Top Risky CVEs
| 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-2026-40541 | Stored/reflected cross-site scripting in Synology Chat Server before 2.4.5-22148 lets a remote authenticated user who lures a victim into a UI interaction execute injected script that pivots into the underlying DSM platform to read or write arbitrary files and trigger denial-of-service. The vendor-assigned CVSS 9.0 reflects a scope change (S:C) where compromise of the chat add-on cascades into the host DiskStation Manager operating system. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV. | CRITICAL | 9.0 | 0.5% | 45 |
|
| CVE-2025-30028 | Arbitrary file disclosure in Synology Active Backup for Business (DSM add-on package, versions before 2.7.1-3234) lets unauthenticated remote attackers read sensitive files on the host via a SQL injection flaw (CWE-89). The vulnerability scores CVSS 8.6 with a changed scope and high confidentiality impact, but EPSS estimates only a 0.04% (14th percentile) exploitation probability, and there is no public exploit identified at time of analysis nor any CISA KEV listing. Synology, who self-reported the issue, has released a fixed package. | HIGH | 8.6 | 0.0% | 43 |
|
| 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-2021-47961 | A plaintext storage of a password vulnerability in Synology SSL VPN Client before 1.4.5-0684 allows remote attackers to access or influence the user's PIN code due to insecure storage. Rated high severity (CVSS 8.1), this vulnerability is remotely exploitable, no authentication required, low attack complexity. | HIGH | 8.1 | 0.0% | 41 |
|
| CVE-2022-49036 | An inclusion of functionality from untrusted control sphere vulnerability in OpenSSL configuration in Synology Active Backup for Business Recovery Media Creator before 2.5.0-2081 allows local users. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. | HIGH | 7.8 | 0.0% | 39 |
|
| CVE-2022-49042 | An inclusion of functionality from untrusted control sphere vulnerability in MinGW DLL component in Synology Hyper Backup Explorer before 3.0.1-0156 allows local users to execute arbitrary code via. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. | HIGH | 7.8 | 0.0% | 39 |
|
| CVE-2023-52945 | Uncontrolled search path element vulnerability in OpenSSL DLL component in Synology BeeDrive for desktop before 1.3.2-13814 allows local users to execute arbitrary code via unspecified vectors. Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. | HIGH | 7.8 | 0.0% | 39 |
|
| 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-2026-4793 | Incorrect default permissions in Synology Assistant before version 7.0.7-50095 expose locally created installation artifacts to unauthorized access, enabling low-privileged local users to read or write arbitrary files and trigger denial-of-service conditions during the installation window. The CVSS score of 7.3 (High) with C:H/I:H/A:H reflects the breadth of potential file system impact, though an EPSS of 0.13% (3rd percentile) and SSVC exploitation status of 'none' confirm no public exploitation activity at time of analysis. A vendor-released patch exists at version 7.0.7-50095, and no public exploit code has been identified. | HIGH | 7.3 | 0.1% | 37 |
|
| CVE-2024-11399 | Files or directories accessible to external parties vulnerability in redis-server component in Synology BeeDrive for desktop before 1.3.2-13814 allows local users to conduct denial-of-service attacks. Rated medium severity (CVSS 6.8), this vulnerability is no authentication required, low attack complexity. | MEDIUM | 6.8 | 0.0% | 34 |
|
| CVE-2026-9548 | Cross-site scripting in Synology Chat Server's extract domain feature allows authenticated remote users to inject malicious scripts that execute upon victim UI interaction, with impact extending beyond the Chat application into the broader DSM (DiskStation Manager) environment. The scope change captured in the CVSS vector (S:C) is the key risk amplifier: successful exploitation can result in reading or writing restricted DSM files and conducting limited denial-of-service against DSM. No public exploit or CISA KEV listing has been identified at time of analysis; a vendor-released patch is available. | MEDIUM | 6.5 | 0.2% | 33 |
|
| CVE-2021-47960 | A files or directories accessible to external parties vulnerability in Synology SSL VPN Client before 1.4.5-0684 allows remote attackers to access files within the installation directory via a local. Rated medium severity (CVSS 6.5), this vulnerability is remotely exploitable, no authentication required, low attack complexity. | MEDIUM | 6.5 | 0.0% | 33 |
|
| 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-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 |
