CVE-2026-53572— KEDA: PostgreSQL connection string parameter injection via incomplete whitespace escaping

Quick assessment

Affected
kedacore keda
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

KEDA是KEDA组织的一款事件驱动的自动缩放组件。 KEDA 2.20.0之前版本存在安全漏洞，该漏洞源于postgresql_scaler.go中构造libpq风格连接字符串时特殊字符转义不完整，可能导致攻击者通过创建或修改TriggerAuthentication或ScaledObject注入host或sslmode参数，重定向数据库连接到攻击者控制的服务器，暴露凭据或禁用TLS保护。

Vulnerability Title
KEDA: PostgreSQL connection string parameter injection via incomplete whitespace escaping
Source: CVE Program / CVE List V5
Vulnerability 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.
