CVE-2020-7063 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. 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.. EPSS estimates a 1.60% chance of exploitation in the next 30 days.
