Prior to 9.6.0-alpha.5 and 8.6.31, a 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. Only Postgres deployments are affected. This vulnerability is fixed in 9.6.0-alpha.5 and 8.6.31.","published":"2026-03-11T18:01:16.804Z","modified":"2026-08-07T11:50:09.311727851Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"parse-server","fixedVersion":"9.6.0-alpha.5"},{"ecosystem":"npm","name":"parse-server","fixedVersion":"8.6.31"}],"fix":null,"references":[{"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"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31871.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:09.311727851Z"}}
