{"id":"AZL-96989","summary":"CVE-2026-53572 affecting package keda 2.14.1-18","details":"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.","modified":"2026-09-19T05:33:49Z","published":"2026-08-21T21:16:59Z","upstream":["CVE-2026-53572"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53572"}],"affected":[{"package":{"name":"keda","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/keda"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.14.1-18"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-96989.json"}}],"schema_version":"1.9.0"}
