AnalysisAI
Information disclosure with integrity impact in the Spotfire Server modules of Spotfire Enterprise, Spotfire Enterprise with External Consumers, and Spotfire on Kubernetes allows a remote, unauthenticated attacker to obtain sensitive data and alter server-side state once a victim is lured into a passive interaction (UI:P), such as opening a crafted link or analysis. The CVSS 4.0 base score is 8.7 (High) with high confidentiality and integrity impact and low availability impact. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires no authentication (PR:N) and no elevated privileges, but is gated by passive user interaction (UI:P): a legitimate user must be induced to perform an action such as opening a crafted link or loading attacker-supplied content served through the network-reachable Spotfire Server web interface. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P) describes a network-reachable, low-complexity, unauthenticated flaw whose only meaningful barrier is required passive user interaction (UI:P), yielding a High 8.7 score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious link or analysis payload targeting an internet-facing Spotfire Server and delivers it to a legitimate user via email or a web page. When the victim opens it (the passive UI:P interaction), the server processes attacker-influenced content that leaks sensitive data and allows the attacker to tamper with server-side state. … |
| Remediation | Patch available per vendor advisory: consult the Spotfire Security Advisory of July 14, 2026 (https://community.spotfire.com/articles/spotfire/spotfire-security-advisory-july-14-2026-spotfire-cve-2026-8590-r3641/) and upgrade each product past its listed affected ceiling - Spotfire Enterprise and External Consumers builds beyond the 14.8.0 branch, and Spotfire on Kubernetes beyond the 4.2.0/5.0.X/6.0.X lines; exact fixed-version numbers are not provided in this dataset and must be confirmed from that advisory. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
