Vulnerability in Lever PDF Embedder Plugin for WordPress
CVE-2019-19589
9.8CRITICAL
What is CVE-2019-19589?
The Lever PDF Embedder plugin version 4.4 for WordPress does not effectively restrict the serving of polyglot PDF files that can masquerade as valid JAR archives. This oversight can lead to the potential execution of malicious code if an attacker successfully uploads such a file. It's important to note that the vulnerability arises primarily from the WordPress core's file upload handling, not directly from the PDF Embedder plugin. Users must ensure proper management of uploaded files to mitigate risks associated with polyglot files.
