Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: High: The attacker is authorized with (i.e., requires) privileges that provide significant (e.g., administrative) control over the vulnerable component that could affect component-wide settings and files.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

Until a fix is available, restrict administrative access to trusted users only and monitor for any unauthorized access. Consider removing or disabling the plugin if SMTP password exposure is a concern. Follow up with the vendor or WPForms for updates regarding a security patch.

Description

The WP Mail SMTP plugin for WordPress is vulnerable to information exposure in all versions up to, and including, 4.0.1. This is due to plugin providing the SMTP password in the SMTP Password field when viewing the settings. This makes it possible for authenticated attackers, with administrative-level access and above, to view the SMTP password for the supplied server. Although this would not be useful for attackers in most cases, if an administrator account becomes compromised this could be useful information to an attacker in a limited environment.

Impact

An attacker who has already obtained administrative-level access to a WordPress site with the vulnerable plugin can view the SMTP password in plain text. This could potentially allow further misuse of the SMTP credentials if the attacker leverages them outside the WordPress environment. However, since administrative access is required to exploit this vulnerability, the impact is limited to scenarios where the attacker already has significant control over the site.

Summary

CVE-2024-6694 affects the WP Mail SMTP plugin by WPForms, where the SMTP password is displayed in plain text within the plugin's settings page for all versions up to 4.0.1. This allows any authenticated user with administrative-level access or higher to retrieve the SMTP password. The vulnerability is categorized under CWE-257, indicating improper storage or exposure of passwords in a recoverable format. The issue does not affect users without high privileges and does not impact confidentiality beyond the SMTP password exposure. There are no known exploits in the wild, and the CVSS v3.1 base score is 2.7, indicating low severity.

CWE-257Storing Passwords in a Recoverable Format (opens in a new tab)
Base weaknessLikelihood of exploit: HighOWASP Top 10 A04:2021: Insecure Design (opens in a new tab)
The storage of passwords in a recoverable format makes them subject to password reuse attacks by malicious users. In fact, it should be noted that recoverable encrypted passwords provide no significant benefit over plaintext passwords since they are subject not only to reuse by malicious attackers but also by malicious insiders. If a system administrator can recover a password directly, or use a brute force search on the available information, the administrator can use the password on other accounts.
Architecture and Design
Use strong, non-reversible encryption to protect stored passwords.
