Summary

CVE-2026-48285 is a Server-Side Request Forgery (SSRF) vulnerability in Adobe ColdFusion, rated High severity with a CVSS v3.1 base score of 8.6. The flaw affects ColdFusion 2025 (Update 9 and earlier) and ColdFusion 2023 (Update 20 and earlier), and can be exploited remotely by an unauthenticated attacker without any user interaction, resulting in security feature bypass and unauthorized read access. Adobe addressed the vulnerability in security bulletin APSB26-68, released June 30, 2026.

Technical details

  • Root cause: A Server-Side Request Forgery (SSRF) flaw (CWE-918) that allows an attacker to induce the ColdFusion server into making forged HTTP requests to internal or external resources on the attacker’s behalf.
  • Trigger conditions: No authentication is required (PR:N), no user interaction is needed (UI:N), and attack complexity is Low (AC:L) — the vulnerability is directly exploitable by any network-reachable attacker.
  • Attack vector: Network (AV:N); exploitable over the internet against any publicly exposed ColdFusion instance.
  • Impact: Security feature bypass and unauthorized read access. The Changed scope (S:C) indicates exploitation can affect resources beyond the vulnerable ColdFusion component itself. Confidentiality impact is High (C:H); integrity and availability are not impacted.

Affected software

  • Adobe ColdFusion 2025, versions 2025.9 (Update 9) and earlier
  • Adobe ColdFusion 2023, versions 2023.20 (Update 20) and earlier

Severity

CVSS v3.1 Base Score: 8.6 (High)
Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N

Mitigation and recommended actions

  • Immediate patch: Upgrade to Adobe ColdFusion 2025 Update 10 or Adobe ColdFusion 2023 Update 21, as provided in Adobe security bulletin APSB26-68.
  • If immediate patching is not feasible: Restrict network-level access to ColdFusion servers to trusted IP ranges only, and apply web application firewall controls to limit outbound server-initiated requests. Monitor ColdFusion server logs for anomalous outbound HTTP activity indicative of SSRF probing.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate patching. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
