Lifecycle Timeline
1DescriptionCVE.org
A Stored Cross-Site Scripting (XSS) vulnerability exists in Frappe Framework version 17.0.0-dev due to unsafe evaluation of user-controlled data in the Number Card component.
AnalysisAI
Stored XSS in Frappe Framework version 17.0.0-dev allows a high-privileged authenticated user to inject malicious JavaScript through the Number Card dashboard component, which subsequently executes in other authenticated users' browser sessions when they view affected dashboards. The CVSS 4.0 score of 4.6 (Medium) reflects the dual constraint of requiring high-privilege credentials to plant the payload and active victim interaction to trigger it - both of which meaningfully limit real-world exploitability. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires the attacker to already hold high-privilege credentials on the target Frappe Framework instance - specifically, privileges sufficient to create or modify Number Card components, which corresponds to an administrator or equivalent manager role (PR:H per CVSS 4.0 vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:H/UI:A) reflects a medium-severity finding constrained by two concrete factors: the attacker must already hold high-privilege credentials (PR:H) sufficient to create or modify Number Cards, and a separate victim must actively navigate to a dashboard containing the malicious card (UI:A). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with administrator or manager-level Frappe credentials creates a Number Card containing a JavaScript payload - for example, a fetch-based cookie exfiltration script targeting a remote attacker-controlled endpoint - and saves it to a dashboard shared with lower-privileged users. When a target user opens that dashboard, the stored payload silently executes in their browser, exfiltrating their session cookie or performing authenticated actions on their behalf. … |
| Remediation | No vendor-released patch version has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
