Source: CVE Database V5
Vendor/Project: dr_scythe
Product: WP Email Debug

Description

The WP Email Debug plugin for WordPress is vulnerable to privilege escalation due to a missing capability check on the WPMDBUG_handle_settings() function in versions 1.0 to 1.1.0. This makes it possible for unauthenticated attackers to enable debugging and send all emails to an attacker controlled address and then trigger a password reset for an administrator to gain access to an administrator account.

Technical Analysis

CVE-2025-5486 is a critical security vulnerability affecting the WP Email Debug plugin for WordPress, specifically versions 1.0 through 1.1.0. The vulnerability arises from a missing authorization check (CWE-862) in the WPMDBUG_handle_settings() function, which fails to verify user capabilities before allowing access to sensitive debugging features. This flaw enables unauthenticated attackers to activate email debugging functionality, redirecting all outgoing emails to an attacker-controlled address. Exploiting this, an attacker can intercept password reset emails intended for administrators, allowing them to reset the administrator password and gain full administrative control over the WordPress site. The vulnerability has a CVSS 3.1 base score of 9.8, indicating critical severity with network attack vector, no privileges required, no user interaction needed, and high impact on confidentiality, integrity, and availability. Although no public exploits have been reported yet, the ease of exploitation and the potential for complete site takeover make this a highly dangerous threat. The vulnerability affects a widely used WordPress plugin, which is commonly deployed across many websites for email debugging purposes, increasing the attack surface. The lack of a patch at the time of publication further exacerbates the risk, necessitating immediate attention from site administrators.

Potential Impact

For European organizations, this vulnerability poses a significant risk, especially for those relying on WordPress for their web presence and using the WP Email Debug plugin. Successful exploitation can lead to unauthorized administrative access, enabling attackers to manipulate website content, steal sensitive data, deploy malware, or disrupt services. This can result in reputational damage, regulatory non-compliance (e.g., GDPR violations due to data breaches), financial losses, and operational disruptions. Organizations in sectors such as e-commerce, government, healthcare, and finance are particularly vulnerable due to the sensitive nature of their data and the criticality of their online services. Additionally, the ability to intercept password reset emails could facilitate lateral movement within an organization's network if the WordPress admin credentials overlap with other systems. The attack requires no authentication or user interaction, increasing the likelihood of automated exploitation attempts targeting European websites.

Mitigation Recommendations

Immediate mitigation steps include disabling or uninstalling the WP Email Debug plugin until a security patch is released. Organizations should audit their WordPress installations to identify the presence of this plugin and verify the version in use. If upgrading to a patched version becomes available, prompt application of the update is essential. In the interim, implementing web application firewall (WAF) rules to block unauthorized access to the plugin's endpoints, especially the WPMDBUG_handle_settings() function, can reduce exposure. Monitoring outgoing email logs for unusual redirection or unexpected recipients can help detect exploitation attempts. Additionally, enforcing multi-factor authentication (MFA) on WordPress administrator accounts can mitigate the impact of compromised credentials. Regular backups and incident response plans should be reviewed and tested to ensure rapid recovery in case of compromise. Finally, organizations should educate their IT teams about this vulnerability and encourage vigilance for suspicious activity related to WordPress administration.
