CVE-2019-11325: Fix escaping of strings in VarExporter
Symfony 4.2.0 to 4.2.11 and 4.3.0 to 4.3.7 versions of the Symfony VarExporter component are affected by this security issue.
The issue has been fixed in Symfony 4.2.12 and 4.3.8.
Some strings were not properly escaped when being dumped by the VarExporter component. The VarExporter is notably used by the Symfony Cache Component
The escaping logic has been fixed to work for any strings.
The patch for this issue is available here for branch 4.2.
I would like to thank Seung Woo Yuk (xtac) for reporting & Nicolas Grekas for identifying & fixing the issue.
