Technical details
The vulnerability is a reliance on untrusted inputs in a security decision (CWE-345) within Apache APISIX's attach-consumer-label plugin. The plugin fails to sanitize client-supplied consumer-label headers, allowing an attacker to inject crafted values that bypass authorization logic or escalate privileges. The vulnerability is exploitable over the network without authentication and affects APISIX versions 3.11.0 through 3.17.0. An attacker can perform authorization bypass or privilege escalation by sending specially crafted header values. The issue is patched in version 3.18.0.
