Technical description

The Post Export Import with Media plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.17.1 via deserialization of untrusted input . This makes it possible for authenticated attackers, with administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

——0ILIAS before 9.24, 10.12, and 11.5 contains a PHP object injection vulnerability that allows authenticated users with Test creation or import permission to deserialize arbitrary objects via crafted Test archives. Attackers can inject a malicious tst_sequence sequence attribute that is passed to unserialize(), abusing Guzzle or Monolog gadget chains to write PHP files and execute code.12h CVE-2026-555739.8 CRI

——0e107 is a content management system (CMS). Prior to 2.3.7, install.php decodes the attacker-controlled previous_steps POST parameter and passes it to unserialize() at file scope and again in the e_install constructor without restricting allowed classes. The installer remains accessible after a normal installation, and a crafted object graph using the bundled GuzzleHttp\Psr7\PumpStream class can flow through paths.hash into site_path, where string coercion invokes an attacker-controlled callable. An unauthenticated attacker who can reach install.php can therefore execute arbitrary PHP functions with the web server process's privileges, leading to full server compromise. This issue is fixed in version 2.3.7.14h CVE-2026-972787.2 HIG
