![]() ![]() This vulnerability also applies to the Pulsar Broker when it is configured with "functionsWorkerEnabled=true". This could allow an attacker to create or modify files outside of the designated extraction directory, potentially influencing system behavior. This occurs when the filenames in the zip files, which aren't properly validated, contain special elements like ".", altering the directory path. However, if a malicious file is uploaded, it could exploit a directory traversal vulnerability. These files, essentially zip files, are extracted by the Functions Worker. In Pulsar Functions Worker, authenticated users can upload functions in jar or nar files. (A patch is available as of release 0.1.29 of langchain-core.) The outcome can be disclosure of an API key for a large language model online service, or remote code execution. This bypasses the intended behavior of loading configurations only from the hwchase17/langchain-hub GitHub repository. directory traversal by an actor who is able to control the final part of the path parameter in a load_chain call. There are no known workarounds for this vulnerability. ![]() This issue has been addressed in version 1.5.18. This may allow an attacker to execute any PHP command which leads to remote code execution. ![]() ) for any class implementing ArrayAccess interface. In particular, it is possible to abuse the array access which is triggered on foreach($this->_keys. However, it is possible to include any object type in `$this->_keys` to make PHP access to another array/object properties than intended by the developer. These methods are called when php destroys the object in memory. Swift Mailer classes implement some `_destruct()` methods. Symfony 1 depends on Swift Mailer which is bundled by default in vendor directory in the default installation since 1.3.0. This vulnerability present no direct threat but is a vector that will enable remote code execution if a developper deserialize user untrusted data. Symfony 1 has a gadget chain due to vulnerable Swift Mailer dependency that would enable an attacker to get remote code execution if a developer unserialize user input in his project. Symfony1 is a community fork of symfony 1.4 with DIC, form enhancements, latest Swiftmailer, better performance, composer compatible and PHP 8 support. ![]()
