CVE-2026-0637: Sensitive Information Disclosure via Event Publisher Logging in Multiple WSO2 Products
- Severity: medium (CVSS 4.4 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.2% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-08-06 · updated 2026-08-12
- Weakness: CWE-532
Description
When an Event Publisher output adapter is configured with irrelevant properties, the affected products log these properties. This logging occurs without sufficient validation or sanitization of the property values. A malicious actor with access to the 'wso2carbon' log files could retrieve sensitive information, such as user credentials or other confidential data, that was inadvertently logged due to misconfiguration, potentially leading to unauthorized access.
