AI Analysis
Technical Summary
CVE-2026-55885 is a vulnerability in the Grav file-based web platform where an authenticated administrator with backup permissions can exploit the backup download endpoint to obtain a ZIP archive of the entire Grav installation root. This archive contains sensitive information including the administrator password hash and site configuration files. The endpoint's protection relies solely on a session-static admin-nonce URL parameter, which is insufficient to prevent unauthorized access to these sensitive files. The vulnerability is addressed in Grav version 1.7.53.
Potential Impact
An attacker with authenticated administrator access and backup permissions can obtain sensitive information such as password hashes and site configuration by downloading the full Grav installation root. This exposure can lead to credential compromise and further security risks. The vulnerability does not affect confidentiality beyond the administrator scope and does not impact integrity or availability directly.
Mitigation Recommendations
Upgrade Grav to version 1.7.53 or later, where this vulnerability has been fixed. No other mitigation is indicated by the vendor advisory. Patch status is confirmed fixed in 1.7.53.
