Summary
CVE-2026-22094 is a critical-severity Use of Weak Credentials (CWE-1391) vulnerability in Divd (inferred from references). Its CVSS base score is 9.3 (Critical).
Operationally, ranked at the 14th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to IA-5 (Authenticator Management) — see the control section below for these in your framework.

Vulnerability Data
The firmware for the EVbee DC-80 has a weak hardcoded root password, which allows attackers to login as root using the SSH daemon that is exposed to the network.

Mitigating Controls (NIST 800-53 r5) AI
IA-5 directly requires management of authenticator strength, distribution, and replacement, stopping default or guessable credentials from being introduced or used.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
PR.AA-01's credential issuance and key-management processes directly block most weak/default credential usage, yet leave hard-coded or product-design instances of CWE-1391 only partially addressed.
Password-strength policies in PR.AA-03 directly block weak authenticators, but the control leaves hard-coded/default credentials largely unaddressed.
Hardened baselines and default-setting reviews directly block default/hard-coded creds (mostly), yet leave algorithmic guessing, reuse, and non-config sources of weak credentials untouched (partial).
Training raises password-hygiene awareness and can therefore reduce some weak-credential mistakes, yet supplies no enforcement mechanism and leaves the dominant technical sources of CWE-1391 untouched.
Role-based awareness training can reduce the chance developers or admins introduce weak credentials but supplies no enforcement or verification, leaving the bulk of CWE-1391 risk untouched.
Maintenance/patching can incidentally remove known weak-default creds in updated versions (partial forward) but does nothing to ensure credentials are strong at design, deployment or config time (none reverse).

A.5.17 mandates generation of non-guessable unique credentials, immediate change of defaults/temporary secrets, strong password enforcement, no reuse, blocking of compromised passwords, and secure transmission/storage; this stops exploitation of weak/guessable/default credentials for most but not all cases in CWE-1391 (e.g. leaves some non-password credential forms or post-compromise reuse outside its explicit scope).
Restricts privileged accounts but does not explicitly address default or hard-coded credentials for those accounts.
Requires security activities throughout the SDLC that can catch weak credentials, but does not mandate their elimination.
Secure-coding rules can prohibit hard-coded passwords, yet coverage depends on specific coding standards adopted.
Security testing can discover weak credentials, but does not guarantee they are prevented by design.
A.8.5 mandates strong, multi-factor, non-guessable authentication techniques (with brute-force protection, no cleartext, etc.) that stop weak credentials from being successfully exploited; the bounded remainder is hard-coded/default credentials inside non-interactive product components where no human or session authentication occurs at all.
