Description

A vulnerability in Progress Telerik Document Processing Libraries prior to version 2026.3.1027 allows improper verification of cryptographic signatures and certificate validation in RadPdfProcessing. This flaw enables an unauthenticated attacker to craft a signed PDF document that causes the signature validation to incorrectly report forged content as unmodified and the signing certificate as valid.
