Exposed phpinfo() leadked via documentation files
Impact
The phpinfo() can be exposed if the /vendor is not protected from public access. This is a rare situation today since the vendor directory is often located outside the web directory or protected via server rule (.htaccess, etc).
Patches
Only the v6, v7 and v8 will be patched respectively in 8.0.7, 7.1.2, 6.1.5. Older versions such as v5, v4 are not longer supported and will NOT be patched.
Workarounds
Protect the /vendor directory from public access.
