CVE-2026-35467Network attack vector

API key disclosure via extractable IndexedDB private key

Published Apr 2, 2026 · Updated Apr 2, 2026

Credential exposure in CERT/CC cveClient before 1.1.15 allows attackers to extract the private key protecting stored API keys. save_key() stores the RSA private key in IndexedDB as an extractable JWK, allowing browser-context script or the JavaScript console to export it. Access to the browser context is required; the exported private key can decrypt locally stored API credentials.
