SCA: security update for flarum/core (GHSA-vhm8-wwrf-3gcw)

medium Tenable Self-Hosted Container Security Plugin ID 419359

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - flarum is a forum software package for building communities. In versions prior to 1.7.0 an admin account
 which has already been compromised by an attacker may use a vulnerability in the `LESS` parser which can
 be exploited to read sensitive files on the server through the use of path traversal techniques. An
 attacker can achieve this by providing an absolute path to a sensitive file in the custom `LESS` setting,
 which the `LESS` parser will then read. For example, an attacker could use the following code to read the
 contents of the `/etc/passwd` file on a linux machine. The scope of what files are vulnerable will depend
 on the permissions given to the running flarum process. The vulnerability has been addressed in version
 `1.7`. Users should upgrade to this version to mitigate the vulnerability. Users unable to upgrade may
 mitigate the vulnerability by ensuring that their admin accounts are secured with strong passwords and
 follow other best practices for account security. Additionally, users can limit the exposure of sensitive
 files on the server by implementing appropriate file permissions and access controls at the operating
 system level. (CVE-2023-27577)
