Details
As written in the advisory (Markdown source, shown as plain text).
An issue was discovered in Symfony before 4.2.12 and 4.3.x before 4.3.8. The VarExport component incorrectly escapes strings, allowing some specially crafted ones to escalate to execution of arbitrary PHP code. This is related to symfony/var-exporter.
