"parse-server","ecosystem":"npm","purl":"pkg:npm/parse-server"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"8.6.31"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-gqpp-xgvh-9h7h/GHSA-gqpp-xgvh-9h7h.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
