KEDA is a Kubernetes-based Event Driven Autoscaling component. Prior to 2.20.0, pkg/scalers/postgresql_scaler.go constructs libpq-style connection strings from tenant-controlled host, port, userName, dbName, sslmode, and password values, while escapePostgreConnectionParameter() only quotes values containing a literal space. Tabs, newlines, carriage returns, form feeds, vertical tabs, quotes, and backslashes can therefore create additional key-value tokens when pgx parses the string. An attacker able to create or modify a TriggerAuthentication or ScaledObject can inject host or sslmode parameters, redirect the database connection to an attacker-controlled server, expose credentials, or disable intended TLS protection. This issue is fixed in version 2.20.0.
CVE-2026-53572
This medium-severity CVE scores 5.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 76% 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).
- Lower severity and no public exploit yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
