Summary

CVE-2026-111347 is a high-severity Use of Hard-coded Cryptographic Key (CWE-321) vulnerability in Hackmd (inferred from references). Its CVSS base score is 8.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Steganography (T1001.002); ranked at the 30th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified map to SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

Vulnerability Data

go-ldap-admin through 0.6.2 embeds a hard-coded RSA private key, published in the public repository, that protects encrypted login passwords. Unauthenticated attackers who capture encrypted passwords can decrypt them offline or via the /base/decryptpwd endpoint, recovering cleartext LDAP credentials for reuse.

SC-12 Cryptographic Key Establishment and Management partial match

Requiring cryptographic keys to be established and managed according to defined requirements prevents developers from embedding static unchangeable keys.

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.DS-01 partial match
blocks

Data-at-rest protection policies require proper key management and therefore discourage hard-coded keys.

PR.DS-02 partial match
blocks

Data-in-transit protection similarly depends on non-hard-coded keys for encryption.

PR.PS-01 partial match
blocks

Configuration baselines and reviews can prohibit hard-coded keys in deployed artifacts.

PR.PS-06 partial match

Secure-SDLC activities such as code review and secret scanning directly prevent embedding static keys.
