CVE-2026-117472: Psono Server authorization bypass in bulk-secret-read with URL_PREFIX

CVE-2026-117472 · Severity: medium · CVSS 4.3 · Published 2026-10-27

Psono Server is a password and secret management platform. In deployments using URL_PREFIX configuration, an attacker with a write-only API key can bypass read restrictions and retrieve encrypted secret data and nonces through a path comparison flaw. This allows unauthorized data exposure despite intentional permission restrictions.

Vendors: Psono.

Technical details

The bulk-secret-read endpoint compares the request path against a hard-coded unprefixed path, causing authorization bypass when URL_PREFIX is configured. An authenticated remote attacker with write scope but no read scope on their API key can exploit this path mismatch to access the endpoint with write-level authorization instead of the required read-level authorization. The vulnerability only affects deployments explicitly using URL_PREFIX; default configurations are unaffected.
