DescriptionGitHub Advisory

Grav is a file-based Web platform. Prior to 1.8.0-beta.27, A path traversal vulnerability has been identified in Grav CMS, allowing authenticated attackers with administrative privileges to read arbitrary files on the underlying server filesystem. This vulnerability arises due to insufficient input sanitization in the backup tool, where user-supplied paths are not properly restricted, enabling access to files outside the intended webroot directory. The impact of this vulnerability depends on the privileges of the user account running the application. This vulnerability is fixed in 1.8.0-beta.27.

Analysis

Technical ContextAI

Path traversal allows an attacker to access files outside the intended directory by manipulating file paths with sequences like '../'.

RemediationAI

A vendor patch is available — apply it immediately. Validate and sanitize file path inputs. Use a whitelist of allowed files or directories. Implement chroot jails or containerization.
