CVE-2023-36825Network attack vector

Remote code execution via unsigned serialized screen state

Published Jul 11, 2023 · Updated Oct 23, 2024

Deserialization in Orchid Platform 14.0.0-alpha4 through 14.4.0 allows remote attackers to execute code through crafted _state input. Screen::extractState base64-decodes the request value, passes it to PHP unserialize, and invokes the reconstructed closure without authenticity protection. Exploitation requires user interaction and runs attacker-controlled code in the Laravel application's server context.
