CVE-2026-72698: Exposure of Sensitive Information to an Unauthorized Actor in getgrav grav
Grav CMS versions before 2.0.16 contain a vulnerability where sandboxed Twig renders do not properly filter system, site, and theme configuration arrays. This allows content editors with page-content edit access to read sensitive configuration values, including secrets such as cache credentials, by using dot notation in Twig templates. The vulnerability bypasses config_denied_paths restrictions, exposing sensitive information to unauthorized actors.
AI Analysis
Technical Summary
CVE-2026-72698 is a high-severity vulnerability in Grav CMS prior to version 2.0.16. The issue arises because the system, site, and theme configuration arrays are not filtered in sandboxed Twig renders, enabling users with page-content edit permissions to access raw configuration data. Attackers can exploit this by using dot notation in Twig templates to bypass config_denied_paths restrictions and extract sensitive configuration values including secrets like cache credentials. This exposure of sensitive information can lead to further compromise depending on the disclosed data.
Potential Impact
Unauthorized actors with page-content edit access can read sensitive configuration data, including secrets such as cache credentials, which should be protected. This exposure can facilitate further attacks or unauthorized access to system components relying on these secrets. The vulnerability does not require user interaction and has a low attack complexity, increasing its risk.
Mitigation Recommendations
No official fix or patch is currently confirmed. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict page-content edit permissions to trusted users only to minimize risk.
