Exploitation Conditions

The CVSS vector (AV:N/AC:L/PR:N/UI:N) and the explicit statement that exploitation does not require user interaction indicate no special conditions - remote unauthenticated exploitation against network-reachable deployments of Adobe ColdFusion (2023 ≤2023.0.25 and 2025 ≤2025.0.13). The scope change (S:C) means impact reaches internal systems beyond the ColdFusion process boundary, so the practical severity depends on what internal services the server can reach (e.g., cloud metadata endpoints, internal APIs); segmentation and egress filtering that restrict the server's outbound/internal reachability are the primary limiting factors. The description does not name a specific feature or non-default setting that must be enabled, so exploitation appears to apply to standard configurations of the affected versions; limiting factors are therefore version (patched builds above the listed ranges are not affected) and network exposure rather than configuration or authentication.

Impact

This is a credible priority flaw, though several real-risk signals are missing from the provided data. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N, base 8.6) describes a network-reachable, low-complexity, unauthenticated SSRF with a changed scope and high confidentiality impact - the classic high-severity profile for an internet-facing application server. No EPSS score, no CISA KEV listing, and no POC indicator were supplied, so exploitation probability and in-the-wild activity cannot be quantified from this input: no public exploit identified at time of analysis. No SSVC decision data was provided either. The key tension to flag: the description frames the outcome as 'privilege escalation,' yet the CVSS vector assigns C:H with I:N and A:N, which is consistent with SSRF-driven information disclosure (e.g., reading internal metadata or credentials) rather than direct rights modification - verify with Adobe APSB26-144 whether 'privilege escalation' is a downstream consequence of the SSRF rather than a separate integrity impact. Context weighs toward elevated attention: Adobe ColdFusion has a strong history of rapid exploitation of unauthenticated server-side bugs, so the absence of a KEV entry likely reflects timing/recency rather than low threat. Confirmed signals (vendor-sourced CVSS, affected versions, patch) justify prompt patching; unconfirmed signals (EPSS/KEV/POC) mean the 'active exploitation' question remains open and should be monitored.

Exploit ScenarioDerived

A remote, unauthenticated attacker sends a crafted request to an internet-facing ColdFusion server, coercing it to issue server-side requests to internal-only endpoints (such as cloud instance metadata services or internal APIs) and harvesting sensitive responses that enable privilege escalation. Because the CVSS vector is AV:N/AC:L/PR:N/UI:N with scope changed, no credentials or user interaction are needed and the impact crosses into otherwise-unreachable internal systems. No public exploit identified at time of analysis, so this scenario is inferred from the SSRF (CWE-918) classification and CVSS metrics.

AnalysisAIv1 – Oct 13, 2026

Server-side request forgery in Adobe ColdFusion lets remote unauthenticated attackers force the server to issue requests to internal or otherwise protected endpoints, which Adobe flags as potentially escalating privileges across a security boundary. The affected builds are ColdFusion 2023 up to and including 2023.0.25 and ColdFusion 2025 up to and including 2025.0.13; the CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N, base 8.6) confirms no user interaction and no authentication prerequisite, with confidentiality being the only impact dimension assessed. No public exploit code has been identified at time of analysis and the flaw is not in CISA KEV, so risk derives from high internet/network exposure of affected builds rather than confirmed active exploitation. Real-world severity hinges on what the ColdFusion host can reach internally, since a scope-changed SSRF that touches cloud metadata services or internal admin APIs can yield credential material even without an integrity or availability impact.

RemediationAI

Apply the vendor hotfix described in Adobe advisory APSB26-144 (https://www.adobe.com/trust/security/products/coldfusion/apsb26-144.html) and move each instance above the affected ranges, i.e., beyond 2023.0.25 on the 2023 track and beyond 2025.0.13 on the 2025 track - patch availability is per the vendor advisory, and exact build numbers should be confirmed against the advisory itself since the input data does not enumerate them. Where patching cannot be completed immediately, the highest-value compensating control is outbound egress restriction from the ColdFusion host: block the server from reaching cloud metadata endpoints such as 169.254.169.254 and other link-local ranges, and deny access to internal management networks and services the application does not legitimately consume; the trade-off is that legitimate integrations and internal API calls may break, so tight allow-lists should be built from observed traffic first. Network segmentation (placing ColdFusion in a DMZ-like segment with no lateral reachability) and blocking public exposure of the ColdFusion Administrator reduce the practical impact of a scope-changed SSRF but do not fix the underlying flaw and can disrupt internal application dependencies that rely on those routes. Restricting access to the Administrator interface and monitoring for anomalous server-side requests to internal addresses provide detection value but are not substitutes for the patch. Finally, consider rotating credentials and tokens that were reachable from the ColdFusion host, since SSRF-driven privilege escalation typically depends on material the server could already read.

Technical ContextAI · show details

The root cause class is CWE-918 (Server-Side Request Forgery): Adobe ColdFusion, a Java-based application server for enterprise web applications, can be induced to make an outbound request to an attacker-influenced destination, with the request originating from the ColdFusion process rather than from the attacker's own client. The CVSS vector's scope change (S:C) indicates the exploited component's impact extends beyond its own security authority, consistent with a redirect or request relay reaching internal services that the attacker could not otherwise address directly. The impact triad C:H/I:N/A:N describes a high-confidentiality, read-only outcome in the assessed scenario - typical when SSRF is used to retrieve cloud instance metadata, internal configuration endpoints, or administrative APIs and harvest credentials or tokens, which is the mechanism behind the reported privilege-escalation potential. Because the CVSS vector carries PR:N and UI:N alongside the vendor statement that no user interaction is required, the standard deployment posture of an affected ColdFusion instance is sufficient; no named feature or non-default setting has been identified as a precondition, so version range and network reachability are the limiting factors rather than configuration or credentials.

Executive ViewAI

Why It Matters

Adobe ColdFusion servers running builds up to and including 2023.0.25 or 2025.0.13 carry an unauthenticated server-side request forgery flaw that allows an outside party to direct the server to reach internal endpoints, and no vendor fix has been released yet. Practically, a public-facing ColdFusion host can be used to reach cloud metadata services, internal admin consoles, and service APIs that are otherwise shielded from the internet, potentially exposing credentials and configuration secrets that enable wider access to our environment. No public exploit code has been identified at time of analysis, so the immediate risk is driven by how many affected builds we expose and what those hosts can reach internally, rather than by confirmed attacks.

Business Impact: High
Compensating Controls

No vendor-released patch identified at time of analysis. Interim mitigations: remove affected ColdFusion builds (2023.0.25 and earlier, 2025.0.13 and earlier) from direct internet exposure via authenticated reverse proxy, VPN, or allow-listed source IPs; enforce strict outbound egress filtering so ColdFusion hosts cannot reach cloud metadata endpoints (169.254.169.254), internal admin interfaces, or unneeded internal subnets; enforce IMDSv2 or disable instance metadata on cloud hosts; run the service with least privilege and isolate it on a segmented network; rotate credentials, API keys, and secrets reachable from the host; enable and monitor outbound request and error logging for signs of SSRF probing.
