Authenticator is a browser extension that generates two-step verification codes. In versions 7.0.0 and below, encryption keys for user data were stored encrypted at-rest using only AES-256 and the EVP_BytesToKey KDF. Therefore, attackers with a copy of a user's data are able to brute-force the user's encryption key. Users on version 8.0.0 and above are automatically migrated away from the weak encoding on first login. Users should destroy encrypted backups made with versions prior to 8.0.0.
CVE-2024-45394
This high-severity CVE scores 8.8 under NVD CVSS v3. EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
