CVE-2024-13844 (GCVE-0-2024-13844)

Vulnerability from nvd – Published: 2025-03-08 05:30 – Updated: 2026-04-08 16:33

Title

Post SMTP <= 3.1.2 - Authenticated (Administrator+) SQL Injection via columns Parameter

Summary

The Post SMTP plugin for WordPress is vulnerable to generic SQL Injection via the ‘columns’ parameter in all versions up to, and including, 3.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Severity

4.9 (Medium)

CVE-2025-0521 (GCVE-0-2025-0521)

Vulnerability from nvd – Published: 2025-02-18 11:10 – Updated: 2026-04-08 16:46

Title

Post SMTP <= 3.0.2 - Unauthenticated Stored Cross-Site Scripting

Summary

The Post SMTP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the from and subject parameter in all versions up to, and including, 3.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

CVE-2024-5207 (GCVE-0-2024-5207)

Vulnerability from nvd – Published: 2024-05-30 05:33 – Updated: 2026-04-08 16:35

Title

POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress <= 2.9.3 - Authenticated (Administrator+) SQL Injection

Summary

The POST SMTP – The #1 WordPress SMTP Plugin with Advanced Email Logging and Delivery Failure Notifications plugin for WordPress is vulnerable to time-based SQL Injection via the selected parameter in all versions up to, and including, 2.9.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with administrator access or higher to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Severity

7.2 (High)

CVE-2023-6875 (GCVE-0-2023-6875)

Vulnerability from nvd – Published: 2024-01-11 08:33 – Updated: 2026-04-08 17:30

Title

POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress <= 2.8.7 - Authorization Bypass via type connect-app API

Summary

The POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a type juggling issue on the connect-app REST endpoint in all versions up to, and including, 2.8.7. This makes it possible for unauthenticated attackers to reset the API key used to authenticate to the mailer and view logs, including password reset emails, allowing site takeover. CVE-2023-52233 appears to be a duplicate of this issue.

Severity

9.8 (Critical)

CVE-2023-7027 (GCVE-0-2023-7027)

Vulnerability from nvd – Published: 2024-01-03 04:29 – Updated: 2026-04-08 17:03

Title

POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress <= 2.8.7 - Unauthenticated Stored Cross-Site Scripting via device

Summary

The POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘device’ header in all versions up to, and including, 2.8.7 due to insufficient input sanitization and output escaping.

CVE-2023-3179 (GCVE-0-2023-3179)

Vulnerability from nvd – Published: 2023-07-17 13:29 – Updated: 2024-11-07 14:18

Title

POST SMTP Mailer < 2.5.7 - Account Takeover via CSRF

Summary

The POST SMTP Mailer WordPress plugin before 2.5.7 does not have proper CSRF checks in some AJAX actions, which could allow attackers to make logged in users with the manage_postman_smtp capability resend an email to an arbitrary address (for example a password reset email could be resent to an attacker controlled email, and allow them to take over an account).

Severity

No CVSS data available.

CVE-2024-13844 (GCVE-0-2024-13844)

Vulnerability from cvelistv5 – Published: 2025-03-08 05:30 – Updated: 2026-04-08 16:33

Title

Post SMTP <= 3.1.2 - Authenticated (Administrator+) SQL Injection via columns Parameter

Summary

The Post SMTP plugin for WordPress is vulnerable to generic SQL Injection via the ‘columns’ parameter in all versions up to, and including, 3.1.2 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Severity

4.9 (Medium)

Summary

The Post SMTP plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the from and subject parameter in all versions up to, and including, 3.0.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

CVE-2024-5207 (GCVE-0-2024-5207)

Vulnerability from cvelistv5 – Published: 2024-05-30 05:33 – Updated: 2026-04-08 16:35

Title

POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress <= 2.9.3 - Authenticated (Administrator+) SQL Injection

Summary

The POST SMTP – The #1 WordPress SMTP Plugin with Advanced Email Logging and Delivery Failure Notifications plugin for WordPress is vulnerable to time-based SQL Injection via the selected parameter in all versions up to, and including, 2.9.3 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers with administrator access or higher to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

Severity

7.2 (High)

CVE-2023-6875 (GCVE-0-2023-6875)

Vulnerability from cvelistv5 – Published: 2024-01-11 08:33 – Updated: 2026-04-08 17:30

Title

POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress <= 2.8.7 - Authorization Bypass via type connect-app API

Summary

The POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress plugin for WordPress is vulnerable to unauthorized access of data and modification of data due to a type juggling issue on the connect-app REST endpoint in all versions up to, and including, 2.8.7. This makes it possible for unauthenticated attackers to reset the API key used to authenticate to the mailer and view logs, including password reset emails, allowing site takeover. CVE-2023-52233 appears to be a duplicate of this issue.

Severity

9.8 (Critical)

CVE-2023-7027 (GCVE-0-2023-7027)

Vulnerability from cvelistv5 – Published: 2024-01-03 04:29 – Updated: 2026-04-08 17:03

Title

POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress <= 2.8.7 - Unauthenticated Stored Cross-Site Scripting via device

Summary

The POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘device’ header in all versions up to, and including, 2.8.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

CVE-2023-6629 (GCVE-0-2023-6629)

Vulnerability from cvelistv5 – Published: 2024-01-03 04:29 – Updated: 2026-04-08 17:01

Title

POST SMTP Mailer <= 2.8.6 - Reflected Cross-Site Scripting via msg

Summary

The POST SMTP Mailer – Email log, Delivery Failure Notifications and Best Mail SMTP for WordPress plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘msg’ parameter in all versions up to, and including, 2.8.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. CVE-2023-6621 appears to be a duplicate of this issue. CVE-2024-29128 appears to be a duplicate of this issue.
