- CVE-2026-70463: parse "auth users" with conf_strtok so a leading comma splits on commas alone, restoring "@Group Name" deny/:ro rules that whitespace tokenisation had silently discarded (authorization bypass) - CVE-2026-53786: strip the module_dir prefix before checking a client-supplied --filter merge file against daemon_filter_list, so module filter rules can no longer be bypassed - CVE-2026-70459: reject a non-directory "." / "/." transfer-root file-list entry and require dir_flist to hold an entry before trusting parent_ndx 0, fixing the wild-pointer read that crashed the daemon child - CVE-2026-53789: force implied-parent directories non-content on the receiver, including the synthetic transfer root and the legacy protocol < 30 XMIT_TOP_DIR path, so a malicious sender cannot widen --delete scope
