Addresses antivirus software flagging a DEP exploit warning when signing into Foxit eSign from within Foxit PDF Editor.

Answer

Support for Foxit PDF Editor v11 and v12 has been discontinued as of August13, 2025. Upgrade to v14 to continue receiving support.

 

An issue about DEP exploit has come to our attention recently.

Summary of the Issue: Foxit PDF Editor 11.2 users ​that have Sophos (or potentially other anti-virus software) installed and ​sign into Foxit eSign within the application could receive a DEP ​(data execution prevention) exploit message from the anti-virus software after they enter their ​Foxit credentials. ​It's important to note: This was reported internally and we are not aware of any reports from external users.

Here are the screenshots of the issue:

 

Impact: This issue appears to only impact non-enterprise users ​of Foxit eSign or possibly new Foxit PDF Editor subscription users that log in through the Foxit eSign workflow.

 

Resolution: A new Foxit eSign plugin has been created to fix this issue. The plug-in can be located here or installed via Help > About Foxit PDF Editor > Check for Update within the application.
