Local privilege escalation via unsecured library search
Published Feb 20, 2026 · Updated Feb 20, 2026
Uncontrolled library search in PDF-XChange Co Ltd PDF-XChange Editor 10.7.2.400 allows local users to execute code via TrackerUpdate. TrackerUpdate loads a library from an unsecured location without constraining the search path, allowing attacker-controlled code to run in the target user context. Exploitation requires low-privileged local code execution and user interaction; success grants the affected target user's privileges.
