CVE-2026-9148
HighCVSS 7.2Summary
The Comments – wpDiscuz plugin for WordPress up to version 7.6.56 is vulnerable to Stored Cross-Site Scripting. This is due to insufficient output escaping in the getCommentAuthor() function, which interpolates the stored comment_author_url value directly into single-quoted HTML attributes without applying esc_url() or esc_attr(). Unauthenticated attackers can inject arbitrary web scripts that execute whenever a user accesses an injected page.
Risk Assessment
An attacker can hijack user sessions, steal data, or redirect users to malicious sites, compromising the confidentiality and integrity of organizational data.
Recommendation
Immediately update the Comments – wpDiscuz plugin to the latest available version that includes a fix for this vulnerability.
