CVE-2021-33816
The website builder module in Dolibarr 13.0.2 allows remote PHP code execution because of an incomplete protection mechanism in which system, exec, and shell_exec are blocked but backticks are not blocked.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.94%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
