CVE-2026-89278

GPTranslate <= 2.34.6 - Unauthenticated Sensitive Information Exposure in Public Frontend Inline Script

State: Published
Severity: 5.3 Medium

Description

The GPTranslate – Multilingual AI Translation Agent for WordPress: Translate Your Site with AI plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.34.6 via the enqueue_frontend_scripts. This makes it possible for unauthenticated attackers to extract the plaintext third-party AI provider API key (OpenAI, DeepL, xAI/Grok, Gemini, Claude, or Google Cloud Translation) — a credential granting billed account access — by fetching any public page and applying the inverse transformation bundled in the plugin's own public JavaScript asset. This exposure affects the default configuration (gpt-3.5-turbo in client mode) and all supported non-DeepSeek providers; only deepseek-* models and gpt-* models configured in server-proxy mode correctly suppress key emission.
