Vulnerability Title
Scriban before 7.0.0 Stack Overflow via nested array initializers
Source: CVE Program / CVE List V5
Vulnerability Description
Scriban before 7.0.0 (affected versions <= 6.6.0) contains a stack overflow vulnerability in nested array initializer parsing. Deeply nested array initializers recurse through a path (ParseArrayInitializer → ParseExpression → ParseArrayInitializer) that is not covered by the ExpressionDepthLimit counter added in the fix for GHSA-wgh7-7m3c-fx25. An attacker who can supply untrusted input to Template.Parse can trigger an uncatchable StackOverflowException that immediately terminates the process, even with the default ExpressionDepthLimit enabled.

Vulnerability Title
scriban 资源管理错误漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
scriban是scriban组织的一款高性能的文本模板引擎。 scriban 7.0.0之前版本存在资源管理错误漏洞，该漏洞源于嵌套数组初始化器解析时未覆盖ExpressionDepthLimit计数器，导致深度嵌套数组初始化器通过ParseArrayInitializer→ParseExpression→ParseArrayInitializer路径递归造成栈溢出，攻击者可通过向Template.Parse提供不可信输入触发无法捕获的StackOverflowException，导致进程立即终止。
