A Server-Side Template Injection (SSTI) vulnerability in WGDashboard version 4.3.2 and earlier, allows authenticated attackers to execute arbitrary code as root.
AnalysisAI
Remote code execution in WGDashboard 4.3.2 and earlier lets authenticated attackers inject Server-Side Template Injection payloads that execute arbitrary commands as root, giving full host compromise. Publicly available exploit code exists (Stuub's SSTI-to-Root-RCE PoC), though the flaw is not listed in CISA KEV and carries a low EPSS score of 0.28% (20th percentile), indicating no evidence of widespread automated exploitation yet. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated session to the WGDashboard web interface - the description explicitly states 'authenticated attackers,' which contradicts the supplied CVSS PR:N and is the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are partially conflicting and warrant nuance. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained valid WGDashboard credentials (via reuse, phishing, weak default passwords, or a low-privilege user account) submits a crafted value into a dashboard field that is rendered server-side by the template engine, embedding a Jinja2-style payload that escapes into Python and invokes an OS command. Because the service runs as root, the payload executes with root privileges, yielding full host takeover. … |
| Remediation | No specific fixed version was included in the provided intelligence, so treat the fix status as 'No vendor-released patch version identified at time of analysis' and monitor the upstream repository (https://github.com/WGDashboard/WGDashboard) and the NVD entry (https://nvd.nist.gov/vuln/detail/CVE-2026-15734) for a tagged release above 4.3.2, then upgrade immediately once published. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all WGDashboard instances running version 4.3.2 or earlier, prioritizing those exposed to the internet; immediately restrict network access to trusted internal networks only using firewall rules, or take systems offline if operationally feasible. …
