CVE-2025-33116
📋 TL;DR
IBM Watson Studio 4.0 through 5.2.0 on Cloud Pak for Data contains a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious JavaScript into the web interface. This could enable attackers to steal session credentials or manipulate user interactions within trusted sessions. Only authenticated users can exploit this vulnerability.
💻 Affected Systems
- IBM Watson Studio on Cloud Pak for Data
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal administrator credentials, hijack user sessions, perform actions on behalf of authenticated users, or redirect users to malicious sites.
Likely Case
An authenticated malicious insider or compromised account could steal session tokens or credentials from other users, potentially escalating privileges within the Watson Studio environment.
If Mitigated
With proper input validation and output encoding implemented, the attack surface is minimized, though the vulnerability still exists in unpatched systems.
🎯 Exploit Status
Exploitation requires authenticated access and knowledge of how to inject JavaScript into vulnerable UI components. No public exploit code is currently available.
