SCA: security update for getgrav/grav (GHSA-m8vh-v6r6-w7p6)
medium Tenable Cloud Security Plugin ID 437134
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Grav is a file-based Web platform. Prior to 1.8.0-beta.27, a Denial of Service (DoS) vulnerability was
identified in the "Languages" submenu of the Grav admin configuration panel (/admin/config/system).
Specifically, the Supported parameter fails to properly validate user input. If a malformed value is
inserted—such as a single forward slash (/) or an XSS test string—it causes a fatal regular expression
parsing error on the server. This leads to application-wide failure due to the use of the preg_match()
function with an improperly constructed regular expression, resulting in an error. Once triggered, the
site becomes completely unavailable to all users. This vulnerability is fixed in 1.8.0-beta.27.
