At a glance
CVE-2026-97397 is a high-severity Improper Neutralization of Input During Web Page Generation vulnerability in the Remove Google Fonts WordPress plugin, affecting versions <= 1.7. It carries a CVSS score of 7.2 (reachable over the network; low attack complexity). Exploitation requires no authentication. No fixed release has been reported yet; treat installations running this software as exposed. Disclosed November 2026, reported by theviper17y.
Vulnerability Overview
The Remove Google Fonts – Disable, Block, or Replace with Bunny Fonts for GDPR Compliance plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Field via Regex-Mangled Output Buffer in all versions up to, and including, 1.7 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires the plugin's Remove mode to be active and the malicious comment to be published, either through auto-approval for known commenters or manual moderator approval.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation
Reaching this weakness in Remove Google Fonts <= 1.7 takes no account at all. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.
Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. No fixed build of this plugin is recorded for Remove Google Fonts yet, so installs running <= 1.7 stay exposed until the vendor ships one.
Remediation
No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.
How does WordSec protect against this?
Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
