CVE-2026-106622 Overview
Adobe ColdFusion contains a Server-Side Request Forgery (SSRF) vulnerability that enables privilege escalation. The flaw is tracked under CWE-918 and is addressed in Adobe Security Advisory APSB26-144. Attackers can exploit the issue over the network without authentication or user interaction. The vulnerability has a changed scope, meaning exploitation impacts resources beyond the vulnerable component itself.
Critical Impact
Unauthenticated remote attackers can coerce ColdFusion into issuing attacker-controlled requests, pivot into internal services, and escalate privileges across trust boundaries.

Technical Details for CVE-2026-106622
Vulnerability Analysis
The vulnerability is a Server-Side Request Forgery flaw in Adobe ColdFusion. An unauthenticated attacker sends a crafted request that causes the ColdFusion server to initiate outbound requests to attacker-chosen destinations. Because scope changes during exploitation, the request executes in a security context different from the component that received the input.
The net effect is privilege escalation. SSRF typically allows attackers to reach cloud metadata endpoints, internal management interfaces, and services bound to loopback addresses. On ColdFusion, those pivots can expose administrator interfaces and credential material usable for further compromise.
Full impact to confidentiality, integrity, and availability is achievable from a single network request. No prior authentication, user action, or local access is required.
Root Cause
The root cause is improper validation of a user-supplied URL or host parameter that ColdFusion subsequently requests server-side. Classified as CWE-918: Server-Side Request Forgery, the server trusts input that identifies a remote resource and does not restrict the destination to an allow list of safe targets.
Attack Vector
The attack vector is network-based and does not require authentication or user interaction. An attacker submits a request containing a URL or host that points to an internal resource, a cloud instance metadata service, or an administrative endpoint. ColdFusion issues the request on behalf of the attacker, and the response or side effects grant elevated access. Public exploit code is not currently listed in CISA KEV or ExploitDB, and no proof-of-concept URLs are published in the NVD record. Refer to Adobe Security Advisory APSB26-144 for vendor technical detail.
Detection Methods for CVE-2026-106622
Indicators of Compromise
- Outbound HTTP or HTTPS requests from the ColdFusion JVM process to internal RFC1918 addresses, 127.0.0.1, or cloud metadata endpoints such as 169.254.169.254.
- Unexpected ColdFusion access log entries containing URL parameters that reference internal hostnames, loopback addresses, or file://, gopher://, and dict:// schemes.
- New or anomalous administrative sessions on the ColdFusion Administrator shortly after inbound requests from untrusted sources.
Detection Strategies
- Inspect web and reverse-proxy logs for parameters carrying URL values and correlate them with outbound connections initiated by the ColdFusion service account.
- Alert on any ColdFusion-originated request to cloud metadata IP ranges or to management ports on internal infrastructure.
- Baseline normal outbound destinations for the ColdFusion host and flag deviations.
Monitoring Recommendations
- Enable verbose request logging on the ColdFusion server and forward logs to a centralized analytics platform for correlation.
- Monitor egress firewall telemetry for connections from ColdFusion to internal subnets that it does not normally contact.
- Track authentication events and privilege changes on systems that trust the ColdFusion host network segment.
How to Mitigate CVE-2026-106622
Immediate Actions Required
- Apply the ColdFusion security update referenced in Adobe Security Advisory APSB26-144 on all affected hosts.
- Restrict egress from ColdFusion servers to only the destinations required for business operations.
- Block ColdFusion access to cloud instance metadata services, or require IMDSv2 with hop-limit enforcement on AWS workloads.
- Audit ColdFusion Administrator accounts and rotate credentials that may have been exposed through SSRF-reachable services.
Patch Information
Adobe published fixed ColdFusion builds in Security Advisory APSB26-144. Review the advisory for exact affected versions, patched builds, and installation guidance. Prioritize internet-facing ColdFusion instances first.
Workarounds
- Place ColdFusion behind a web application firewall configured to block requests containing URL parameters pointing to internal address space or metadata endpoints.
- Deploy an egress proxy that enforces an allow list of permitted outbound destinations for the ColdFusion service account.
- Isolate ColdFusion servers in a network segment that cannot reach internal management interfaces or sensitive internal APIs.
