Symfony 7.4.22 fixes four CVEs: CVE-2026-109449 bounds the nesting level of parsed expressions in ExpressionLanguage, CVE-2026-108082 removes ambiguity causing HeaderUtils::split() to backtrack in HttpFoundation, CVE-2026-45070 rejects parameter names with non-token characters in Mime, and CVE-2026-109413 bounds recursion depth in the Yaml inline lexer. _Developers patching Symfony apps can track CVE fixes like these on daily.dev._ ### Does Symfony 7.4.22 fix issues with the Redis Messenger transport? Yes, Symfony 7.4.22 fixes the Redis transport after a lost connection, prevents losing delayed Redis messages on migration failure, and allows installing the Redis bridge with only ext-relay. These changes target reliability problems in Messenger's Redis integration under connection failures. _Teams running Messenger on Redis can follow fixes like these on daily.dev before upgrading._ --- Tags: [#php](https://daily.dev/tags/php), [#symfony](https://daily.dev/tags/symfony) [View this post on daily.dev](https://daily.dev/posts/symfony-7-4-22-released-symfony-blog--2i49tr9tj) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Symfony 7.4.22 released (Symfony Blog)","url":"https://daily.dev/posts/symfony-7-4-22-released-symfony-blog--2i49tr9tj","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/symfony-7-4-22-released-symfony-blog--2i49tr9tj"},"datePublished":"2026-10-28T18:25:50.614Z","dateModified":"2026-10-28T18:40:51.923Z","description":"Symfony 7.4.22 is out, a patch release fixing dozens of bugs across the framework plus four security issues.
