Stored XSS requires low-priv account (PR:L) to plant payload and victim interaction to trigger (UI:R); scope change applies as attacker JS runs in victim browser context.

Stored Cross-Site Scripting (XSS) in TaskRunHandler.post() in web/handlers/task.py in QD 20220208 through 20250803. When a task is run via /task/<taskid>/run, the handler renders task log content (logtmp) into the HTML response using Python % string formatting without HTML encoding. logtmp is populated from the exception object or from new_env.variables.__log__, which is attacker-controlled via the template extract_variables mechanism. A low-privileged authenticated attacker can create a crafted HAR template that extracts arbitrary HTML/JavaScript into the __log__ variable via the api://util/unicode endpoint. When a victim triggers the task run, the embedded script executes in the victim browser within the QD application context.
AnalysisAI
Stored XSS in QD (versions 20220208-20250803) allows a low-privileged authenticated attacker to inject arbitrary JavaScript into the task execution log output, which then executes in a victim user's browser when they trigger the affected task run. The injection path runs through HAR template variables - specifically the __log__ field populated via the extract_variables mechanism and the api://util/unicode endpoint - which are rendered unsanitized into HTML via Python % string formatting in TaskRunHandler.post(). …

Vulnerability AssessmentAI
| Exploitation | Attacker must hold a low-privileged authenticated account within the QD application (CVSS PR:L confirmed) with permission to create or modify HAR templates. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The provided CVSS 5.4 Medium (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N) accurately captures the core risk profile: network-reachable, low complexity, but gated behind PR:L (requires a QD account) and UI:R (victim must trigger the task run). … 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 confirmed patched release version is identified from the available input data. … Detailed patch versions, workarounds, and compensating controls in full report. |
