CVE-2020-11033Network attack vector

Token disclosure via incomplete API field filtering

Published May 5, 2020 · Updated Aug 4, 2024

Information disclosure in GLPI 9.1 through 9.4.5 allows remote authenticated users to obtain other users' API and personal tokens. The User item API serializes complete user records while its field filter removes only passwords, leaving personal_token and api_token in responses. Exploitation requires an enabled API and a technician account with READ access to User items; exposed API tokens permit unauthorized data operations, while personal tokens reveal planning data.
