Verified Facts
- CVE-2026-67207 is a high-severity vulnerability in Wolf CMS — NVD.
- The vulnerability affects Wolf CMS versions up to 0.8.3.1 — NVD.
- The CVSS score for this vulnerability is 8.8 — NVD.
Threat Classification
This threat is classified as an authorization bypass vulnerability, affecting the software sector, with a global geographic scope, and is considered (HIGH CONFIDENCE) to be exploitable. The motivation behind this vulnerability is likely to gain unauthorized access to sensitive data, with (MEDIUM CONFIDENCE) attribution to potential threat actors seeking to exploit software vulnerabilities for malicious purposes.
Threat Severity Assessment
- Exploitability: HIGH - due to the ease of exploitation by authenticated non-administrative users.
- Scope of impact: HIGH - as it allows access to restricted backup functionality, potentially leading to data breaches.
- Prevalence: MEDIUM - as it affects a specific software version, but the software may be widely used.
- CVSS score: 8.8, indicating a HIGH severity vulnerability.
Business Impact
This vulnerability poses a significant risk to organizations using Wolf CMS, as it could lead to operational disruption, regulatory liability under GDPR, NIS2, DORA, or SOC 2, with potential penalties, and reputational damage if sensitive data is accessed or breached. The financial exposure is estimated to be significant, depending on the scope of the breach and the organization's compliance with regulatory requirements.
Technical Analysis
The vulnerability is caused by a PHP operator precedence flaw in the permission check expression in the BackupRestoreController, allowing authenticated non-administrative users to access restricted backup functionality. The attack vector is through the BackupRestoreController, and the root cause is the incorrect evaluation of the access control expression.
CVE Analysis
- CVE ID: CVE-2026-67207
- Affected product/version: Wolf CMS up to 0.8.3.1
- Vulnerability class: Authorization bypass (CWE-697)
- Attack vector: Through the BackupRestoreController
- Authentication requirement: Authenticated non-administrative users
- Patch availability: A patch is required to mitigate this vulnerability
MITRE ATT&CK Mapping
- Tactic → T1068: Exploitation for Privilege Escalation — The vulnerability allows authenticated non-administrative users to access restricted backup functionality, potentially leading to privilege escalation.
IOC Intelligence
No public IOCs are confirmed at the time of publication. However, defenders should build hunt rules around the following behavioral indicators: - Unusual backup activity - Access to restricted backup functionality by non-administrative users - Anomalous PHP operator precedence errors - Unexpected changes to access control expressions
Detection Engineering Guidance
SIEM engineers should monitor logs for unusual backup activity, access to restricted backup functionality by non-administrative users, and anomalous PHP operator precedence errors. Detection logic should include telemetry fields such as user ID, access level, and backup activity, with a rationale based on the vulnerability's exploitability and potential impact.

Threat Hunting Queries
- Hypothesis: Unusual backup activity by non-administrative users — Log source: Web server logs, Data source: User ID, access level, and backup activity
- Hypothesis: Access to restricted backup functionality — Log source: Application logs, Data source: User ID, access level, and backup activity
- Hypothesis: Anomalous PHP operator precedence errors — Log source: Web server logs, Data source: Error messages and PHP operator precedence errors
- Hypothesis: Unexpected changes to access control expressions — Log source: Configuration logs, Data source: Access control expressions and configuration changes
- Hypothesis: Privilege escalation attempts — Log source: Security logs, Data source: User ID, access level, and privilege escalation attempts
SOC Analyst Playbook
- P0 (immediate): Verify the vulnerability and assess the potential impact on the organization — Tool: NVD, Log source: Web server logs
- P1 (urgent): Monitor logs for unusual backup activity and access to restricted backup functionality — Tool: SIEM, Log source: Web server logs
- P2 (same-day): Conduct a thorough analysis of the vulnerability and develop a mitigation plan — Tool: Vulnerability scanner, Log source: Configuration logs
Executive Decision Matrix
| Priority | Decision Required | Owner | Timeline |
|---|---|---|---|
| P0 | Patch approval | CISO | Immediate |
| P1 | Vulnerability assessment and mitigation plan development | Security Team | Urgent |
| P2 | Communication with stakeholders and regulatory bodies | Compliance Officer | Same-day |
Executive Recommendations
- Day 1-7: Immediately patch or mitigate the vulnerability, and monitor logs for unusual activity
- Day 8-30: Conduct a thorough analysis of the vulnerability, develop a mitigation plan, and implement additional security controls
- Day 31-90: Review and update incident response plans, conduct regular security audits, and provide training to personnel on vulnerability management and incident response
MSSP Opportunities
CYBERDUDEBIVASH SENTINEL APEX recommends that MSSPs prioritize client notification for organizations using Wolf CMS, deploy detection rules for unusual backup activity and access to restricted backup functionality, and activate threat hunting for potential exploitation of the vulnerability.
