AI Analysis
Technical Summary
CVE-2026-50892 is an access control vulnerability (CWE-284) in Nginx Proxy Manager v2.14.0 affecting the Let's Encrypt certificate download endpoint. Authenticated users can exploit this flaw to obtain TLS private keys via a specially crafted GET request. The vulnerability has a CVSS 3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N), reflecting network attack vector, low attack complexity, required privileges, no user interaction, unchanged scope, high confidentiality impact, and no integrity or availability impact. No patch or official remediation level is currently documented, and no known exploits in the wild have been reported.
Potential Impact
An authenticated attacker can access TLS private key material, compromising the confidentiality of encrypted communications. This exposure could lead to interception or impersonation attacks if the private keys are misused. The vulnerability does not impact integrity or availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict authenticated user access to the certificate download endpoint and monitor for suspicious activity related to certificate management. Avoid exposing the management interface to untrusted networks.
