1.7.1
A Cross-Site Request Forgery (XSRF) vulnerability exists in the DX Unanswered Comments plugin for WordPress, affecting versions up to and including 1.7. This flaw allows unauthenticated attackers to manipulate plugin settings, potentially impacting comment management and author lists. The vulnerability stems from a lack of nonce validation within the plugin's settings form. Updating to a patched version is crucial to remediate this security risk.
An attacker can exploit this XSRF vulnerability to manipulate the DX Unanswered Comments plugin's configuration without authentication. By crafting a malicious link and enticing a site administrator to click it, an attacker can silently alter the dxucauthorslist and dxuccommentcount settings. This could lead to unexpected behavior, potentially impacting comment moderation workflows or even introducing unwanted content. While the impact is not as severe as a Remote Code Execution (RCE) vulnerability, it represents a significant risk to WordPress sites relying on this plugin for comment management.
CVE-2026-4138 was publicly disclosed on 2026-04-21. There are currently no known public proof-of-concept exploits available. The vulnerability is not listed on the CISA KEV catalog. Given the relatively low CVSS score and lack of public exploits, the probability of active exploitation is currently considered low.
WordPress websites utilizing the DX Unanswered Comments plugin, particularly those with administrative accounts that are susceptible to phishing or social engineering attacks, are at risk. Shared hosting environments where multiple websites share the same server resources could also be indirectly affected if one site is compromised and used to launch attacks against others.
