CVE-2026-40504— Gravity 安全漏洞

Creolabs Gravity < 0.9.6 Heap Buffer Overflow via gravity_vm_exec

Creolabs Gravity before 0.9.6 contains a heap buffer overflow vulnerability in the gravity_vm_exec function that allows attackers to write out-of-bounds memory by crafting scripts with many string literals at global scope. Attackers can exploit insufficient bounds checking in gravity_fiber_reassign() to corrupt heap metadata and achieve arbitrary code execution in applications that evaluate untrusted scripts.

CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

堆缓冲区溢出

Gravity 安全漏洞

Gravity是Marco Bambini个人开发者的一种用 C 编写的强大的、动态类型的、轻量级的、可嵌入的编程语言。用于过程编程、面向对象编程、函数式编程和数据驱动编程。 Gravity 0.9.6之前版本存在安全漏洞，该漏洞源于gravity_vm_exec函数中存在堆缓冲区溢出，攻击者可通过制作包含许多全局字符串字面量的脚本来写入越界内存，可能导致任意代码执行。
