How to Fix CVE-2026-40945

To remediate this vulnerability, upgrade all affected Github.com/oxia db/oxia dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

github.com/oxia-db/oxia fixed: 0.16.2 
Upgrade github.com/oxia-db/oxia to 0.16.2
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

inspect dependencies for github.com/oxia-db/oxia

How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-40945, inspect your project dependencies for Github.com/oxia db/oxia:

inspect dependencies for github.com/oxia-db/oxia

Analyze the terminal output to locate any version of Github.com/oxia db/oxia in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 0.16.2), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-532: Insertion of Sensitive Information into Log File, where the product writes sensitive information to a log file. In Github.com/oxia db/oxia, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary When OIDC authentication fails, the full bearer token is logged at DEBUG level in plaintext. If debug logging is enabled in production, JWT tokens are exposed in application logs and any connected log aggregation system. ### Impact An attacker with access to application logs (e.g., via a compromised log aggregation pipeline, shared logging infrastructure, or misconfigured log access controls) can extract valid JWT tokens and replay them to authenticate as legitimate users. All versions using OIDC authentication are affected. ### Details In `oxiad/common/rpc/auth/interceptor.go`, the `validateTokenWithContext()` function logs the complete token value via `slog.String("token", token)` when authentication fails. This includes the full JWT header, payload, and signature. ### Patches Fixed by redacting the token in log output — only the last 8 characters are preserved for correlation purposes. ### Workarounds Ensure DEBUG-level logging is never enabled in production environments.
