Symfony/Serializer handles serializing and deserializing data structures for Symfony, a PHP framework for web and console applications and a set of reusable PHP components. Symfony versions 4.1.0 before 4.4.35 and versions 5.0.0 before 5.3.12 are vulnerable to CSV injection, also known as formula injection. In Symfony 4.1, maintainers added the opt-in `csv_escape_formulas` option in the `CsvEncoder`, to prefix all cells starting with `=`, `+`, `-` or `@` with a tab `\t`. Since then, OWASP added 2 chars in that list: Tab (0x09) and Carriage return (0x0D). This makes the previous prefix char (Tab `\t`) part of the vulnerable characters, and OWASP suggests using the single quote `'` for prefixing the value. Starting with versions 4.4.34 and 5.3.12, Symfony now follows the OWASP recommendations and uses the single quote `'` to prefix formulas and add the prefix to cells starting by `\t`, `\r` as well as `=`, `+`, `-` and `@`.

Symfony potential Cross-site Scripting vulnerabilities in CodeExtension filters
### Description
Some Twig filters in CodeExtension use "is_safe=html" but don't actually ensure their input is safe.
### Resolution
Symfony now escapes the output of the affected filters.
The patch for this issue is available [here](https://github.com/symfony/symfony/commit/9da9a145ce57e4585031ad4bee37c497353eec7c) for branch 4.4.
### Credits
We would like to thank Pierre Rudloff for reporting the issue and to Nicolas Grekas for providing the fix.
