EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.8 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 1.8%, top 23% of all CVEs by exploit prediction. 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).

GeoTools is an open source Java library that provides tools for geospatial data. Starting in version 30.5 and prior to versions 33.6, 34.5, and 33.6, an SQL Injection Vulnerability is present when executing OGC Filters with PostGIS DataStore implementation: jsonArrayContains function; Requires PostGIS 12 or greater with a String or JSON field. For PostGIS 12 and greater jsonArrayContains(, , ) function writes `` into generated SQL without escaping. Patches are available in versions 33.6, 34.5, and 33.6. No known workaround is available. To limit scope of SQL Injection the PostGIS connection pool should be configured with limited rights.
