Summary
CVE-2025-47787 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Emlog Emlog. Its CVSS base score is 8.9 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Web Shell (T1505.003); ranked in the top 45% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Emlog Pro, an open source website building system, is affected by a file upload vulnerability in versions prior to 2.5.10. The issue resides in the store.php component, which fails to properly validate the contents of remotely downloaded ZIP plugin files, corresponding to CWE-434 and resulting in a CVSS 4.0 score of 8.9.
Unauthenticated attackers with network access can exploit the flaw to upload and execute arbitrary code on the target system by supplying malicious plugin archives that bypass content checks.
The referenced GitHub security advisory GHSA-4mcj-8gvh-p753 and associated commit confirm that version 2.5.10 resolves the vulnerability through improved validation of downloaded plugin files.
The EPSS score remains flat at 0.0180 with no material increase after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

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.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Hardened configuration baselines can enforce allowed file types and processing rules.
Secure development practices include input validation and file-type restrictions that prevent this weakness.
