Deeper analysis
Abantecart through version 1.3.2 contains an unrestricted file upload vulnerability tracked as CVE-2022-26521 and CWE-434. The flaw resides in the Catalog > Media Manager > Images component, where an administrator can modify allowed file extensions to treat executable formats such as .php as valid image types, enabling upload of arbitrary code.
An attacker with remote authenticated administrator access can exploit the weakness to upload and execute malicious files on the server, resulting in arbitrary code execution with impacts to confidentiality, integrity, and availability. The CVSS 3.1 score of 7.2 reflects the requirement for high privileges but low attack complexity over a network.
Public references include proof-of-concept exploits on Packet Storm and GitHub demonstrating remote code execution against the affected versions. No official vendor advisories or patch details appear among the listed references.
EPSS for the CVE reached a peak of 0.1049 before receding to the current value of 0.0784, with public exploit code available since disclosure.

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.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
