CVE-2025-30284
Published: 08 April 2025
Summary
CVE-2025-30284 is a high-severity Deserialization of Untrusted Data (CWE-502) vulnerability in Adobe Coldfusion. Its CVSS base score is 8.4 (High).
Operationally, ranked in the top 22.2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis
ColdFusion versions 2023.12, 2021.18, 2025.0 and earlier contain a Deserialization of Untrusted Data vulnerability that permits arbitrary code execution in the context of the current user. The flaw is tracked as CWE-502 and carries a CVSS 3.1 score of 8.4 reflecting network attack vector, low attack complexity, high privileges required, required user interaction, and changed scope with high impact on confidentiality, integrity, and availability.
A high-privileged attacker can leverage the issue to bypass security protections and execute code, although successful exploitation depends on user interaction. The vulnerability therefore allows an authenticated administrator who convinces a victim to perform a specific action to obtain code execution outside the original security context.
Adobe’s security bulletin APSB25-15 at https://helpx.adobe.com/security/products/coldfusion/apsb25-15.html addresses the issue and supplies remediation guidance. The associated EPSS score rose materially from a low baseline to a peak of 0.3001 on 2026-01-13 before receding to the current value of 0.0103, indicating that exploitation interest appeared after disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Penetration testing supplies malicious serialized objects, detecting unsafe deserialization and supporting corrective actions.
Evaluation of untrusted data handling (deserialization testing) reveals unsafe processing, which the required remediation process addresses.
Untrusted serialized data can be deserialized and observed inside the chamber, blocking gadget-chain exploitation outside the sandbox.
Validates or rejects untrusted serialized data before deserialization occurs.
Identifies and blocks malicious code introduced through deserialization of untrusted data at system boundaries.
Integrity verification of serialized information can detect tampering before deserialization occurs.
Provenance of associated data allows detection of untrusted sources before deserialization or processing occurs.
