CVE-2026-117468 · Severity: medium · CVSS 6.5 · Published 2026-10-27

Psono Server is a password manager and secrets management platform. A vulnerability in versions 5.3.5 through 7.2.3 allows an authenticated attacker with a restricted API key to claim a device code and obtain an unrestricted read-write session lasting up to 365 days, bypassing the original token's scope and lifetime restrictions. This could enable unauthorized access to all secrets managed by the application.

## Technical details

A permission class in Psono Server failed to enforce token write scope validation when processing device code claims. An authenticated attacker with a restricted API key-derived session could exploit this by claiming an attacker-controlled device code to obtain a full read-write session with extended validity, circumventing the original token's scope and lifetime constraints. Two-factor authentication and plaintext secret disclosure were not bypassed.
