Administrator-only limited file write
Published May 27, 2026 · Updated May 27, 2026
Improper permission preservation in Surveillance Station allows remote authenticated users with administrator privileges to write limited files. The Archiving Push functionality fails to preserve permissions during an unspecified file operation, but Synology has not disclosed the affected code or input vector. Exploitation requires administrator privileges, and the published impact is limited to file integrity with no reported read, execution, or service-interruption capability.
