TYPO3 installations using the so-called ***Classic Mode*** **are not affected**. **Do I have a** ***Composer-based*** **or a** ***Classic Mode*** **TYPO3 Installation?** Along with many other popular PHP-based software platforms, TYPO3’s dependency system is based on the [Composer](https://getcomposer.org) dependency manager. In a ***Composer-based*** installation, you use the *composer* command in the command line, it calculates the optimal library and extension versions for your system and loads them dynamically into your TYPO3 installation. TYPO3's ***Classic Mode*** is a TYPO3 installation created from pre-packaged files, often downloaded as a .zip or .tar.gz file. This file is made available without system-specific optimizations and uses TYPO3's built-in Extension Manager to download and upgrade extension. It has been discovered that, for a limited time, a weak dependency range in the composer package [*symfony/type-info*](https://packagist.org/packages/symfony/type-info) caused an incompatible version of their optional dependency [*phpstan/phpdoc-parser*](https://packagist.org/packages/phpstan/phpdoc-parser) to be installed. This caused Extbase runtime errors on all TYPO3 instances that have been updated in the mentioned date range if they used [Extbase](https://docs.typo3.org/m/typo3/reference-coreapi/main/en-us/ExtensionArchitecture/Extbase/Index.html) plugins. Please see [TYPO3 bug report #105582](https://forge.typo3.org/issues/105582) for more information. [TYPO3 released a hotfix of the *typo3/cms-cli* package](https://github.com/TYPO3/cms-cli/releases/tag/3.1.2) (version 3.1.2) on Wednesday, 13 November 2024 12:40 UTC. This release ensures that subsequent updates are not affected. We recommend everyone who updated TYPO3 between the mentioned dates to perform a downgrade to *phpstan/phpdoc-parser* version 1 by running this Composer command: ``` composer update phpstan/phpdoc-parser --with "phpstan/phpdoc-parser:^1" ``` As of 13 November 2024 14:52 UTC, this issue has also been [fixed upstream by Symfony](https://github.com/symfony/symfony/releases/tag/v7.1.8) (version 7.1.8). ![](https://news.typo3.com/typo3temp/assets/t3g/blog/gravatar/d2f68d86720b93361f6910922465f559.jpeg) About the Author [Benni Mack](https://news.typo3.com/article/author/benni-mack) CTO at b13,Stuttgart, Germany [Website](https://b13.com/)[Twitter](https://twitter.com/bennimack)[LinkedIn](https://www.linkedin.com/in/benjaminmack/) Being the CTO at b13 GmbH, Benni is the TYPO3 Core Project Lead and one of the driving forces behind the TYPO3 community in the last years.
