CVE-2025-36321: Vulnerabilities found in Watson Data Intelligence
IBM watsonx.data intelligence 5.2.0, 5.2.1, 5.2.2, 5.3.0 is vulnerable to HTML injection. A remote attacker could inject malicious HTML code, which when viewed, would be executed in the victim's Web browser within the security context of the hosting site.
Security readout for executives and security teams
Plain-English summary
IBM watsonx.data intelligence versions 5.2.0, 5.2.1, 5.2.2, and 5.3.0 are affected. A low-privileged remote attacker could inject malicious HTML that runs when a victim views it in the application. The main business risk is loss of browser-visible sensitive data.
Executive priority
Treat as a moderate-priority remediation for affected IBM watsonx.data intelligence environments, especially where sensitive data is viewed in-browser or lower-privileged users can create content seen by administrators.
Technical view
CVE-2025-36321 is a CWE-80 HTML injection issue in IBM watsonx.data intelligence. CVSS 3.1 is 5.7 with network access, low attack complexity, low privileges required, user interaction required, unchanged scope, high confidentiality impact, and no integrity or availability impact listed.
Likely exposure
Exposure is limited to organizations running the named IBM watsonx.data intelligence versions. Risk depends on whether untrusted or lower-privileged users can submit content that higher-value users later view.
Exploitation context
The provided sources do not show known active exploitation, and the CVE is not listed as KEV in the bundle. Exploitation requires victim viewing behavior and attacker privileges, so phishing-like workflow abuse is more likely than unauthenticated mass exploitation.
Researcher notes
The bundle identifies the vulnerability class, affected versions, CVSS vector, and IBM advisory, but does not include detailed root cause, exact vulnerable fields, fixed version numbers, or exploit telemetry. Avoid assuming script execution mechanics beyond the stated HTML injection behavior.
Mitigation direction
Check IBM advisory 7277801 for the supported remediation path.
Prioritize upgrading or patching affected watsonx.data intelligence deployments.
Restrict access to affected interfaces until remediation is complete.
Review user roles that can submit rendered HTML content.
Increase monitoring for suspicious content submissions or unusual user-session activity.
Validation and detection
Inventory watsonx.data intelligence deployments and record exact versions.
Confirm whether any deployment runs 5.2.0, 5.2.1, 5.2.2, or 5.3.0.
Verify the IBM advisory remediation has been applied.
Review application logs for suspicious rendered-content submissions.
In a safe test environment, confirm untrusted HTML is encoded or blocked.

CWE-80: User-session and phishing behavior lookup
Client-side and session-facing weaknesses should be reviewed alongside initial-access and user-execution behaviors. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS)
Improper Neutralization of Script-Related HTML Tags in a Web Page (Basic XSS) represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
