Does this matter?
Lower severity and a low EPSS score (0.68%). Track it; it rarely justifies an emergency change on its own.
Description
Reliance on Untrusted Inputs in a Security Decision vulnerability in Apache APISIX. This vulnerability allows an attacker to escalate privilege or perform an authorization bypass by sending certain values that the attach-consumer-label plugin does not sanitise correctly. This issue affects Apache APISIX: from 3.11.0 through 3.17.0. Users are recommended to upgrade to version 3.18.0, which fixes the issue.
