CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2026-38361 is a high-severity Uncontrolled Resource Consumption (CWE-400) vulnerability in Fohrloop Dash-Uploader. Its CVSS base score is 7.5 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique OS Exhaustion Flood (T1499.001); ranked in the top 16% of CVEs by exploit likelihood; 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 SA-11 (Developer Testing and Evaluation) and SC-5 (Denial-of-service Protection) — see the control section below for these in your framework.

Vulnerability Data
Multiple unauthenticated denial-of-service (DoS) issues in fohrloop dash-uploader v0.1.0 through v0.7.0a2. The chunked-upload handler (dash_uploader/httprequesthandler.py, dash_uploader/upload.py) trusts unsanitized, attacker-controlled upload parameters (e.g. flowTotalChunks) and does not enforce the documented max_file_size limit, allowing a remote, unauthenticated attacker to cause an out-of-memory…
more
(OOM) process crash (unbounded range(1, flowTotalChunks + 1) allocation), truncation of the target file to zero bytes (flowTotalChunks=0, where the all([]) == True quirk runs the file-assembly branch on zero chunks), permanent disk exhaustion (never-cleaned-up temporary directories per flowIdentifier), and a complete bypass of the documented max_file_size limit.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation at post-design stages directly exercises control-flow paths and reveals mismatches between implemented and intended behavior.
SC-5 directly limits the effects of resource-exhaustion events that constitute uncontrolled consumption.
SC-6 enforces explicit allocation limits on resources, structurally preventing the weakness from occurring.
Requiring a documented development process and supporting tools reduces the chance that incorrect control-flow logic is introduced in the first place.
Process isolation confines resource consumption to separate domains, reducing blast radius without stopping the root flaw.
Flaw identification and remediation processes can locate and correct control-flow errors once they manifest as incorrect runtime behavior.

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.
Explicitly requires monitoring and maintaining resource capacity, directly addressing uncontrolled consumption to preserve availability.
Secure SDLC practices directly prevent incorrect control-flow implementations via reviews, testing, and static analysis.
Continuous monitoring of computing resources can detect resource exhaustion but does not itself enforce allocation limits.
Resilience mechanisms such as avoiding single points of failure indirectly reduce impact of resource exhaustion.
Hardened configuration baselines can include resource quotas and limits that constrain consumption.

Resource-utilization monitoring and alerting on bottlenecks or overloads limits the impact of denial-of-service or resource-exhaustion attacks.
Security testing in development and acceptance can detect paths that deviate from intended logic.
By continuously monitoring utilization, stress-testing peak loads, and maintaining documented plans to scale or throttle resources, the control directly limits an attacker’s ability to drive a system into uncontrolled resource exhaustion.
Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.
Business-continuity plans that include resource-management controls reduce the likelihood that an attacker can trigger uncontrolled resource consumption by forcing the system into a degraded or fallback state.
Defining RTOs and capacity requirements for ICT services during business-impact analysis forces organizations to provision sufficient resources and throttling mechanisms, reducing the likelihood that an attacker can induce denial-of-service through uncontrolled resource consumption.
