CVE-2026-89278Network attack vector

API key disclosure via reversible frontend encoding

Published Sep 18, 2026 · Updated Sep 18, 2026

Sensitive information exposure in GPTranslate 2.34.6 and earlier allows remote attackers to obtain third-party AI provider API keys. The enqueue_frontend_scripts function emits a reversibly encoded key into public inline JavaScript and supplies the inverse transform client-side. Any public page exposes the credential by default for non-DeepSeek providers unless supported GPT models use server-proxy mode, enabling billed API use.
