Volume encryption in Synology Storage Manager before version 1.0.1-1100 transmits sensitive data via HTTP GET query strings, exposing encryption-related secrets to local attackers who can access web server logs, browser history, or other locally readable URL artifacts. The flaw (CWE-598) requires no privileges or user interaction beyond local system presence, and carries a High confidentiality impact rating because credentials or passphrases associated with volume encryption may be recoverable from logged GET requests. No public exploit exists and EPSS sits at the 1st percentile, indicating no widespread exploitation activity at time of analysis.

Synology Assistant before version 7.0.6-50085 exposes local users to arbitrary file write with restricted content via an origin validation error triggered during the installation process. The CVSS vector (AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H) indicates that while integrity impact is limited, availability impact is rated High - meaning an attacker can corrupt or overwrite files in ways that destabilize the system, even though the written content is constrained. No public exploit code exists and CISA has not added this to KEV; EPSS stands at 0.00%, reflecting minimal observed exploitation interest.

Synology Active Backup for Business Agent before version 3.1.0-4967 contains an origin validation error (CWE-346) that permits local users to write arbitrary files with restricted content during the installation process, resulting in high availability impact and limited integrity compromise. The CVSS vector (AV:L/PR:N/UI:R) indicates exploitation requires local system access and user interaction - specifically, the installation must be in progress. No public exploit code has been identified and EPSS sits at 0.00%, aligning with SSVC's 'exploitation: none' assessment, indicating this is a low-urgency but legitimate local privilege abuse risk during deployment windows.

Credential disclosure in Synology C2 Identity Edge Server (DSM versions before 1.76.0-0307) allows remote unauthenticated attackers to retrieve user credentials directly from the edge server over the network. The flaw stems from an exposed dangerous method/function (CWE-749) reachable without authentication, yielding a high-confidentiality impact with no integrity or availability effect. No public exploit has been identified at time of analysis, and EPSS scores it at the bottom 7th percentile, indicating low near-term exploitation likelihood despite the network-reachable vector.

Arbitrary file write with restricted content in Synology ActiveProtect Agent before 1.1.0-0439 is exploitable by local users during the installation process due to an origin validation error (CWE-346). The CVSS vector (AV:L/AC:L/PR:N/UI:R) indicates a low-complexity local attack requiring user interaction - consistent with exploitation during an installation workflow - and scores high on availability impact (A:H) while integrity impact is limited (I:L), suggesting the file write can disrupt system stability despite content restrictions. No public exploit code exists and CISA SSVC rates exploitation as none with partial technical impact.

Authentication bypass in Synology DiskStation Manager (DSM) SSO lets remote, unauthenticated attackers who already know a valid account's distinguished name (DN) impersonate that identity and gain access to the NAS, with high confidentiality, integrity, and availability impact (CVSS 8.1). The flaw stems from an improper check of an exceptional condition (CWE-754) in the single sign-on flow. There is no public exploit identified at time of analysis, and the EPSS probability is very low (0.05%, 17th percentile), consistent with the high attack complexity Synology assigned.

Cross-site scripting in Synology Contacts before version 1.0.10-20659 allows authenticated remote users to read or write specific files containing non-sensitive information by injecting malicious input through the contact functionality. The CVSS scope change (S:C) confirms the injected script executes in a context beyond the originating application, affecting any victim who views the crafted contact entry. No public exploit identified at time of analysis, and CISA has not listed this in the Known Exploited Vulnerabilities catalog.

Remote code execution in Synology BeeStation OS versions before 1.3.2-65648 stems from a classic buffer overflow in the AdminCenter component, the device's web-based management interface. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) indicates a network-reachable flaw exploitable by unauthenticated attackers with low complexity and no user interaction, yielding full compromise of confidentiality, integrity, and availability (9.8 Critical). There is no public exploit identified at time of analysis, and the issue is not listed in CISA KEV, but the unauthenticated network-RCE profile on a consumer NAS device makes this a high-priority patch target.

Stored XSS in Synology Safe Access before 1.3.1-0329 on SRM (Synology Router Manager) allows remote authenticated administrators to inject malicious scripts that execute in the SRM context, enabling limited reads or writes of non-sensitive files and constrained denial-of-service conditions. The CVSS Scope:Changed rating confirms cross-component impact - the vulnerability originates in the Safe Access module but affects the broader SRM platform. No public exploit code exists and no active exploitation has been identified; EPSS at 0.03% and SSVC exploitation status of 'none' collectively indicate negligible current threat in the wild.

OpenClaw before 2026.4.22 allows workspace dotenv files to override connector endpoint hosts for Matrix, Mattermost, IRC, and Synology connectors, enabling local attackers with workspace access to redirect runtime traffic to malicious endpoints. The vulnerability requires local access and user interaction but allows high confidentiality impact through traffic interception. No active exploitation has been identified, but a vendor-released patch is available.

OpenClaw before 2026.3.22 contains a webhook path route replacement vulnerability in its Synology Chat extension that allows unauthenticated remote attackers to bypass per-account direct message access controls by collapsing multi-account configurations onto shared webhook paths. Attackers can exploit inherited or duplicate webhook paths to replace route ownership across accounts, potentially gaining unauthorized access to account-specific resources. No public exploit code or active exploitation has been confirmed at the time of analysis.

Synology OpenClaw versions prior to 2026.2.24 contain an authorization bypass in the synology-chat channel plugin where misconfigured allowlist policies with empty user IDs fail to enforce access controls. Authenticated attackers with Synology sender privileges can exploit this flaw to send unauthorized messages through downstream agents and tools. A patch is available.

Synology OpenClaw versions 2026.2.22 and 2026.2.23 contain an authorization bypass in the synology-chat channel plugin where misconfigured allowlist policies with empty user IDs fail open, allowing authenticated Synology senders to dispatch unauthorized agents and execute downstream tool actions. The vulnerability requires network access and low-complexity exploitation, with a patch currently available.

Synology Presto Client versions prior to 2.1.3-0672 are vulnerable to DLL hijacking during installation, enabling local attackers with user privileges to read or write arbitrary files by placing malicious libraries in the installer directory.
