This critical-severity CVE scores 9.3 under NVD CVSS v3. EPSS exploit probability: 0.6% (47th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

A fix is available — apply it.

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.
