MEDIUM5.3EPSS 0.30%Files added to tar with Phar::buildFromIterator have all-access permissions
Published: 2/27/2020Modified: 4/28/2026
Description
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.
