CVE-2026-79939

Script injection via followed symbolic links

Published Aug 26, 2026 · Updated Aug 27, 2026

UNIX symlink following in Dell PowerProtect Cyber Recovery before 20.3 allows local users to inject scripts through crafted filesystem links. Dell has not disclosed the affected component, pathname-handling routine, or the operation that follows an attacker-controlled link. Exploitation requires low-privileged local access and high-complexity conditions; Dell reports script injection but does not define its execution context.
