CVE-2026-33722 describes a medium-severity authorization bypass in n8n versions prior to 2.6.4 and 1.123.23, allowing authenticated users to retrieve plaintext external secret values. This vulnerability, rated CVSS 5.3 (AV:N/AC:H/PR:L/C:H), requires an external secrets vault configuration and for the attacker to know or guess the secret name, making the attack complexity high. Successful exploitation results in high confidentiality impact by bypassing permission checks. There is no evidence of active exploitation, public exploit code, or significant community attention. Users should upgrade to patched versions 1.123.23 or 2.6.4, or later, to mitigate this risk.
