CVE-2026-90530 — ColdFusion | Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22)

ColdFusion RDS is affected by an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability that could lead to arbitrary file system read. An attacker could exploit this vulnerability to access sensitive files and directories outside the intended access scope. Exploitation of this issue does not require user interaction. Scope is changed. RDS is purely a development feature meant for debugging purposes, and switching ColdFusion to Production Secure Profile automatically disables RDS. The Lockdown Guide outlines the specific step to disable RDS if a ColdFusion server is not being used in Production Secure Profile.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.3% (30-day exploitation probability)+3
  • Technical severity (critical)+10

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Adobe ColdFusion 2023, Adobe ColdFusion 2025).
  2. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  3. Search available logs for exploit probes matching the vulnerability class (file handling), errors and authentication anomalies.

What should defenders know first?

CVE-2026-90530 is "ColdFusion | Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22)", rated Critical. It affects ColdFusion 2023 (Adobe); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 9.3 describes technical severity. EPSS 0.27% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
