Local memory disclosure to standard users
Published Jul 14, 2026 · Updated Jul 14, 2026
An out-of-bounds read in Citrix Secure Access Client for Windows before 26.6.1.20 allows local users to disclose memory via an unspecified vector. Citrix has not published the affected component, triggering input, or operation that performs the out-of-bounds read. Exploitation requires standard-user access on the local Windows system and a configuration in which the DNE driver is not installed; the published impact is confidentiality loss only.
