OpenSignLabs opensignserver - Missing Authorization

Published Aug 10, 2026 CVSS 3.1 · 7.5 High EPSS < 1% KEV · Not listed
Description
A missing authorization vulnerability in OpenSignLabs opensignserver through 2.37.0 allows an unauthenticated remote attacker to irreversibly decline any in-flight document and forge the decline attribution to an arbitrary user via the declinedoc Parse cloud function. The function writes IsDeclined, DeclineReason, and a caller-supplied DeclineBy pointer without verifying the caller's identity, enabling workflow termination and evidentiary record falsification against any accessible document.
