OWASP Top 10 Reference Regex for Go

What this pattern does

This page provides a lightweight, single-purpose regular expression for matching owasp top 10 reference, ported and verified for Go. In security-sensitive code, using an unverified regex can open the door to both false positives and denial-of-service attacks. The snippet below is ready to drop into your Go project — whether you're validating in a Gin handler, a gRPC service, or a command-line tool.

Go Implementation

// OWASP Top 10 Reference
// ReDoS-safe | RegexVault — Security > Audit & Compliance

package validation

import "regexp"

var owaspTop10ReferenceRe = regexp.MustCompile(`^A(?:0[1-9]|10):2021$`)

func ValidateOwaspTop10Reference(s string) bool {
    return owaspTop10ReferenceRe.MatchString(s)
}

// Example
// fmt.Println(ValidateOwaspTop10Reference("A01:2021")) // true

Test Cases

When to use this pattern

This pattern is drawn from the Security > Audit & Compliance category and carries a ReDoS-safe certification. That matters for Go developers because Go's RE2 engine is inherently safe from catastrophic backtracking, but this pattern has been additionally verified for correctness. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.
