CVE-2025-59802

⚡ A crafty JavaScript attack can change what you see in signed PDFs, all while keeping the signature intact! This is like a magician who swaps out the content of a signed contract after the ink has dried—impression is one thing, but the details can change under the spotlight! An attacker can manipulate the visibility of the Optional Content Groups (OCG) in a signed PDF, leading to a deceitful mismatch between what the signer intended and what the verifier sees. This could severely undermine trust in digital signatures, potentially allowing fraudulent documents to be passed off as legitimate.
