Key insight
This NVD entry only describes the vulnerability and provides no indication of active exploitation, an exploit, or additional attack tactics.
Description
CVE-2026-15201 affects Synology DiskStation Manager (DSM) in versions before 7.3.2-86009-5 and 7.4.1-90080-1. The Support Form function validates certificates insufficiently, allowing a man-in-the-middle attacker to read arbitrary files and write specific files during submission. Exploitation requires a MITM position between the client and the DSM. The NVD description contains no information about active exploitation, KEV listing, or a public PoC. Installations that use the Support Form and do not run the specified fixed versions are affected.
