CVE-2025-49131 is a critical sandbox escape vulnerability affecting FastGPT versions prior to 4.9.11. The flaw stems from insufficient isolation and overly permissive syscalls within the fastgpt-sandbox container, allowing attackers to bypass intended boundaries. This enables unauthorized reading and writing of arbitrary files and circumvention of Python module import restrictions. With a CVSS score of 9.9 (CRITICAL), this vulnerability is easily exploitable over the network with low privileges and no user interaction, leading to complete compromise of confidentiality, integrity, and availability. While there is no evidence of active exploitation or public exploit code, the vulnerability has garnered significant community discussion, indicating high awareness.
