DescriptionCVE.org

A Stored Cross-Site Scripting (XSS) vulnerability exists in Frappe Framework version 17.0.0-dev due to improper neutralization of user-controlled input in the Number Card component.

AnalysisAI

Stored Cross-Site Scripting in Frappe Framework 17.0.0-dev allows a high-privileged authenticated user to inject persistent malicious scripts into the Number Card dashboard component, which then execute in the browsers of other users who view the affected dashboard. The CVSS 4.0 vector (PR:H/UI:A) confirms exploitation requires admin-level access to plant the payload and a victim's browser interaction to trigger it, limiting realistic blast radius despite the network delivery vector. …

Vulnerability AssessmentAI

Exploitation Exploitation requires a high-privilege authenticated session (PR:H per CVSS vector) with permission to create or edit Number Card components in the Frappe dashboard. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 score of 4.6 (Medium) accurately reflects a constrained attack surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with administrative access to a Frappe instance - whether a malicious insider or an external actor who has compromised an admin credential - navigates to the Number Card configuration interface and injects a JavaScript payload (e.g., a cookie-stealing script) into an unsanitized field. The payload is stored server-side and rendered each time any user loads a dashboard containing that card, silently exfiltrating session tokens or performing actions on the victim's behalf.
Remediation No vendor-released patch version has been identified in the available data. … Detailed patch versions, workarounds, and compensating controls in full report.
