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 Desk desktop icon renderer.
AnalysisAI
Stored Cross-Site Scripting in Frappe Framework 17.0.0-dev allows an authenticated low-privileged user to inject persistent malicious scripts via the Desk desktop icon renderer, which then execute in the browsers of other users - including administrators - who subsequently view the affected Desk interface. The vulnerability was reported by Fluid Attacks and carries a CVSS 4.0 score of 4.8 (Medium), reflecting cross-user impact limited to the subsequent-system scope (SC:L/SI:L). …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker to hold a valid authenticated session on the Frappe instance with at least low-level privileges sufficient to create or modify Desk desktop icons (PR:L per CVSS). … 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:L/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N) scores 4.8 Medium, reflecting several limiting factors: low privileges are required to plant the payload (PR:L), a victim must actively interact with the Desk to trigger it (UI:A), and the direct impact on the vulnerable system itself is nil (VC/VI/VA all N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated low-privileged Frappe Desk user crafts a stored XSS payload embedded in a custom desktop icon name or related field and saves it to the application. When an administrator or another user subsequently opens their Desk view, the injected script executes silently in their browser, potentially stealing session cookies, exfiltrating CSRF tokens, or performing actions under the victim's identity. … |
| Remediation | Upstream fix availability has not been confirmed - no patched release version is cited in the available data, and the GitHub reference (https://github.com/frappe/frappe) does not point to a specific commit or tagged release resolving this issue. … Detailed patch versions, workarounds, and compensating controls in full report. |
