The vulnerability exists due to incorrect processing of documents that are embedded with specific triggers in the signing phase. A remote attacker can deceive users into signing the manipulated documents.

According to its version, the Foxit PDF Editor for Mac application (previously named Foxit PhantomPDF for Mac) installed on the remote macOS host is prior to 2025.2.1/14.0.1. It is, therefore affected by multiple vulnerabilities:

  - Address a potential issue where the application could be exposed to a Signature-Based Trust Bypass     vulnerability when handling certain documents that are embedded with specific triggers in the signing     phase, which attackers could exploit to deceive users into signing the manipulated documents. This occurs     as the application fails to explicitly prompt users after the self-modification action is triggered to     modify the document during the pre-signing phase. (CVE-2025-59803)

  - Addressed potential issues where the application could deliver incorrect signature verification     information when handling certain signed documents that contain JavaScripts, which attackers could exploit     to manipulate document content and deceive users into trusting the manipulated documents. This occurs as     the application fails to perform proper validation of cryptographic signatures after the visibility of     certain optional content groups is dynamically altered by JavaScripts or triggers during the post-signing     phase. (CVE-2025-59802)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

According to its version, the Foxit PDF Reader for Mac application (previously named Foxit Reader for Mac) installed on the remote macOS host is prior to 2025.2.1. It is, therefore affected by multiple vulnerabilities:
