AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Description states unauthenticated network-reachable SSTI yielding full RCE, so AV:N/AC:L/PR:N/UI:N with C:H/I:H/A:H; scope unchanged as impact stays on the vulnerable host.

5DescriptionCVE.org
In DocsGPT 0.15.0 and below, the application provides a custom prompt feature that allows users to define prompt content used during chatbot interactions. This functionality renders user-supplied prompt data using Jinja templates without input sanitization or sandboxing. An unauthenticated attacker can inject malicious template expressions, leading to a server-side template injection (SSTI) vulnerability that can be exploited to achieve full remote code execution (RCE).
AnalysisAI
Remote code execution in DocsGPT 0.15.0 and earlier arises from its custom-prompt feature, which passes user-supplied prompt content into Jinja template rendering with no sanitization or sandboxing. An unauthenticated attacker can submit crafted template expressions to achieve server-side template injection (SSTI) that escalates to full RCE on the host running the chatbot backend. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target DocsGPT instance (version <=0.15.0) expose the custom-prompt feature to the attacker and that user-supplied prompt content be rendered through the unsandboxed Jinja engine - this is the default behavior of the feature, and the CVSS vector (PR:N/UI:N) indicates no authentication or user interaction is needed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H = 9.8) is internally consistent with the description of an unauthenticated, network-reachable SSTI yielding full RCE, and SSVC rates technical impact as 'total' and automatable as 'yes' - both signals that align with high urgency. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released fixed version is identified in the supplied data, so upgrade first to any release later than 0.15.0 once Arc53 publishes one and monitor the DocsGPT GitHub repository and https://vuldb.com/vuln/399064 for a patch reference. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all systems running DocsGPT 0.15.0 or earlier and immediately restrict network access to internal-only, blocking all external connections to affected instances. …
