Adobe released security updates for Adobe ColdFusion and Adobe Campaign Classic to fix multiple vulnerabilities that could let attackers bypass security controls, manipulate files, gain elevated privileges, or execute arbitrary commands. The most severe issue, CVE-2026-48276, is an unrestricted file upload flaw in ColdFusion with a CVSS 10.0 rating that can lead to remote code execution, while CVE-2026-48315 is an improper input validation bug rated CVSS 9.3 that can enable privilege escalation.
CISA later added the ColdFusion flaw to its Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild and elevating the issue to an urgent remediation priority for organizations running internet-facing ColdFusion servers. Reporting on the KEV update said the vulnerability can contribute to full server compromise, and urged defenders to patch affected systems quickly, investigate for signs of compromise, and prioritize exposed web applications and related enterprise platforms over CVSS-only risk scoring.

Adobe disclosed two high-severity vulnerabilities in **ColdFusion** that affect versions **2023.18, 2025.6, and earlier**. The first, `CVE-2026-27304`, is an improper input validation flaw (`CWE-20`) that can lead to **arbitrary code execution** in the context of the current user without requiring user interaction. Adobe assigned the issue a CVSS v3.1 vector of `AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N` and published details in security bulletin **APSB26-38**. Adobe also disclosed `CVE-2026-27305`, a **path traversal** vulnerability (`CWE-22`) in the same ColdFusion versions that allows an unauthenticated remote attacker to perform **arbitrary file system reads** and access sensitive files outside intended directories. The flaw likewise requires no user interaction and carries a CVSS v3.1 vector of `AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N`, making the pair of issues a significant risk for exposed ColdFusion deployments.

Adobe ColdFusion is facing active exploitation of **CVE-2026-48282**, a maximum-severity flaw tied to **RDS arbitrary file write** that can be abused without privileges on unpatched servers. The Canadian Centre for Cyber Security warned that open-source reporting indicates in-the-wild attacks, while Adobe has issued security updates and urged administrators to patch immediately because of the high risk of compromise. Affected releases include **ColdFusion 2025.9, 2023.20, and earlier**, and internet scanning data from Shadowserver shows nearly **800** ColdFusion instances exposed online, though the number still vulnerable is unclear. Separate reporting on **CVE-2026-48276** highlights a closely related ColdFusion attack path in which an unauthenticated attacker uploads a malicious **CFML** payload through an unrestricted file-upload weakness, writes a web shell into a web-accessible location, and then triggers it with an HTTP request to gain code execution. That issue was described as critical with a **CVSS v3.1** score reflecting full impact to confidentiality, integrity, and availability, and its documented root causes included poor filename and extension validation and storing uploads under the web root. Public detection content has also appeared for **CVE-2026-48282**, underscoring defender focus on identifying exposed and unpatched ColdFusion systems.

Adobe has released Priority 1 security updates for **ColdFusion** and **Adobe Campaign Classic** to fix multiple high-severity vulnerabilities, including seven flaws rated `CVSS 10.0`. In ColdFusion, the patched issues affect versions `2025.9`, `2023.20`, and earlier, and include improper input validation (`CVE-2026-48281`, `CVE-2026-48277`), unrestricted file upload (`CVE-2026-48276`, `CVE-2026-48283`), and path traversal (`CVE-2026-48282`) bugs that could allow unauthenticated remote code execution without user interaction. Additional ColdFusion flaws include a path traversal issue with arbitrary file read and limited write access (`CVE-2026-48313`), an SSRF bug (`CVE-2026-48285`), and user-interaction issues such as reflected XSS (`CVE-2026-48307`) and improper input validation tied to malicious files (`CVE-2026-48315`). Adobe also patched `CVE-2026-48286` in **Adobe Campaign Classic**, an incorrect authorization flaw affecting version `7.4.3` and earlier that can lead to arbitrary code execution on on-premises instances. Adobe said it is not aware of in-the-wild exploitation of the specific vulnerabilities, but assigned the updates a **Priority 1** rating, indicating they are being targeted or are at high risk of being targeted, and urged administrators to patch within 72 hours. Recommended versions include **ColdFusion 2025 Update 10**, **ColdFusion 2023 Update 21**, and **Campaign Classic 7.4.4 / build 9397 or later**.
