AI Analysis
Technical Summary
CVE-2026-47341 is an authentication bypass vulnerability in Apache APISIX affecting versions from 3.11.0 through 3.16.0. The issue arises from certain configurations in the hmac-auth plugin that enable an attacker to perform a capture-replay attack, reusing a token indefinitely and bypassing its expiry. This allows unauthorized access despite token expiration mechanisms. The Apache Software Foundation has addressed this vulnerability in version 3.17.0.
Potential Impact
An attacker can bypass authentication expiry controls by replaying captured tokens, effectively gaining unauthorized access to the system indefinitely under affected configurations. This compromises the authentication mechanism's integrity and could lead to unauthorized actions within Apache APISIX deployments using vulnerable versions.
Mitigation Recommendations
Users should upgrade Apache APISIX to version 3.17.0 or later, where this vulnerability is fixed. No alternative mitigations or temporary fixes are indicated. Patch status is confirmed by the vendor advisory recommending the upgrade.
