{"id":"CVE-2022-35942","aliases":["GHSA-j259-6c58-9m58"],"url":"https://o3.security/vulnerability/CVE-2022-35942","summary":"loopback-connector-postgresql Vulnerable to Improper Sanitization of `contains` Filter","details":"Improper input validation on the `contains` LoopBack filter may allow for arbitrary SQL injection. When the extended filter property `contains` is permitted to be interpreted by the Postgres connector, it is possible to inject arbitrary SQL which may affect the confidentiality and integrity of data stored on the connected database. A patch was released in version 5.5.1. This affects users who does any of the following: - Connect to the database via the DataSource with `allowExtendedProperties: true` setting OR - Uses the connector's CRUD methods directly OR - Uses the connector's other methods to interpret the LoopBack filter. Users who are unable to upgrade should do the following if applicable: - Remove `allowExtendedProperties: true` DataSource setting - Add `allowExtendedProperties: false` DataSource setting - When passing directly to the connector functions, manually sanitize the user input for the `contains` LoopBack filter beforehand.","published":"2022-08-12T22:25:09Z","modified":"2026-07-15T01:49:13.233795882Z","cvss":{"score":9.3,"severity":"CRITICAL","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"loopback-connector-postgresql","fixedVersion":"5.5.1"}],"fix":{"url":"https://github.com/loopbackio/loopback-connector-postgresql/commit/d57406c6737692a3a106b58a35406290cddb23e5","label":"loopbackio/loopback-connector-postgresql@d57406c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/35xxx/CVE-2022-35942.json"},{"type":"ADVISORY","url":"https://github.com/loopbackio/loopback-connector-postgresql/security/advisories/GHSA-j259-6c58-9m58"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-35942"},{"type":"FIX","url":"https://github.com/loopbackio/loopback-connector-postgresql/commit/d57406c6737692a3a106b58a35406290cddb23e5"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:13.233795882Z"}}
