Threat Classification
This threat is classified as a critical vulnerability (HIGH CONFIDENCE) affecting the software sector, with a global geographic scope. The exploitation status is theoretical, as there is no indication of active exploitation in the wild (MEDIUM CONFIDENCE). The attacker motivation is likely to gain unauthorized access to sensitive information (HIGH CONFIDENCE), given the nature of the vulnerability.
Threat Severity Assessment
- Exploitability: CRITICAL, due to the ease of exploiting hard-coded cryptographic keys (HIGH CONFIDENCE).
- Scope of impact: HIGH, as it affects multiple versions of the HUMANIST Digital Human Resources software (HIGH CONFIDENCE).
- Prevalence: MEDIUM, as the vulnerability is specific to certain versions of the software (MEDIUM CONFIDENCE).
- CVSS score: 9.1, indicating a critical severity vulnerability (HIGH CONFIDENCE).
Business Impact
The potential business impact of this vulnerability includes operational disruption, as unauthorized access to sensitive information could lead to data breaches or system compromises. Regulatory liability is also a concern, particularly under GDPR, NIS2, DORA, and SOC 2, with potential penalties ranging from 2% to 4% of global turnover. Financial exposure is significant, given the potential for data breaches and system compromises. Reputational damage is also a risk, as organizations that fail to address the vulnerability may be seen as neglecting cybersecurity.
Technical Analysis
The attack vector for this vulnerability is the use of a hard-coded cryptographic key in the HUMANIST Digital Human Resources software. The exploitation chain involves reading sensitive constants within an executable, potentially allowing attackers to gain unauthorized access to sensitive information. The affected component is the HUMANIST Digital Human Resources software, specifically versions from 26.0 before 26.1. The root cause is the use of a hard-coded cryptographic key, classified as a CWE-321 vulnerability.
CVE Analysis
- CVE ID: CVE-2026-14804.
- Affected product/version: HUMANIST Digital Human Resources, versions from 26.0 before 26.1.
- Vulnerability class: CWE-321, use of hard-coded cryptographic key.
- Attack vector: Reading sensitive constants within an executable.
