CVE Summary Severity CVSS EPSS Priority Signals
CVE-2025-12686 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. CRITICAL 9.8 0.2% 49
CVE-2024-45538 Cross-Site Request Forgery (CSRF) vulnerability in WebAPI Framework in Synology DiskStation Manager (DSM) before 7.2.1-69057-2 and 7.2.2-72806 and Synology Unified Controller (DSMUC) before 3.1.4-23079 allows remote attackers to execute arbitrary code via unspecified vectors. CRITICAL 9.6 0.1% 48
CVE-2026-31998 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. HIGH 8.3 0.0% 42
CVE-2025-13392 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. HIGH 8.1 0.1% 41
CVE-2025-54160 Improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability in BeeDrive in Synology BeeDrive for desktop before 1.4.2-13960 allows local users to execute arbitrary code via unspecified vectors. HIGH 7.8 0.0% 39
CVE-2025-54158 Missing authentication for critical function vulnerability in BeeDrive in Synology BeeDrive for desktop before 1.4.2-13960 allows local users to execute arbitrary code via unspecified vectors. HIGH 7.8 0.0% 39
CVE-2024-45539 Out-of-bounds write vulnerability in cgi components in Synology DiskStation Manager (DSM) before 7.2.1-69057-2 and 7.2.2-72806 and Synology Unified Controller (DSMUC) before 3.1.4-23079 allows remote attackers to conduct denial-of-service attacks via unspecified vectors. HIGH 7.5 0.2% 38
CVE-2025-54159 Missing authorization vulnerability in BeeDrive in Synology BeeDrive for desktop before 1.4.2-13960 allows remote attackers to delete arbitrary files via unspecified vectors. HIGH 7.5 0.1% 38
CVE-2025-14713 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. HIGH 7.5 0.0% 38
CVE-2026-3091 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. The vulnerability requires user interaction and local access but grants high-impact capabilities including confidentiality and integrity violations. No patch is currently available. MEDIUM 6.7 0.0% 34
No patch
CVE-2026-32911 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. MEDIUM 6.4 – 32
CVE-2025-2848 A vulnerability in Synology Mail Server allows remote authenticated attackers to read and write non-sensitive settings, and disable some non-critical functions. MEDIUM 6.3 0.1% 32
CVE-2026-35635 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. MEDIUM 6.3 0.0% 32
CVE-2026-2237 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. MEDIUM 6.2 0.0% 31
CVE-2025-13593 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. MEDIUM 6.1 0.0% 31
