Operationally, ranked in the top 0.1% 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 are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
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.
