Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.9% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Adobe ColdFusion versions 2018 Update 15 and earlier, along with 2021 Update 5 and earlier, are affected by a path traversal vulnerability tracked as CWE-22. The flaw permits arbitrary file system reads and carries a CVSS 4.9 rating reflecting network accessibility, low attack complexity, and high confidentiality impact when successfully exploited.

An authenticated administrator can leverage the issue without user interaction to read arbitrary files on the server. No other privileges or special conditions are required beyond the administrative account.

Adobe published mitigation guidance and patch information in advisory APSB23-25, available at https://helpx.adobe.com/security/products/coldfusion/apsb23-25.html.

The associated EPSS score rose from a lower baseline to a peak of 0.3213 on 2025-12-11 before receding to the current value of 0.1289, indicating a period of increased exploitation interest after disclosure.

Likely Mitigating Controls AI

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.

addresses: CWE-22

Validates pathnames and filenames to prevent traversal outside intended directories.

PR.PS-02 partial match
prevents

Patching/maintenance can remediate known path-traversal flaws in deployed software (partial prevention of exploitability) but does nothing to stop the coding defect from being introduced in the first place.

PR.AA-05 none match
prevents

PR.AA-05 defines and reviews access policies but does not address code-level pathname neutralization, so neither direction prevents CWE-22.

finds

Security testing in development catches path traversal via static/dynamic analysis.

prevents

Secure SDLC mandates input validation and path sanitization that directly prevent path traversal.

prevents

Application security requirements include rules for safe file handling and canonicalization.

prevents

Secure architecture principles require least-privilege file access and directory isolation.

prevents

Secure coding standards explicitly forbid unsafe path construction and mandate safe APIs.

mitigates

Information access restriction limits which files an application may read or write.
