Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Relative path traversal vulnerability in SYNO.PhotoTeam.Upload.Item in Synology Moments before 1.3.0-0691 allows remote authenticated users to upload arbitrary files via the name parameter.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Relative path traversal vulnerability in Synology Moments upload component (SYNO.PhotoTeam.Upload.Item) allows authenticated users to manipulate the 'name' parameter to write files to arbitrary filesystem locations, potentially enabling remote code execution if writable web directories are targeted.

MitigationUpgrade Synology Moments to version 1.3.0-0691 or later to obtain the patched code with proper path sanitization.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Verify Synology Moments is installed
    Check the package center or installed applications on the Synology NAS to confirm Synology Moments is present
    Affected if Synology Moments is not installed on the system
  2. Identify installed Synology Moments version
    In Synology Package Center, view the installed package details for Synology Moments to find the exact version number (such as 1.3.0-0xxx or earlier)
    Affected if Unable to determine the installed version from package information
  3. Compare version against affected range
    Compare the installed version number to 1.3.0-0691 - any version less than 1.3.0-0691 falls within the affected range
    Affected if Installed version is lower than 1.3.0-0691 (for example, 1.3.0-0532 or 1.2.9-xxxx)
  4. Confirm web interface accessibility
    Verify that the Synology Moments web interface is accessible and exposed (typically at /moments/ or port 80/443)
    Affected if The Moments web interface is publicly or internally accessible over HTTP/HTTPS

If Synology Moments is installed with a version lower than 1.3.0-0691 and the web interface is accessible, the environment is affected by this path traversal vulnerability.
