Severity by source
AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
CORS abuse needs a victim's authenticated browser to visit an attacker page (UI:R); high data exposure (C:H) plus the described privileged actions imply limited integrity impact (I:L), no availability effect.
Primary rating from Vendor (HCL).

Lifecycle Timeline

HCL DevOps Deploy uses Cross-Origin Resource Sharing (CORS) which could allow an attacker to carry out privileged actions and retrieve sensitive information as the domain name is not being limited to only trusted domains.
AnalysisAI
Sensitive-information disclosure in HCL DevOps Deploy (formerly UrbanCode Deploy) versions 8.1 through 8.1.2.6 and 8.2 through 8.2.1.0 stems from an overly permissive Cross-Origin Resource Sharing (CORS) policy that fails to restrict allowed origins to trusted domains. Because the application accepts or reflects arbitrary origins, an attacker-controlled web page can issue cross-origin credentialed requests against an authenticated user's session to read protected data and invoke privileged actions. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that HCL DevOps Deploy is running the misconfigured CORS policy that does not limit Access-Control-Allow-Origin to trusted domains (versions 8.1-8.1.2.6 and 8.2-8.2.1.0), and - because this is a browser-mediated cross-origin attack - that a user with an active authenticated DevOps Deploy session is induced to load attacker-controlled JavaScript (e.g., visits a malicious or compromised page). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed and lean moderate, not urgent. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious web page and lures a DevOps Deploy user who currently holds an authenticated session into visiting it. JavaScript on that page issues credentialed cross-origin requests to the DevOps Deploy API; because the CORS policy trusts the attacker's origin, the browser lets the script read the responses, exfiltrating sensitive deployment data and potentially triggering privileged operations. … |
| Remediation | Apply the fix described in HCL's advisory KB0131695 (https://support.hcl-software.com/csm?id=kb_article&sysparm_article=KB0131695); patch available per vendor advisory, but an exact fixed build number is not stated in the available data, so confirm the target version with HCL and upgrade beyond 8.1.2.6 and 8.2.1.0. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Identify all HCL DevOps Deploy servers running versions 8.1-8.2.1.0; implement network-level access restrictions to trusted administrative networks only. …
