CVE-2026-11400 and CVE-2026-11401
CVE-2026-11400 and CVE-2026-11401 are privilege escalation vulnerabilities in AWS Wrappers for Amazon Aurora PostgreSQL. A low privilege authenticated user can create a crafted function that executes with the permissions of other Amazon RDS users, including the rds_superuser role. The issue affects AWS Advanced JDBC Wrapper versions from 3. 0. 0 up to but not including 4. 0. 1, and AWS Advanced Go Wrapper release 2026-04-06. AWS has released fixed versions: JDBC Wrapper 4. 0. 1 and Go Wrapper 2026-05-26.
AI Analysis
Technical Summary
Amazon Aurora PostgreSQL's AWS Advanced JDBC and Go Wrappers contain vulnerabilities (CVE-2026-11400 and CVE-2026-11401) that allow a low privilege authenticated user to escalate privileges to the rds_superuser role by creating crafted functions executed with elevated permissions. The affected versions are AWS Advanced JDBC Wrapper >=3.0.0 and <4.0.1, and AWS Advanced Go Wrapper release 2026-04-06. AWS has addressed these issues in JDBC Wrapper 4.0.1 and Go Wrapper 2026-05-26. The vulnerability arises from improper permission handling in the wrappers, enabling unauthorized privilege escalation within Amazon RDS environments.
Potential Impact
The vulnerability allows privilege escalation to the rds_superuser role, which grants extensive administrative capabilities within Amazon Aurora PostgreSQL instances. This could enable an attacker with low privileges to perform unauthorized actions with elevated permissions, potentially compromising database integrity and confidentiality. There are no known exploits in the wild at this time.
Mitigation Recommendations
AWS has released official fixes in AWS Advanced JDBC Wrapper version 4.0.1 and AWS Advanced Go Wrapper release 2026-05-26. Users should upgrade to these versions or later to remediate the vulnerability. As a temporary workaround, removing the public schema from the search path can reduce exposure. Ensure any forked or derivative code is also updated to incorporate these fixes.
