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 attackers to obtain sensitive information. The flaw, identified as CWE-598, stems from the web application’s use of the HTTP GET method to process a request and includes sensitive information in the query string of that request. For volume encryption functionality, which relies on Linux Unified Key Setup (LUKS), sensitive parameters such as encryption keys or vault passwords are transmitted as part of the URL query string. A local attacker can monitor HTTP traffic or inspect logs to capture these query strings. The attack complexity is low, requires local access, no privileges, and no user interaction. The vulnerability is classified as problematic with a CVSS 3.1 base score of 6.2. It was discovered by Simon Baaske and addressed by Synology in advisory Synology-SA-26:01, with a fixed version released on February 9, 2026.
DailyCVE Form:
Platform: Synology DSM
Version: <1.0.1-1100
Vulnerability: CWE-598
Severity: Medium
date: 2026-05-27
Prediction: 2026-02-09
What Undercode Say:
Identify vulnerable Storage Manager version synopkg version StorageManager Simulate capturing GET requests with sensitive data grep -r "encryption_key" /var/log/
GET /webapi/entry.cgi?api=SYNO.Storage.Volume.Encryption&method=unlock&volume_id=vol1&encryption_key=SUPERSECRETKEY HTTP/1.1 Host: 192.168.1.100
Exploit:
A local attacker with access to the Synology NAS can monitor HTTP traffic to the Storage Manager web API. By capturing GET requests, the attacker can extract sensitive information such as encryption keys or vault passwords from the query string.
Protection:
Update Storage Manager to version 1.0.1-1100 or above. Restrict local access to trusted users only. Use encrypted channels (HTTPS) and consider network monitoring to detect anomalous activity.
Impact:
Successful exploitation leads to disclosure of sensitive information, compromising the confidentiality of encrypted volumes. This could allow an attacker to decrypt volumes without authorization.
