Technical Analysis
CVE-2026-75020 is an LDAP Injection vulnerability in Apache APISIX where improper neutralization of special elements in LDAP queries allows an authenticated user to impersonate another consumer entry outside the plugin's configured scope. This enables unauthorized authentication through APISIX by leveraging valid credentials for one LDAP entry to access another entry. The vulnerability affects Apache APISIX versions 2.11.0 through 3.17.0 and is fixed in version 3.18.0.
Potential Impact
An attacker with valid LDAP credentials for one directory entry can authenticate as a different consumer entry, bypassing access controls intended to restrict scope. This can lead to unauthorized access to resources or services mapped to the other consumer entry.
Mitigation Recommendations
Users should upgrade Apache APISIX to version 3.18.0 or later, where this LDAP Injection vulnerability has been fixed. No other mitigations are specified.
