An issue was discovered in Foxit PDF and Editor for Windows and macOS before 13.2 and 2025 before 2025.2. A crafted PDF can use JavaScript to alter annotation content and subsequently clear the files modification status via JavaScript interfaces. This circumvents digital signature verification by hiding document modifications, allowing an attacker to mislead users about the documents integrity and compromise the trustworthiness of signed PDFs.
Weakness
The product does not verify, or incorrectly verifies, the cryptographic signature for data.
