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 File View breadcrumb renderer.
AnalysisAI
Stored XSS in Frappe Framework 17.0.0-dev allows a high-privileged attacker to inject persistent malicious scripts into the File View breadcrumb renderer, which then execute in the browsers of other users who navigate to the affected view. The CVSS 4.0 vector (PR:H, UI:A, SC:L/SI:L) confirms that while network delivery is possible, exploitation is constrained by the need for elevated access to inject the payload and victim interaction to trigger it, with impact limited to the subsequent system (victim browser). …

Vulnerability AssessmentAI
| Exploitation | The attacker must possess a high-privilege account within the Frappe Framework instance (PR:H per CVSS 4.0 vector) sufficient to upload files or create folder structures whose names are reflected in the File View breadcrumb. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 4.6 (Medium) accurately reflects the constrained exploitation path. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with high-privilege access to a Frappe instance - such as a compromised admin account or a malicious insider - uploads a file or creates a folder whose name contains a crafted XSS payload (e.g., an injected script tag). When a lower-privileged user subsequently navigates to the File View and the breadcrumb renderer displays the file path without sanitization, the payload executes in the victim's browser session, potentially enabling session token theft or unauthorized actions on behalf of the victim. … |
| Remediation | No vendor-released patch with an exact fix version has been identified in the available data. … Detailed patch versions, workarounds, and compensating controls in full report. |
