Severity by source
AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H
Network reflected XSS requiring the victim to open a malicious file (UI:R) with scope change to the browser session; realistic impact is limited script execution (C:L/I:L, A:N), not the vendor's H/H/H.

Lifecycle Timeline
6DescriptionNVD
ColdFusion is affected by a reflected Cross-Site Scripting (XSS) vulnerability. An attacker could exploit this vulnerability to inject malicious scripts into a web page, potentially gaining elevated access or control over the victim's account or session. Exploitation of this issue requires user interaction in that a victim must open a malicious file. Scope is changed.
AnalysisAI
Reflected Cross-Site Scripting (CWE-79) in Adobe ColdFusion 2023 (through Update 21) and ColdFusion 2025 (through Update 10) lets an unauthenticated attacker inject script into a rendered page when a victim opens a malicious file, executing in the victim's session with a scope change to the browser context. Adobe (psirt@adobe.com) rates it Critical (CVSS 9.6, S:C, C:H/I:H/A:H), though these impact metrics appear inflated for a reflected XSS. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires user interaction: a victim must open an attacker-crafted malicious file or link that reaches a ColdFusion endpoint reflecting unsanitized input (UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a URL or file targeting a reflected ColdFusion endpoint with an embedded XSS payload and delivers it to a logged-in ColdFusion user via phishing. When the victim opens the malicious file/link, the payload reflects into the response and executes in their browser, letting the attacker steal the session token or perform actions as the victim. … |
| Remediation | Apply the Adobe-released updates: upgrade Adobe ColdFusion 2023 to Update 22 and Adobe ColdFusion 2025 to Update 11 per Adobe advisory APSB26-82 (https://helpx.adobe.com/security/products/coldfusion/apsb26-82.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify and inventory all Adobe ColdFusion 2023 (Update 21 or earlier) and ColdFusion 2025 (Update 10 or earlier) instances connected to the internet or processing sensitive data, noting their criticality and external visibility. …
