What is CVE-2026-108705?

CordysCRM versions up to 1.9.3 are susceptible to a missing authorization vulnerability that affects the POST /custom-form/data/import endpoint. This flaw enables authenticated users, including those with low privileges, to exploit the customFormId parameter, thereby allowing unauthorized data imports. Attackers can upload Excel files with specified import types (ADD or UPDATE), leading to unauthorized creation of new records or overwriting existing ones within custom forms they do not possess permission to manage.

Affected Version(s)

CordysCRM 0 <= 1.9.3

Exploit Proof of Concept (PoC)
