Adobe has released an urgent set of security updates to address multiple vulnerabilities within its ColdFusion 2025 and 2023 versions. The patches resolve a range of critical and moderate security gaps that could lead to devastating outcomes for enterprise servers, including Remote Code Execution (RCE) and total security feature bypasses.
The most severe of these vulnerabilities could allow an attacker to seize control of a system without needing prior authorization, though Adobe notes that it is currently “not aware of any exploits in the wild” for these issues.
The update addresses several high-impact flaws that represent a significant risk to the integrity and confidentiality of ColdFusion deployments.
- Arbitrary Code Execution (CVE-2026-27304 & CVE-2026-27306): These critical flaws are the result of improper input validation (CWE-20). With the CVSS score of 9.3 & 8.4, they allow a malicious actor to execute arbitrary code on the server, potentially leading to a complete system takeover.
- Path Traversal (CVE-2026-34619): Rated as critical with a CVSS score of 7.7, this vulnerability involves the improper limitation of a pathname to a restricted directory. Attackers could leverage this to bypass critical security features and gain unauthorized access to protected system files.
- Security Feature Bypass (CVE-2026-27282): Another critical input validation error (CWE-20) with a CVSS score of 7.5 allows attackers to circumvent established security protocols within the application.
Beyond the high-profile RCE and bypass flaws, the update also mitigates a series of moderate vulnerabilities. One such issue, CVE-2026-27307, involves uncontrolled resource consumption which could be weaponized to trigger an Application Denial-of-Service (DoS), effectively knocking the server offline.
Overall, the vulnerabilities addressed in this release have the potential to:
- Execute arbitrary code remotely.
- Bypass security feature protocols.
- Allow arbitrary file system reads.
- Cause application-level denial-of-service.
Given the critical nature of these flaws—particularly the potential for code execution—administrators are urged to apply the security updates for ColdFusion versions 2025 and 2023 provided by Adobe.
