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 · uneditedImproper neutralization of special elements used in an SQL command ('SQL Injection') vulnerability in thumbnail component in Synology Photo Station before 6.8.14-3500 allows remote attackers users to execute arbitrary SQL commands via unspecified vectors.

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 checksWork through these to decide whether this CVE applies to you.
-
Confirm Photo Station is installedAccess your Synology NAS management interface and verify that Photo Station package is installed and runningAffected if Photo Station is installed and active on the system
-
Determine installed Photo Station versionLocate the Photo Station version information through the Synology Package Center or the Photo Station web interface settingsAffected if The version cannot be determined or is below 6.8.14-3500
-
Compare version against affected rangeCheck if the installed version falls within >= 6.8 and < 6.8.14-3500Affected if The installed version is 6.8 through 6.8.14-3499 (any version before 6.8.14-3500)
-
Verify thumbnail functionality is accessibleConfirm the Photo Station thumbnail generation feature is enabled and accessible to usersAffected if Thumbnail processing is enabled and the Photo Station web interface is reachable
You are affected if Photo Station is running with any version from 6.8 up to but not including 6.8.14-3500 and the thumbnail component is accessible.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped6.8.14-3500
Upgrade Synology Photo Station to version 6.8.14-3500 or later to obtain the vendor patch. If immediate patching is not possible, consider restricting network access to the Photo Station interface or disabling the thumbnail functionality as a temporary mitigation.
