CVE-2026-47341
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAuthentication Bypass by Capture-replay vulnerability in Apache APISIX. Attacker can benefit from certain configurations in hmac-auth to re-use a token forever, bypassing expiry. This issue affects Apache APISIX: from 3.11.0 through 3.16.0. Users are recommended to upgrade to version 3.17.0, which fixes the issue.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe hmac-auth plugin in Apache APISIX versions 3.11.0-3.16.0 contains a capture-replay vulnerability that allows attackers to replay captured authentication tokens, bypassing expiry checks and enabling indefinite token reuse.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check Apache APISIX installation versionRun `apisix version` or inspect the version file in the APISIX installation directory to determine the exact version numberAffected if The installed version is 3.11.0, 3.11.1, 3.11.2, 3.12.0, 3.12.1, 3.13.0, 3.13.1, 3.14.0, 3.14.1, 3.15.0, 3.15.1, or 3.16.0 (any version >= 3.11.0 and < 3.17.0)
-
Verify hmac-auth plugin is enabledInspect the Apache APISIX configuration file (config.yaml) or check the enabled plugins via the APISIX admin API endpoint `/apisix/admin/plugins` to confirm hmac-auth is listed among enabled pluginsAffected if The hmac-auth plugin appears in the enabled plugins list in the APISIX configuration or admin API response
-
Check for hmac-auth consumer configurationQuery the APISIX admin API at `/apisix/admin/consumers` or inspect the consumer configuration file to identify consumers using the hmac-auth authentication methodAffected if There exists a consumer configured with the hmac-auth plugin (plugin name: `hmac-auth` in the consumer configuration)
-
Inspect hmac-auth replay protection settingsReview the hmac-auth plugin configuration for any nonce, timestamp validation, or replay protection parameters. Check if `validate_timestamp` or similar replay-prevention settings are properly configured and enforcedAffected if The hmac-auth plugin lacks proper timestamp/nonce validation or replay protection, allowing the same signed request to be reused
You are affected if Apache APISIX version is 3.11.0 or higher but below 3.17.0 AND the hmac-auth plugin is enabled and configured for consumer authentication

dbcve · scoped3.17.0
Upgrade Apache APISIX to version 3.17.0 or later to obtain the security patch for the hmac-auth plugin vulnerability.
3.17.0
- 1. Back up your current Apache APISIX configuration files (apisix.yaml, config.yaml) and any custom plugin configurations.
- 2. Review the Apache APISIX 3.17.0 release notes for any migration requirements or breaking changes specific to your configuration.
- 3. Stop the Apache APISIX service to prevent requests during upgrade.
- 4. Upgrade Apache APISIX to version 3.17.0 using your installation method (e.g., package manager, Docker image, or source compilation).
- 5. Restore your configuration files from the backup if needed.
- 6. Start the Apache APISIX service and verify it is running correctly.
- 7. Test the hmac-auth plugin functionality to confirm authentication is working as expected, including token expiry enforcement.
