CVE-2025-0719 Overview
CVE-2025-0719 is a reflected cross-site scripting (XSS) vulnerability affecting IBM Cloud Pak for Data versions 4.0.0 through 4.8.5 and 5.0.0. The flaw allows an unauthenticated attacker to embed arbitrary JavaScript in the Web UI. Successful exploitation requires user interaction, such as clicking a crafted link, and executes attacker-supplied script within the victim's trusted session context. The issue is tracked under CWE-79 and can lead to credential disclosure and session manipulation within the IBM Cloud Pak for Data administrative interface.
Critical Impact
An unauthenticated attacker can inject JavaScript into the Web UI, altering intended functionality and potentially disclosing credentials within a trusted session.
Affected Products
- IBM Cloud Pak for Data 4.0.0 through 4.8.5
- IBM Cloud Pak for Data 5.0.0
- Deployments exposing the Web UI to untrusted networks

Technical Details for CVE-2025-0719
Vulnerability Analysis
CVE-2025-0719 is a stored or reflected cross-site scripting weakness in the IBM Cloud Pak for Data Web UI. The application fails to properly neutralize user-supplied input before rendering it in the browser. Attacker-controlled JavaScript executes within the origin of the Cloud Pak for Data console. Because the script runs in a trusted session context, it can access session tokens, DOM content, and issue authenticated API requests on behalf of the victim. The vulnerability requires user interaction, meaning a target must load an attacker-crafted URL or interact with a poisoned interface element. The scope change component indicates the injected script influences resources beyond the vulnerable component's security boundary, which is characteristic of browser-executed payloads that pivot into authenticated sessions.
Root Cause
The root cause is improper neutralization of input during web page generation, classified as [CWE-79]. IBM Cloud Pak for Data does not sufficiently encode or sanitize input reflected into the Web UI. Attacker-supplied HTML or script fragments reach the DOM without being escaped, allowing arbitrary JavaScript to run in the victim's browser.
Attack Vector
Exploitation proceeds over the network without authentication. An attacker crafts a malicious URL or payload targeting a vulnerable Web UI endpoint. The attacker then delivers the link via phishing, chat, or a compromised web page. When an authenticated Cloud Pak for Data user loads the payload, the browser executes the injected JavaScript. The script can exfiltrate session cookies, harvest credentials via fake login prompts, or invoke platform APIs with the victim's privileges.
No verified proof-of-concept code has been published. See the IBM Support Document for vendor technical details.
Detection Methods for CVE-2025-0719
Indicators of Compromise
- Web server access logs containing URL parameters with <script>, javascript:, onerror=, or encoded variants targeting Cloud Pak for Data endpoints
- Unexpected outbound HTTP requests from user browsers to attacker-controlled domains following Web UI access
- Session activity from user accounts originating from anomalous IP addresses shortly after a user clicked an external link
Detection Strategies
- Deploy web application firewall (WAF) rules that inspect query strings and POST bodies for XSS payload patterns targeting the Cloud Pak for Data Web UI
- Correlate proxy and email gateway telemetry to identify inbound links pointing at Cloud Pak for Data hosts with suspicious parameters
- Review browser console errors and Content Security Policy (CSP) violation reports from user endpoints accessing the console
Monitoring Recommendations
- Enable verbose HTTP access logging on Cloud Pak for Data ingress controllers and forward logs to a centralized analytics platform
- Monitor authentication events for session reuse from multiple geographies, which may indicate stolen session tokens
- Alert on Cloud Pak for Data API calls that deviate from a user's baseline behavior after Web UI interaction
How to Mitigate CVE-2025-0719
Immediate Actions Required
- Apply the fix described in the IBM Support Document to all affected Cloud Pak for Data 4.x and 5.0.0 deployments
- Restrict Web UI network exposure to trusted management networks or VPN-protected access
- Instruct administrators to avoid clicking Cloud Pak for Data links received from untrusted sources until patching is complete
Patch Information
IBM has published remediation guidance in the vendor advisory at IBM Support Document 7184173. Administrators running versions 4.0.0 through 4.8.5 or 5.0.0 should upgrade to the fixed release identified by IBM. Verify the upgrade by confirming the platform build version after applying the patch bundle.
Workarounds
- Enforce a strict Content Security Policy on the Cloud Pak for Data Web UI reverse proxy to block inline script execution
- Configure browser session cookies with HttpOnly and SameSite=Strict attributes at the ingress layer to reduce token theft risk
- Rotate administrative credentials and invalidate active sessions after patching to eliminate any tokens captured prior to remediation
