Cross Site Request Forgery vulnerability in ProcessWire v.3.0.229 allows a remote attacker to execute arbitrary code via a crafted HTML file to the comments functionality.
An issue found in ProcessWire 3.0.210 allows attackers to execute arbitrary code and install a reverse shell via the download_zip_url parameter when installing a new module. NOTE: this is disputed because exploitation requires that the attacker is able to enter requests as an admin; however, a ProcessWire admin is intentionally allowed to install any module that contains any arbitrary code.
ProcessWire v3.0.200 was discovered to contain multiple cross-site scripting (XSS) vulnerabilities via the Search Users and Search Pages function. These vulnerabilities allow attackers to execute arbitrary web scripts or HTML via injection of a crafted payload.
