CVE-2026-48282

CVE-2026-48282 is a path traversal vulnerability (CWE-22) in Adobe ColdFusion. It is triggered by crafted file-path input containing directory-traversal sequences that the application fails to constrain, allowing access outside the intended directory; per CISA this can escalate to arbitrary code execution in the context of the current user. Successful exploitation could give an attacker the ability to run code on the ColdFusion host under the ColdFusion service account, a common foothold for further network compromise. All organizations running affected Adobe ColdFusion releases, particularly internet-facing instances, are in scope; the specific affected version ranges have not been detailed in the available data. The flaw is already being exploited in the wild: it was added to CISA's Known Exploited Vulnerabilities catalog on 2026-07-07 and carries a 42.4% EPSS probability of exploitation within 30 days (99th percentile), though no public PoC is known and ransomware use is unconfirmed.

What to do: Inventory all Adobe ColdFusion deployments, prioritizing internet-facing servers, and apply the vendor patch per Adobe's security advisory since the affected version ranges are not yet specified in this data. Federal agencies must patch or apply mitigations in accordance with CISA BOD 26-04 within the KEV deadline or discontinue use if mitigations are unavailable. Until patched, restrict external access to ColdFusion instances and consider WAF/IPS rules blocking directory-traversal sequences in file-path parameters.
