  • Source referencedocs.telerik.com
Upstream source description

In Progress® Telerik® Document Processing Libraries prior to version 2026.3.1027, improper verification of cryptographic signatures and improper certificate validation in RadPdfProcessing digital signature validation allow an unauthenticated attacker to cause signature validation to report forged content as unmodified and its signing certificate as valid via a crafted signed PDF document.
