{"apiVersion":"1.0","identifier":"CVE-2026-53572","description":"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.","publishedAt":"2026-08-21T21:16:59","lastModifiedAt":"2026-08-25T18:17:55","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-53572","cvssScore":5.9,"cvssVector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N","epssProbability":0.00319,"riskScore":0.61,"affectedProduct":"KEDA","affectedVersions":"<2.20.0","vulnerabilityType":"Library","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-53572","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-53572","en":"https://www.redsauce.net/en/cves/CVE-2026-53572","fr":"https://www.redsauce.net/fr/cves/CVE-2026-53572","pt":"https://www.redsauce.net/pt/cves/CVE-2026-53572","de":"https://www.redsauce.net/de/cves/CVE-2026-53572","sk":"https://www.redsauce.net/sk/cves/CVE-2026-53572","el":"https://www.redsauce.net/el/cves/CVE-2026-53572"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-53572"}}
