description

SpreadProcessing versions earlier than 2026.3.1006 are affected when they import a malformed XLS document. An attacker who can cause such a file to be processed may consume a CPU thread indefinitely and disrupt service.

mitigation

Upgrade Telerik Document Processing SpreadProcessing to version 2026.3.1006 or later. Until upgraded, restrict or isolate processing of untrusted XLS files.

fixed in 2026.3.1006
