|---|---|---|---|---|---|---|
| CVE-2026-7807 | SmarterTools SmarterMail builds prior to 9560 contain a local file inclusion vulnerability in the /api/v1/report/summary/{type} API endpoint that allows authenticated users to read arbitrary .json files on the system. Attackers can exploit this vulnerability combined with weak encryption algorithms and hardcoded keys to decrypt and access stored passwords and 2FA secrets for all users. | [email protected] | 8.7 | 0.30% | 2026-05-08 | 2026-06-17 |
| CVE-2026-40514 | SmarterTools SmarterMail builds prior to 9610 contain a cryptographic weakness in the file and email sharing endpoints that use DES-CBC encryption with keys and initialization vectors derived from System.Random seeded with insufficient entropy, reducing the seed space to approximately 19,000 possible values. An unauthenticated attacker can use the attachment download endpoint as an oracle to determine the seed in use and derive encryption keys and initialization vectors to forge sharing tokens f | [email protected] | 8.2 | 0.15% | 2026-04-27 | 2026-06-17 |
| CVE-2026-25067 | SmarterTools SmarterMail versions prior to build 9518 contain an unauthenticated path coercion vulnerability in the background-of-the-day preview endpoint. The application base64-decodes attacker-supplied input and uses it as a filesystem path without validation. On Windows systems, this allows UNC paths to be resolved, causing the SmarterMail service to initiate outbound SMB authentication attempts to attacker-controlled hosts. This can be abused for credential coercion, NTLM relay attacks, an | [email protected] | 6.9 | 0.28% | 2026-01-29 | 2026-06-17 |
| CVE-2026-24423 KEV | SmarterTools SmarterMail versions prior to build 9511 contain an unauthenticated remote code execution vulnerability in the ConnectToHub API method. The attacker could point the SmarterMail to the malicious HTTP server, which serves the malicious OS command. This command will be executed by the vulnerable application. | [email protected] | 9.3 | 87.69% | 2026-01-23 | 2026-06-17 |
| CVE-2026-23760 KEV | SmarterTools SmarterMail versions prior to build 9511 contain an authentication bypass vulnerability in the password reset API. The force-reset-password endpoint permits anonymous requests and fails to verify the existing password or a reset token when resetting system administrator accounts. An unauthenticated attacker can supply a target administrator username and a new password to reset the account, resulting in full administrative compromise of the SmarterMail instance.

| CVE-2023-48115 | SmarterTools SmarterMail 8495 through 8664 before 8747 allows stored DOM XSS because an XSS protection mechanism is skipped when messageHTML and messagePlainText are set in the same request. | [email protected] | 5.4 | 0.36% | 2023-12-21 | 2026-06-17 |
| CVE-2023-48114 | SmarterTools SmarterMail 8495 through 8664 before 8747 allows stored XSS by using image/svg+xml and an uploaded SVG document. This occurs because the application tries to allow youtube.com URLs, but actually allows youtube.com followed by an @ character and an attacker-controlled domain name. | [email protected] | 5.4 | 0.36% | 2023-12-21 | 2026-06-17 |
| CVE-2021-43977 | SmarterTools SmarterMail 16.x through 100.x before 100.0.7803 allows XSS. | [email protected] | 6.1 | 0.57% | 2021-11-17 | 2026-06-17 |
| CVE-2021-32234 | SmarterTools SmarterMail 16.x through 100.x before 100.0.7803 allows remote code execution. | [email protected] | 9.8 | 2.09% | 2021-11-17 | 2026-06-16 |
| CVE-2021-40377 | SmarterTools SmarterMail 16.x before build 7866 has stored XSS.

| CVE-2019-7214 | SmarterTools SmarterMail 16.x before build 6985 allows deserialization of untrusted data. An unauthenticated attacker could run commands on the server when port 17001 was remotely accessible. This port is not accessible remotely by default after applying the Build 6985 patch. | [email protected] | 9.8 | 84.82% | 2019-04-24 | 2026-06-16 |
| CVE-2019-7213 | SmarterTools SmarterMail 16.x before build 6985 allows directory traversal. An authenticated user could delete arbitrary files or could create files in new folders in arbitrary locations on the mail server. This could lead to command execution on the server for instance by putting files inside the web directories. | [email protected] | 6.5 | 42.11% | 2019-04-24 | 2026-06-16 |
| CVE-2019-7212 | SmarterTools SmarterMail 16.x before build 6985 has hardcoded secret keys. An unauthenticated attacker could access other users’ emails and file attachments. It was also possible to interact with mailing lists. | [email protected] | 8.2 | 1.01% | 2019-04-24 | 2026-06-16 |

| CVE-2015-9276 | SmarterTools SmarterMail before 13.3.5535 was vulnerable to stored XSS by bypassing the anti-XSS mechanisms. It was possible to run JavaScript code when a victim user opens or replies to the attacker's email, which contained a malicious payload. Therefore, users' passwords could be reset by using an XSS attack, as the password reset page did not need the current password. | [email protected] | 6.1 | 1.12% | 2019-01-16 | 2026-06-16 |
| CVE-2012-2578 | Multiple cross-site scripting (XSS) vulnerabilities in SmarterMail 9.2 allow remote attackers to inject arbitrary web script or HTML via an e-mail message body with (1) a JavaScript alert function used in conjunction with the fromCharCode method, (2) a SCRIPT element, (3) a Cascading Style Sheets (CSS) expression property in the STYLE attribute of an arbitrary element, or (4) an innerHTML attribute within an XML document. | [email protected] | 4.3 | 2.47% | 2012-09-19 | 2026-06-16 |
