CVE-2023-6811Network attack vector

Stored XSS via unescaped api_key output

Published Apr 11, 2024 · Updated Apr 8, 2026

Stored XSS in ConveyThis Translate for WordPress 223 and earlier allows remote attackers to inject scripts through the api_key parameter. The plugin stores api_key input without sufficient sanitization and later emits the value into page output without context-appropriate escaping. No authentication is required to plant the payload, but execution occurs only when a user accesses an injected page, exposing that user's browser session to attacker-controlled code.
