How severe is GHSA-r236-5pc3-3qcp?

GHSA-r236-5pc3-3qcp has a CVSS score of 8/10, rated HIGH. Immediate patching is strongly recommended.

Which packages are affected by GHSA-r236-5pc3-3qcp?

GHSA-r236-5pc3-3qcp affects the following packages: github.com/aws/aws-advanced-go-wrapper/awssql/v2 (Go), github.com/aws/aws-advanced-go-wrapper/xray (Go), github.com/aws/aws-advanced-go-wrapper/aws-secrets-manager (Go), github.com/aws/aws-advanced-go-wrapper/custom-endpoint (Go), github.com/aws/aws-advanced-go-wrapper/federated-auth (Go), github.com/aws/aws-advanced-go-wrapper/iam (Go), github.com/aws/aws-advanced-go-wrapper/mysql-driver (Go), github.com/aws/aws-advanced-go-wrapper/okta (Go), and 3 more. Ecosystems affected: Go.

How do I fix GHSA-r236-5pc3-3qcp?

Update github.com/aws/aws-advanced-go-wrapper/awssql/v2 to 2.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-r236-5pc3-3qcp is resolved across your whole dependency graph.

How do I detect GHSA-r236-5pc3-3qcp in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/aws/aws-advanced-go-wrapper/awssql/v2, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-r236-5pc3-3qcp if there is no patch (or I can't update yet)?

Close the privilege gap rather than the entry point: audit which accounts, roles and service identities can reach the affected operation, drop the component to the least privilege it actually needs, and review file and directory permissions created by earlier installs — a default left in place is what makes this reachable.

Is GHSA-r236-5pc3-3qcp actively exploited in the wild?

No public exploit code has been indexed for GHSA-r236-5pc3-3qcp yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for GHSA-r236-5pc3-3qcp?

GHSA-r236-5pc3-3qcp has an EPSS (Exploit Prediction Scoring System) score of 0.3%, placing it in the 21th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

What type of vulnerability is GHSA-r236-5pc3-3qcp?

GHSA-r236-5pc3-3qcp is classified as CWE-426 (CWE-426). This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation.

When was GHSA-r236-5pc3-3qcp published, and has it been updated?

GHSA-r236-5pc3-3qcp was published on June 11, 2026 and was last updated on June 25, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
