HighCVE-2026-9148

Comments <= 7.6.56 - Unauthenticated Stored Cross-Site Scripting via 'Website' Field

Comments – wpDiscuz: Currently marked unpatched

Affected versions: *-7.6.56

Vulnerability type: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Affected software, patched versions and attribution

The Comments – wpDiscuz plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the guest commenter 'Website' field in versions up to, and including, 7.6.56 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(). This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

wpDiscuz <= 7.6.5 - Unauthenticated SQL Injection

Comments – wpDiscuz: Currently marked unpatched

Affected versions: [*, 7.6.6)

Vulnerability type: CWE-89 Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')

Affected software, patched versions and attribution

The wpDiscuz plugin for WordPress is vulnerable to SQL Injection via the 'visibleCommentIds' parameter in versions up to, and including, 7.6.5 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This requires the 'Live Update' functionality to be enabled for subscriber+ exploitation, and the 'Enable Live Update for Guests' setting enabled for unauthenticated exploitation.
