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."}, {"lang": "es", "value": "goxmlsig proporciona Firmas Digitales XML implementadas en Go.

En versiones de Go anteriores a la 1.22, o cuando 'go.mod' utiliza una versi\u00f3n anterior, existe un problema de captura de variable de bucle.
