CVE-2021-3007: Getlaminas Laminas-HTTP

Critical severity, CVSS 9.8. EPSS: 75.3% chance of exploitation in the next 30 days.

Laminas Project laminas-http before 2.14.2, and Zend Framework 3.0.0, has a deserialization vulnerability that can lead to remote code execution if the content is controllable, related to the __destruct method of the Zend\Http\Response\Stream class in Stream.php. NOTE: Zend Framework is no longer supported by the maintainer. NOTE: the laminas-http vendor considers this a "vulnerability in the PHP language itself" but has added certain type checking as a way to prevent exploitation in (unrecommended) use cases where attacker-supplied data can be deserialized

Affected products

• Getlaminas Laminas-HTTP: before 2.14.2 (fixed in 2.14.2)
• Zend Zend Framework: version 3.0.0 only
