CVE-2021-39213

GLPI is a free Asset and IT management software package. Starting in version 9.1 and prior to version 9.5.6, GLPI with API Rest enabled is vulnerable to API bypass with custom header injection. This issue is fixed in version 9.5.6. One may disable API Rest as a workaround.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
