CVE-2024-4412

Expression Language Injection via User Input in Multiple WSO2 Products Permits Arbitrary Operations

Published Oct 19, 2026 CVSS 3.1 · 2.7 Low EPSS < 1% KEV · Not listed

Description

The software accepts user-supplied data without sufficient validation, allowing for the injection of malicious Expression Language (EL) code. This can lead to the execution of arbitrary operations within the affected deployment.

Exploitation of this vulnerability requires administrator privileges. The impact is minimal as EL usage is restricted to certain read operations.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
