Description Preview

An issue was discovered in the ownCloud graphapi app versions 0.2.x before 0.2.1 and 0.3.x before 0.3.1. The vulnerability arises from the reliance on a third-party GetPhpInfo.php library, which, when accessed, discloses the PHP environment's configuration details (phpinfo). This information includes all environment variables of the web server, which in containerized deployments may contain sensitive data like the ownCloud admin password, mail server credentials, and license keys. Disabling the graphapi app does not mitigate the vulnerability, and the exposure of phpinfo can lead to further exploitation by attackers. This vulnerability is critical, with a CVSS score of 10, indicating a high impact on confidentiality, integrity, and availability.
