CVE-2026-33487— goxmldsig 安全漏洞

goxmldsig has validateSignature Loop Variable Capture Signature Bypass

goxmlsig provides XML Digital Signatures implemented in Go. Prior to version 1.6.0, the `validateSignature` function in `validate.go` goes through the references in the `SignedInfo` block to find one that matches the signed element's ID. In Go versions before 1.22, or when `go.mod` uses an older version, there is a loop variable capture issue. The code takes the address of the loop variable `_ref` instead of its value. As a result, if more than one reference matches the ID or if the loop logic is incorrect, the `ref` pointer will always end up pointing to the last element in the `SignedInfo.References` slice after the loop. goxmlsig version 1.6.0 contains a patch.

密码学签名的验证不恰当

goxmldsig 安全漏洞

goxmldsig是Russell Haering个人开发者的一个Go语言编写的数字签名库。该库继承了 SAML2.0，不需要命令行工具即可进行签名的生成和验证功能。 goxmldsig 1.6.0之前版本存在安全漏洞，该漏洞源于validateSignature函数存在循环变量捕获问题，可能导致签名验证逻辑错误。
