CVE-2020-7063  (opens in a new tab)
CWE-281  (opens in a new tab)

How to fix?

Upgrade php to version 7.2.29, 7.3.15, 7.4.3 or higher.

Overview

Affected versions of this package are vulnerable to Improper Preservation of Permissions. In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when creating PHAR archive using PharData::buildFromIterator() function, the files are added with default permissions (0666, or all access) even if the original files on the filesystem were with more restrictive permissions. This may result in files having more lax permissions than intended when such archive is extracted.
