CVE-2026-96768 Details
Description
The GoSMTP Pro plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Content via Email Log Body in all versions up to, and including, 1.2.3 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. The exploit is made possible because WordPress comment kses does not strip entity-encoded tag delimiters, allowing the payload to pass moderation as safe text before being decoded into live HTML by core email notification functions and written verbatim into the plugin's email log database table.
A stored cross-site scripting vulnerability has been identified in the GoSMTP Pro plugin for WordPress, affecting all versions through 1.2.3. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary scripts into pages. These scripts execute when a user accesses the compromised page. The vulnerability exploits WordPress's comment moderation system, which fails to remove entity-encoded tag delimiters, enabling malicious payloads to bypass moderation as safe text. Once decoded into HTML by core email notification functions, the scripts are logged into the plugin's email log database table, where they can be executed.
Users are advised to update the GoSMTP Pro plugin to version 1.2.4 or a newer patched version.
