Tracked as <strong><a href=\"https:\/\/nvd.nist.gov\/vuln\/detail\/CVE-2026-48282\" target=\"_blank\" rel=\"noopener\">CVE-2026-48282<\/a><\/strong> and rated CVSS 10.0, the flaw lets an unauthenticated attacker achieve remote code execution &mdash; and federal agencies were given only until July 10 to patch under Binding Operational Directive 26-04.<\/p>\n<h2>Path traversal in the RDS handler, leading to unauthenticated RCE<\/h2>\n<p>CVE-2026-48282 is an improper path-limitation flaw (CWE-22) in ColdFusion&#8217;s Remote Development Services (RDS) FILEIO handler. Because the handler fails to properly validate paths, an unauthenticated attacker can write arbitrary files anywhere on the server&#8217;s file system &mdash; including the web root. Dropping a malicious file into a web-accessible directory turns that file-write into full, unauthenticated remote code execution. No login and no user interaction are required, which is exactly why it earns a perfect 10.0.<\/p>\n<h2>Patched June 30, exploited by July 7<\/h2>\n<p>Adobe shipped fixes on June 30, 2026 for the ColdFusion 2023 and 2025 release lines. One week later, CISA confirmed active exploitation and added the CVE to KEV with a three-day remediation deadline. That compressed timeline is a signal in itself &mdash; CISA reserves the tightest windows for bugs being weaponized right now. ColdFusion also has a long history of being targeted: its RCE flaws are a recurring favorite of ransomware operators and initial-access brokers.<\/p>\n<h2>\u4eca\u3059\u3050\u53d6\u308b\u3079\u304d\u5bfe\u5fdc<\/h2>\n<p>If you run Adobe ColdFusion 2023 or 2025, apply the June 30 security updates immediately. Beyond patching, Remote Development Services should never be exposed to the internet: disable RDS in production if it is not needed, and restrict access to ColdFusion administration interfaces. Because exploitation is unauthenticated and leads directly to code execution, treat any internet-facing ColdFusion server that stayed unpatched after June 30 as potentially compromised, and hunt for unexpected files in web-accessible directories.<\/p>","protected":false},"excerpt":{"rendered":"<p>CISA added the actively exploited Adobe ColdFusion RDS path-traversal flaw CVE-2026-48282 (CVSS 10.0)
