Summary

CVE-2025-0502 is a medium-severity Resource Leak (CWE-402) vulnerability in Craftercms Craftercms. Its CVSS base score is 6.9 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 37th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to AC-3 (Access Enforcement) and AC-4 (Information Flow Enforcement) — see the control section below for these in your framework.

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

CVE-2025-0502 is a Transmission of Private Resources into a New Sphere ('Resource Leak') vulnerability in the CrafterCMS Engine, enabling Directory Indexing and Resource Leak Exposure. It affects CrafterCMS versions from 4.0.0 prior to 4.0.8 and from 4.1.0 prior to 4.1.6, across Linux, macOS, x86, Windows, 64-bit, and ARM platforms. The vulnerability carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H) and maps to CWE-402.

Remote unauthenticated attackers can exploit this vulnerability with low attack complexity and no user interaction. Exploitation grants access to private resources via directory indexing and leaks, leading to high-impact confidentiality loss through exposure of sensitive data and high-impact availability disruption.

The official CrafterCMS security advisory provides mitigation guidance at https://craftercms.com/docs/current/security/advisory.html#cv-2025011501. Affected systems should be upgraded to CrafterCMS 4.0.8 or later, or 4.1.6 or later, to address the issue.

Mitigating Controls (NIST 800-53 r5) AI

AC-4 Information Flow Enforcement good match

Explicitly enforces information-flow rules that block private resources from reaching unauthorized external spheres.

AC-3 Access Enforcement good match

Enforces approved authorizations so private resources cannot be transmitted outside their intended sphere.

SC-7 Boundary Protection partial match

Boundary controls monitor and restrict communications that would otherwise leak private resources.

SC-8 Transmission Confidentiality and Integrity partial match

Requires confidentiality protection on transmitted data, directly stopping exposure of private resources.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.AA-05 mostly match
prevents

Enforcing least-privilege access permissions directly prevents private resources from being exposed outside their intended sphere.

PR.IR-01 mostly match
prevents

Logical segmentation and unauthorized-access protections stop resources from leaking into untrusted domains.

PR.DS-01 partial match
prevents

Encryption of data-at-rest reduces the value of any leaked resource but does not address the transmission flaw itself.

PR.DS-02 partial match
prevents

Protecting data-in-transit mitigates exposure during movement yet does not prevent the underlying boundary violation.

A.8.3 Information access restriction full match
prevents

Information-access-restriction directly prevents private resources from being exposed beyond intended boundaries.

A.5.15 Access control mostly match
prevents

Access-control mechanisms limit who can receive resources that should remain internal.

A.5.18 Access rights mostly match
prevents

Managing access rights helps ensure resources are not granted to untrusted parties.

A.8.12 Data leakage prevention mostly match
finds

Data-leakage-prevention technologies specifically block unintended transmission of sensitive resources.

A.5.14 Information transfer partial match
mitigates

Information-transfer rules can prevent unintended disclosure of private resources outside the product.

A.8.20 Networks security partial match
mitigates

Network-security controls can limit exposure paths but do not address the root resource-leak logic.
