CVE-2026-126793 · Severity: high · CVSS 8 · Published 2026-11-12

AWS Advanced Go Wrapper is a Go database driver that connects applications to Amazon Aurora PostgreSQL clusters. An authenticated database user with function creation privileges can exploit a flaw in the wrapper's dialect detection to escalate privileges to other database users, potentially including superuser-level access, when another user connects through the affected wrapper version.

## Quick answers

**Is CVE-2026-126793 exploited in the wild?** No. Junglewise Threat Intelligence has no report of CVE-2026-126793 being exploited in the wild.

**How severe is CVE-2026-126793?** High severity, with a CVSS score of 8, published 12 November 2026.

**Which products and versions are affected?** Amazon Advanced Go Wrapper 2.0.0 through 2.0.2.

**Is there a fix for CVE-2026-126793?** Yes: fixed in AWS Advanced Go Wrapper 2.0.3. Until then: Revoke CREATE privilege on the public schema from PUBLIC using 'REVOKE CREATE ON SCHEMA public FROM PUBLIC;' and grant CREATE on other schemas in the search_path only to trusted database users. Junglewise finds every place you run it, drafts the upgrade and applies it once you approve.

**How is CVE-2026-126793 attacked?** It is attacked over the network, in a software library.

**Am I affected by CVE-2026-126793?** Check whether you run Amazon Advanced Go Wrapper or Amazon AWS at an affected version. Junglewise does that check for you around the clock: connect your code, cloud and domains, and it matches new vulnerabilities like this one against what you actually run and tells you when one reaches you.

## How to fix

- Fixed in AWS Advanced Go Wrapper 2.0.3

Revoke CREATE privilege on the public schema from PUBLIC using 'REVOKE CREATE ON SCHEMA public FROM PUBLIC;' and grant CREATE on other schemas in the search_path only to trusted database users.

## Technical details

An untrusted search path vulnerability in Aurora PostgreSQL dialect detection allows a malicious function to be executed with the privileges of the connecting user. An authenticated attacker who can create functions in a schema on the search path of another database user can trigger privilege escalation when that target user connects to the Aurora cluster via the affected wrapper. The vulnerability is a search path injection issue tied to the wrapper's dialect detection mechanism.

## Affected products

- Amazon Advanced Go Wrapper 2.0.0 through 2.0.2
