What the vulnerability does
01Description
The News Flash theme for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.1.0 via deserialization of untrusted input from the newsflash_post_meta meta value. This makes it possible for authenticated attackers, with Editor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
Explanation of Vulnerability in Simple Terms
02Summary
News Flash versions up to 1.1.0 contain a deserialization vulnerability that allows authenticated administrators to execute arbitrary code on the site. An attacker with admin privileges can craft malicious serialized data that, when processed by the application, runs their own PHP code. This requires high-level access but poses a severe risk if admin accounts are compromised.
