Remote code execution via deserialization gadget chain
Published Feb 8, 2023 · Updated Mar 25, 2025
Deserialization in ThinkPHP 6.0.0 through 6.0.13 and 6.1.0 through 6.1.1 allows remote attackers to execute arbitrary code. The published proof of concept builds a Pivot object chain whose destructor reaches Url::__toString, Channel::__call, Store::save, and Request::param, causing call_user_func to invoke an attacker-selected system filter on attacker-controlled parameters. Exploitation requires an application endpoint or other code path that passes attacker-controlled serialized data to PHP unserialize; the framework does not add that entry point itself.
