A use of get request method with sensitive query strings vulnerability in volume encryption of Synology Storage Manager package before 1.0.1-1100 allows local users on Windows to obtain sensitive information.
Security readout for executives and security teams
Plain-English summary
Synology Storage Manager used GET requests that exposed sensitive volume-encryption information in query strings. On Windows, a local user could obtain that information. The supplied record describes confidentiality impact only and affects Storage Manager before 1.0.1-1100.
Executive priority
Prioritize routine but prompt remediation where Synology Storage Manager handles encrypted volumes. Business urgency is moderate because impact is sensitive-information disclosure, but exploitation requires local Windows access based on the supplied record.
Technical view
CVE-2026-2237 is a CWE-598 issue in Synology Storage Manager volume encryption. Sensitive values are sent in URL query strings via GET. CVSS 3.1 is 6.2 with local attack vector, low complexity, no privileges, no user interaction, and high confidentiality impact.
Likely exposure
Exposure appears limited to environments using Synology Storage Manager before 1.0.1-1100, specifically where Windows local users can access affected traces or artifacts. The sources do not identify remote exposure.
Exploitation context
The CVE is not listed as KEV in the supplied data. No cited source states active exploitation or public weaponization. The main risk is local disclosure of sensitive volume-encryption-related information.
Researcher notes
Evidence is concise and vendor-referenced. The record does not specify exact leaked fields, storage locations, or post-exposure impact. Avoid assuming remote reachability or exploit availability without additional vendor or telemetry evidence.
Mitigation direction
Upgrade Synology Storage Manager to 1.0.1-1100 or later per Synology guidance.
Review Synology advisory Synology-SA-26:01 for package-specific update instructions.
Limit local Windows access to systems managing affected Synology storage.
Treat potentially exposed volume-encryption secrets as sensitive and rotate if vendor guidance recommends it.
Validation and detection
Inventory Synology Storage Manager package versions in use.
Confirm affected installations are upgraded beyond versions before 1.0.1-1100.
Check whether Windows local users had access to affected management systems.
Review vendor advisory for any additional affected-version or remediation details.

Use the exact CWE identifier as the starting point before reviewing related ATT&CK behavior. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Use of HTTP Request With Sensitive Query String
Use of HTTP Request With Sensitive Query String represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
