Recurring patterns

The bug types that recur here, drawn from past fixes, not open vulnerabilities.

Command Injection: Execution of system commands via shell wrapping wrapper APIs can allow arbitrary code execution. The fix for CVE-2023-38889 avoided wrapping in shell invocations when retrieving user group details.

Signature Validation Bypass: Discrepancies in how URI paths are parsed and normalized compared to raw values during signature generation can lead to authentication bypasses on S3 proxy API calls.

Remote Code Execution: Historically vulnerable logging libraries (log4j 1.x) are susceptible to deserialization vulnerabilities like CVE-2019-17571. Upgrading dependencies and enforcing secure exclusions is vital.
