How to Fix CVE-2022-23601
To remediate this vulnerability, upgrade all affected Symfony/framework bundle dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Upgrade symfony/framework-bundle to 5.3.15Upgrade symfony/framework-bundle to 5.4.4Upgrade symfony/framework-bundle to 6.0.4Run the following command in your project directory to verify that all resolved dependencies use the patched release:
inspect dependencies for symfony/framework-bundleHow to Check if You Are Affected
To determine whether your application is affected by CVE-2022-23601, inspect your project dependencies for Symfony/framework bundle:
inspect dependencies for symfony/framework-bundleAnalyze the terminal output to locate any version of Symfony/framework bundle in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 5.3.15), your application is affected.
Note: Verify declared build manifests and deployed runtime container environments.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-352: Cross-Site Request Forgery (CSRF), where the web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor. In Symfony/framework bundle, software state validation or input boundaries are circumvented during processing.

"details" : "Description\n-----------\n\nThe Symfony form component provides a CSRF protection mechanism by using a random token injected in the form and using the session to store and control the token submitted by the user.\nWhen using the FrameworkBundle, this protection can be enabled or disabled with the configuration. If the configuration is not specified, by default, the mechanism is enabled as long as the session is enabled.\n\nIn a recent change in the way the configuration is loaded, the default behavior has been dropped and, as a result, the CSRF protection is not enabled in form when not explicitly enabled, which makes the application sensible to CSRF attacks.\n\nResolution\n----------\n\nSymfony restored the default configuration to enable the CSRF protection by default.\n\nThe patch for this issue is available [here](https://github.com/symfony/symfony/commit/f0ffb775febdf07e57117aabadac96fa37857f50) for branch 5.3.\n\nCredits\n-------\n\nWe would like to thank Catalin Dan and David Lochner for reporting the issue and Jérémy Derussé for fixing the issue.",
