CVE-2026-108648 jeecgboot CVE debrief

Who should care

Defenders managing JeecgBoot instances, especially those with low-privileged user access, should assess exposure and prioritize remediation. This includes verifying JeecgBoot versions, restricting access to the affected endpoint, and monitoring for suspicious activity. Security teams should review compensating controls for exposed systems and plan vendor-supported updates through normal change control.

Why it matters

CVE-2026-108648 is a high-severity vulnerability in JeecgBoot that allows low-privileged users to access sensitive database information. Defenders should prioritize verification and remediation, especially those managing JeecgBoot instances with low-privileged user access.

• Potential unauthorized access to database credentials
• Possible lateral movement within the network
• Required verification of JeecgBoot version and updates
• Potential data breaches due to exposed database information

Technical summary

The vulnerability exists in the GET /sys/api/getDynamicDbSourceByCode endpoint of SystemApiController in JeecgBoot through 3.9.5. The endpoint lacks Shiro permission or role annotations, allowing any authenticated low-privileged user to supply datasource codes in the dbSourceCode parameter to retrieve JDBC URLs, usernames, and decrypted cleartext database passwords. This could lead to potential unauthorized access to database credentials, possible lateral movement within the network, and potential data breaches due to exposed database information.

Defensive priority

Defenders should prioritize verifying and remediating this vulnerability, especially those managing JeecgBoot instances.

Recommended defensive actions

• Verify JeecgBoot version and check for updates
• Restrict access to the affected endpoint
• Monitor for suspicious activity
• Implement compensating controls for exposed systems
• Review asset inventory for affected deployments
• Track exceptions and retest remediated assets
• Plan vendor-supported updates through normal change control
