- Around line 333-341: The code appends "200" to options.OutputMatchStatusCode
when options.SecurityTxt is true, but parsing into the internal matchStatusCode
slice happens earlier in ValidateOptions()/ParseOptions(), so the appended 200
is ignored; to fix, ensure the status-code parsing runs after you modify
OutputMatchStatusCode — either move the append logic for
options.OutputMatchStatusCode (and any related options.RequestURIs changes) to
before ValidateOptions()/New() in ParseOptions(), or call the same parsing
routine that produces matchStatusCode again after the append so matchStatusCode
includes "200" (refer to options.SecurityTxt, options.OutputMatchStatusCode,
ValidateOptions(), ParseOptions(), New(), and the matchStatusCode parsing
logic).
- Around line 3021-3031: The isSecurityTxt function only checks for the exact
case "Contact:" which can miss valid security.txt field names; update the check
in isSecurityTxt to perform a case-insensitive search for the "contact:" field
(e.g., normalize resp.RawData to lowercase and check for "contact:" or use a
case-insensitive regex) so that variants like "contact:" or "CONTACT:" are
detected while keeping the existing Content-Type and status checks intact.

Critical: OutputMatchStatusCode modification occurs after parsing, making status code filter ineffective.
When --security-txt is enabled, this code appends "200" to options.OutputMatchStatusCode. However, ValidateOptions() (called before New() in ParseOptions()) has already parsed OutputMatchStatusCode into the matchStatusCode slice used for filtering at line 1204.
As a result, the 200 status code match won't be enforced when using --security-txt alone, potentially returning non-200 responses.
🐛 Proposed fix: Parse the status code after modification
if options.SecurityTxt {
options.OutputMatchString = append(options.OutputMatchString, "Contact:")
options.OutputMatchStatusCode = appendCommaSeparatedValue(options.OutputMatchStatusCode, "200")
options.RequestURIs = appendCommaSeparatedValue(options.RequestURIs, "/.well-known/security.txt,/security.txt")
options.JSONOutput = true
+ // Re-parse matchStatusCode since we modified OutputMatchStatusCode after initial parsing
+ if parsed, err := stringz.StringToSliceInt(options.OutputMatchStatusCode); err == nil {
+ options.matchStatusCode = parsed
+ }

🧩 Analysis chain
🌐 Web query:
RFC 9116 security.txt field name case sensitivity
💡 Result:
RFC 9116 specifies that security.txt field names are case-insensitive. It defines the field “name” as a field-name per RFC 5322 and then explicitly states: “Field names are case insensitive (as per Section 2.3 of RFC 5234).” (datatracker.ietf.org)
Citations:
Case-sensitive "Contact:" check may miss valid security.txt files.
Per RFC 9116, field names in security.txt are case-insensitive. The current check strings.Contains(body, "Contact:") will miss valid files using lowercase contact: or mixed case variants.
Suggested fix
func isSecurityTxt(resp *httpx.Response) bool {
if resp == nil || resp.StatusCode != 200 {
return false
}
contentType := strings.ToLower(resp.GetHeaderPart("Content-Type", ";"))
if contentType != "" && !strings.Contains(contentType, "text/plain") {
return false
}
- body := string(resp.RawData)
- return strings.Contains(body, "Contact:")
+ body := strings.ToLower(string(resp.RawData))
+ return strings.Contains(body, "contact:")
