Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N
Network-reachable XSS with low complexity and no auth but requiring victim interaction (UI:R); impact is browser-context-bounded so C:L/I:L, with S:C reflecting cross-context script execution.
Primary rating from Vendor (ibm).

IBM Engineering AI Hub 1.0.0, 1.1.0, and 1.2.0 could allow a remote attacker to execute arbitrary scripts due to improper neutralization of input during web page generation.
AnalysisAI
Stored/reflected cross-site scripting in IBM Engineering AI Hub 1.0.0 through 1.2.0 lets a remote unauthenticated attacker inject arbitrary scripts into generated web pages that execute in a victim's authenticated browser session. Because the CVSS scope is marked changed (S:C), successful exploitation can impact resources beyond the vulnerable component - such as the user's session with adjacent applications. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim with access to IBM Engineering AI Hub (versions 1.0.0-1.2.0) interact with attacker-controlled content - this is the UI:R limiting factor: the attacker cannot fire the payload autonomously and must get a user to load a crafted request, link, or page where unsanitized input is rendered. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The vendor CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N, 9.3) rates this Critical, driven largely by C:H/I:H combined with the changed scope - an aggressive impact rating for XSS, which typically confers Low confidentiality/integrity impact bounded by the victim's browser context; verify the High impact rating against IBM's advisory before treating it as full-session compromise. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious URL or input that embeds a JavaScript payload and delivers it to a legitimate Engineering AI Hub user (e.g. via a phishing link or a shared engineering artifact). … |
| Remediation | Apply the vendor-provided fix: Patch available per vendor advisory (IBM Support document https://www.ibm.com/support/pages/node/7279964) - consult that advisory for the exact fixed release, as no specific patched version string was supplied in the input and version numbers should not be invented. … Detailed patch versions, workarounds, and compensating controls in full report. |
