Exploitation Conditions

Requires an authenticated low-privileged account on the ColdFusion server (PR:L) and affects ColdFusion 2023 (≤2023.0.25) and ColdFusion 2025 (≤2025.0.13). The vendor states exploitation 'depends on conditions beyond the attacker's control' (reflected as AC:H), meaning success is not deterministic and likely hinges on race timing, specific internal-network reachability, or environmental state rather than a single reliable request. No user interaction is required (UI:N). Limiting factors that reduce realistic risk: the required authenticated foothold, the high attack complexity, and impact that is primarily disclosure of internal resources (C:H) with only limited integrity impact (I:L) and no availability impact.

Impact

This is a moderate-severity SSRF (CWE-918) in Adobe ColdFusion with a vendor-assigned CVSS 7.1 (CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N). The signals are internally consistent but point to a conditional, not drive-by, threat: the network vector (AV:N) and no-user-interaction requirement are offset by high attack complexity (AC:H) and a required low-privilege account (PR:L), and the description explicitly states 'Exploit depends on conditions beyond the attacker's control,' which corroborates AC:H. The changed scope (S:C) with C:H reflects the SSRF reaching internal resources outside the initially vulnerable component, which drives the score up. No EPSS score, CISA KEV listing, SSVC decision, or public POC was provided in the input, so there is no evidence of active exploitation or weaponization and the probability of mass exploitation cannot be quantified from the data given. On balance this is a real but mid-tier priority: it is not a remote-unauthenticated RCE, it requires an existing authenticated foothold plus favorable conditions, and it should be patched on a normal prioritized cycle rather than treated as an emergency - reassess immediately if it later appears in CISA KEV or a POC is published.

Exploit ScenarioDerived

A low-privileged ColdFusion user (e.g., a limited authenticated application account) crafts a request that coerces the ColdFusion server into making attacker-controlled requests to internal, otherwise unreachable resources, escalating their effective access and reading sensitive internal data. Because attack complexity is high, success depends on timing or configuration conditions outside the attacker's direct control. No public exploit identified at time of analysis.

AnalysisAIv1 – Oct 13, 2026

Server-side request forgery in Adobe ColdFusion 2023 (up to and including 2023.0.25) and ColdFusion 2025 (up to and including 2025.0.13) allows an authenticated low-privileged attacker to coerce the application server into issuing requests to internal resources, yielding elevated access and disclosure of data outside the attacker's intended scope. Adobe assigns this a CVSS 3.1 base score of 7.1 (AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:L/A:N); exploitation is non-deterministic because the vendor states success depends on conditions beyond the attacker's control, and it requires an existing foothold as a low-privileged account. There is no public exploit identified at time of analysis and no CISA KEV listing, so the practical risk profile is that of a moderate-severity, post-authentication SSRF rather than a remotely exploitable unauthenticated flaw.

RemediationAI

Adobe has published an advisory for this issue (APSB26-144, https://www.adobe.com/trust/security/products/coldfusion/apsb26-144.html) covering the ColdFusion 2023 and 2025 update channels, so the primary action is to apply the Adobe ColdFusion update that supersedes the affected builds - anything later than 2023.0.25 on the 2023 branch and later than 2025.0.13 on the 2025 branch - and confirm the installed build number after upgrading rather than relying on the updater exit code. Where patching must be deferred, the most effective compensating control for an SSRF is egress restriction: apply host or network firewall rules that deny outbound traffic from the ColdFusion server to internal RFC1918 ranges, loopback, link-local, and cloud instance-metadata endpoints (for example 169.254.169.254), allowing only the specific destinations ColdFusion genuinely needs - the trade-off is that legitimate integrations reaching internal services will break and must be explicitly allow-listed. Additionally, enforce IMDSv2 with hop-limit 1 on cloud instances to blunt metadata theft, reduce the number of low-privileged authenticated accounts that can reach the vulnerable functionality (since PR:L is a prerequisite, revoking unnecessary accounts directly removes the attack path), and monitor ColdFusion server logs and outbound connection logs for unexpected requests to internal hosts or unusual URL parameters. Web application firewall rules blocking or normalizing URL-bearing request parameters can raise the bar, but should be treated as a secondary layer because SSRF payloads are easily obfuscated. Note that blocking outbound traffic entirely is not viable for most deployments, so a documented, narrow egress allow-list with alerting is the preferred trade-off.

Technical ContextAI · show details

The issue is a server-side request forgery (SSRF) instance tracked as CWE-918 in Adobe ColdFusion. In this class of defect, attacker-controlled input that is meant to identify a resource is used by the server itself to construct an outbound HTTP (or similar) request, so the server acts as a proxy with its own network position and credentials rather than the attacker's. Because the ColdFusion application server typically sits behind the perimeter and can reach internal-only services, metadata endpoints, admin consoles, and adjacent hosts, a successful SSRF converts a low-privileged web session into a pivot that can read those internal resources. The CVSS vector confirms network reachability (AV:N) with no user interaction (UI:N), but requires a low-privileged authenticated account (PR:L), a high degree of attack complexity (AC:H) reflecting the vendor's statement that exploitation depends on conditions beyond the attacker's control, and a changed scope (S:C) indicating the vulnerable component grants access to resources beyond its own security authority. Confidentiality impact is high (C:H) because internal responses can be exfiltrated, integrity impact is limited (I:L), and there is no availability impact (A:N). The affected release trains are ColdFusion 2023 and ColdFusion 2025, both still within their supported update channels as of the referenced APSB26-144 advisory.

DescriptionCVE.org

ColdFusion is affected by a Server-Side Request Forgery (SSRF) vulnerability that could result in privilege escalation. A low-privileged attacker could exploit this vulnerability to gain elevated access to internal resources. Exploit depends on conditions beyond the attacker's control. Exploitation of this issue does not require user interaction. Scope is changed.

Executive ViewAI

Why It Matters

Adobe ColdFusion 2023 (through 2023.0.25) and ColdFusion 2025 (through 2025.0.13) deployments are affected by a high-severity server-side request forgery flaw that an authenticated low-privileged user could use to reach internal services and disclose data beyond their authorization. No public exploit identified at time of analysis and no vendor-released patch identified at time of analysis, so the immediate priority is containment, egress control, and monitoring rather than emergency patching. Leadership should care because affected systems may sit close to sensitive internal applications, and a single compromised low-privileged account could undermine network segmentation and data-access controls.

Business Impact: Medium
Compensating Controls

Restrict outbound network egress from ColdFusion servers to approved destinations, segment ColdFusion from sensitive internal services, enforce least privilege for ColdFusion accounts, monitor for anomalous server-side requests to internal endpoints, and apply Adobe hardening guidance until a vendor patch is released.

Attack Technique

Server-Side Request Forgery exploits applications that fetch remote resources based on user-supplied URLs.

Privilege escalation occurs when an attacker leverages flaws in access control mechanisms to gain permissions beyond what they were originally granted.
