Unauthenticated network endpoint (PR:N/AV:N/AC:L); SSRF primarily discloses internal data and metadata credentials (C:H), with limited integrity from forced internal requests (I:L) and no availability impact.

Server-side request forgery (SSRF) in the /har/test endpoint in QD 20220208 through 20250803. Fetcher.build_request() in libs/fetcher.py constructs an httpclient.HTTPRequest from user-supplied JSON without validating URL scheme, host, or IP range. The /har/test handler does not require authentication, enabling unauthenticated remote attackers to force the QD server to send arbitrary HTTP requests to internal network resources and cloud metadata endpoints. validate_cert is set to False, disabling TLS verification.
AnalysisAI
Server-side request forgery in QD (qd-today), an open-source HTTP timed-task/check-in framework, lets remote unauthenticated attackers coerce the server into issuing arbitrary HTTP(S) requests. The unauthenticated /har/test endpoint passes user-supplied JSON into Fetcher.build_request() (libs/fetcher.py), which builds a Tornado HTTPRequest with no validation of URL scheme, host, or IP range and with TLS verification disabled (validate_cert=False), so an attacker can reach internal services and cloud metadata endpoints. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires network reachability to the QD server's /har/test endpoint, which by design requires no authentication, so on an internet-exposed instance there are effectively no additional prerequisites. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The signals are largely aligned toward high priority: the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N) describes a network-reachable, low-complexity, unauthenticated attack, and the description independently confirms the /har/test handler requires no authentication, so the network/unauthenticated claim is corroborated by two sources rather than inferred from CVSS alone. … 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 patched version is identified in the provided data, so the fix version cannot be cited; monitor the project at https://qd-today.github.io/qd/ and its GitHub repository for a release addressing the SSRF. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
