CVE-2024-28859

Summary

CVE-2024-28859 is a vulnerability affecting Symfony1, a community fork of Symfony 1.4. Due to a SWift Mailer dependency, this software is susceptible to a gadget chain attack. If a developer unsuspectingly deserializes untrusted user data, an attacker can exploit this vulnerability to execute remote code. The root cause lies in the ability to manipulate the `$this->_keys` property in Swift Mailer classes, allowing unintended array or object property access. This issue, which can lead to remote code execution, is present in Swift Mailer classes implemented with the ArrayAccess interface. Although it poses no direct threat, users are strongly advised to upgrade to version 1.5.18 to mitigate this vulnerability, as no known workarounds are available.
