This critical-severity CVE scores 9.8 under NVD CVSS v3. EPSS exploit probability: 0.5%, top 59% 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).

Alerta is a monitoring tool. Prior to version 9.1.0, the Query string search API (q=) was vulnerable to SQL injection via the Postgres query parser, which built WHERE clauses by interpolating user-supplied search terms directly into SQL strings via f-strings. This issue has been patched in version 9.1.0.
