CVE-2026-2112 in Dam Spam Plugin
Summary
by MITRE • 02/18/2026
The Dam Spam plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 1.0.8. This is due to missing nonce verification on the pending comment deletion action in the cleanup page. This makes it possible for unauthenticated attackers to delete all pending comments via a forged request granted they can trick an admin into performing an action such as clicking on a link.

The Dam Spam plugin for WordPress presents a critical cross-site request forgery vulnerability that affects all versions up to and including 1.0.8. This vulnerability stems from the absence of proper nonce verification within the cleanup page's pending comment deletion functionality, creating a significant security gap that undermines the integrity of the plugin's administrative operations. The flaw resides in the plugin's failure to implement proper authentication checks before executing destructive actions, thereby exposing administrators to potential manipulation through maliciously crafted requests.
This CSRF vulnerability operates by exploiting the trust relationship between the WordPress admin interface and the Dam Spam plugin. When an administrator visits a page containing a malicious link or embedded payload, the forged request can automatically trigger the deletion of pending comments without requiring authentication or explicit user confirmation. The attack vector relies on social engineering techniques where attackers trick administrators into visiting compromised websites or clicking on malicious links, leveraging the administrator's existing authenticated session to perform unauthorized actions. The vulnerability specifically targets the cleanup page functionality, which is designed to manage pending comments but lacks the necessary security controls to prevent unauthorized manipulation.
The operational impact of this vulnerability extends beyond simple comment deletion, as it represents a fundamental breakdown in the plugin's security architecture. Attackers can potentially disrupt content moderation workflows, remove valuable user feedback, and compromise the integrity of comment management systems within WordPress installations. This vulnerability affects the principle of least privilege and violates the security principle that administrative actions should require explicit confirmation and authentication. The consequences include potential data loss, disruption of community engagement features, and possible escalation to more severe attacks if the compromised plugin serves as a foothold for further exploitation.
Mitigation strategies should focus on immediate patching of the Dam Spam plugin to version 1.0.9 or later, which addresses the nonce verification deficiency. Administrators must also implement additional security measures including regular plugin updates, monitoring of suspicious administrative activities, and implementation of web application firewalls that can detect and block CSRF attempts. The vulnerability aligns with CWE-352, which specifically addresses cross-site request forgery weaknesses, and maps to ATT&CK technique T1213.002 for credential access through manipulation of web applications. Organizations should also consider implementing multi-factor authentication for administrative accounts and conducting regular security audits of installed plugins to identify similar vulnerabilities. The incident underscores the importance of proper input validation and authentication mechanisms in web applications, particularly those handling administrative functions that can impact system integrity and user data.
