——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.10h CVE-2026-11053610.0 CRI

——0A vulnerability was determined in D-Link DIR-868L 2.01b05. This impacts the function system of the file /htdocs/cgibin of the component HNAP CGI Handler. Executing a manipulation of the argument SOAPACTION can lead to os command injection. The attack may be launched remotely. The exploit has been publicly disclosed and may be utilized.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 2.3.7.12h CVE-2026-1012166.6 MED
