CVE-2026-55573 e107: Unsafe deserialization in install.php allows unauthenticated RCE via POP chain

e107 is a content management system CMS. Prior to 2.3.7, install.php decodes the attacker-controlled previoussteps POST parameter and passes it to unserialize at file scope and again in the einstall constructor without restricting allowed classes. The installer remains accessible after a normal...

CVE-2025-61505

e107 CMS thru 2.3.3 are vulnerable to insecure deserialization in the install.php script.
