CVE-2025-10911

A use-after-free vulnerability was found in libxslt while parsing xsl nodes that may lead to the dereference of expired pointers and application crash.

What this means for your business

  • An attacker can use it only with access to the machine itself, without a login, but only after tricking someone into an action such as opening a file or a link.

What to do

  1. 1Ask your IT team or provider whether any of your systems use the affected product.
  2. 2If you do, follow the vendor's guidance. No patch reference has been published yet.
