CVE-2025-24671

Deserialization of Untrusted Data vulnerability in Pdfcrowd Save as PDF plugin by Pdfcrowd allows Object Injection. This issue affects Save as PDF plugin by Pdfcrowd: from n/a through 4.4.0.

Weakness

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

Potential Mitigations

• Make fields transient to protect them from deserialization.
• An attempt to serialize and then deserialize a class containing transient fields will result in NULLs where the transient data should be. This is an excellent way to prevent time, environment-based, or sensitive variables from being carried over and used improperly.
