CVE-2024-34102 is a critical-severity Improper Restriction of XML External Entity Reference (CWE-611) vulnerability in Adobe Commerce. Its CVSS base score is 9.8 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 0.0% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified map to CM-6 (Configuration Settings) and SA-11 (Developer Testing and Evaluation) — 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.
Adobe Commerce versions 2.4.7, 2.4.6-p5, 2.4.5-p7, 2.4.4-p8 and earlier contain an XXE vulnerability (CWE-611) that permits arbitrary code execution. The flaw stems from improper restriction of XML external entity references and carries a CVSS 3.1 score of 9.8, reflecting network-accessible attack vectors that require no authentication or user interaction.
An unauthenticated attacker can send a crafted XML document containing malicious external-entity references directly to the affected application, resulting in full compromise of confidentiality, integrity, and availability. Exploitation does not depend on any prior foothold or victim action.
Adobe’s APSB24-40 advisory addresses the issue, and the vulnerability appears in CISA’s Known Exploited Vulnerabilities catalog. The associated EPSS score has reached a peak of 0.9733 with a current value of 0.9417, indicating sustained and substantial exploitation interest following disclosure.

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.
Hardened XML parser configurations directly disable external entity resolution.
Secure SDLC practices include input validation and safe XML parser configuration that prevent XXE.
Vulnerability scanning can discover XXE flaws but does not prevent their introduction in code.
Patching eliminates XXE-vulnerable parser versions but is only one aspect of software maintenance.

Security testing in development catches XXE via static analysis and dynamic XML fuzzing.
Vulnerability management identifies and patches XML libraries with unsafe default entity settings.
Secure development life cycle mandates input validation and entity handling that directly prevents XXE.
Application security requirements explicitly call for disabling external entity processing in XML parsers.
Secure architecture principles include safe parser configuration that mitigates external entity risks.
Secure coding standards require disabling DTDs and external entities in XML processing.
