CVE-2026-96578: CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in creative-solutions-1 GSpeech TTS – WordPress Text To Speech Plugin
The GSpeech TTS – WordPress Text To Speech Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content in all versions up to, and including, 3.22.0 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. This mXSS-style transform bypasses WordPress comment kses sanitization because the payload is stored using only kses-allowed tags and attributes; the malicious event handlers and style fragments become active only when the plugin's output-buffer callback rewrites the rendered HTML at request time.
AI Analysis
Technical Summary
CVE-2026-96578 is a stored Cross-Site Scripting vulnerability in the GSpeech TTS – WordPress Text To Speech Plugin affecting all versions up to and including 3.22.0. The flaw is due to improper neutralization of input during web page generation, specifically in comment content. Attackers can inject scripts that bypass WordPress's kses sanitization by leveraging allowed HTML tags and attributes. These scripts become active when the plugin rewrites the rendered HTML via an output-buffer callback during page requests, enabling execution of arbitrary web scripts without authentication.
Potential Impact
Successful exploitation allows unauthenticated attackers to execute arbitrary scripts in the context of users visiting the affected pages. This can lead to information disclosure, session hijacking, or other client-side impacts. The vulnerability has a CVSS 3.1 score of 7.2 (high severity), indicating significant risk to confidentiality and integrity but no impact on availability. There are no known exploits in the wild at this time.
Mitigation Recommendations
No official patch or fix is currently documented for this vulnerability. Users should monitor the vendor's advisory channels for updates. Until a fix is available, consider disabling the plugin or restricting comment functionality to trusted users to reduce exposure. Avoid relying solely on WordPress's default comment sanitization as it is bypassed by this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
