277-279: Change empty XFCC header handling from one empty entry to no entries.Returning
[]string{""}causes the certificate validation loop to iterate once with an empty certificate, resulting in an UNAUTHENTICATED failure. Returning[]string{}skips unnecessary validation and avoids the auth side effect while remaining explicit about empty input.Note: The test case "zero values" in
TestSplitCertHeadercurrently expects[]string{""}and will need to be updated to expect[]string{}.🔧 Proposed change
if certHeader == "" { - return []string{""}, nil + return []string{}, nil }🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@internal/extauthz/check.go` around lines 277 - 279, The current handling in internal/extauthz/check.go returns []string{""} when certHeader == "" which forces one empty cert into validation; change this to return an empty slice ([]string{}) so no entries are validated. Update the corresponding test expectation in TestSplitCertHeader (the "zero values" case) to expect []string{} instead of []string{""}. Ensure the change is made where certHeader is checked (the certHeader == "" branch) so callers of the SplitCertHeader behavior no longer receive a single empty entry.

- Around line 290-293: The quote-toggle unconditionally flips inQuote on every
'"' which fails for escaped quotes like \" — update the '"' case in the parser
(the branch that currently does inQuote = !inQuote and current.WriteByte(ch)) to
first detect if the quote is escaped and only toggle when it is not escaped;
implement this by checking the previous character (or maintain an escaped
boolean) so that a backslash that is itself not escaped prevents toggling. Apply
the same fix to the other similar quote-handling block (the code around the
current.WriteByte(ch) at the later location) so both places ignore escaped
quotes when deciding to flip inQuote.

Quote-state toggling is incorrect for escaped quotes inside quoted values.
Line 290 flips inQuote on every ". Inputs containing escaped quotes (e.g., \") will be parsed incorrectly and can trigger false unclosed quote errors or wrong splits.
🔧 Proposed change
- for i := 0; i < len(certHeader); i++ {
+ for i := 0; i < len(certHeader); i++ {
ch := certHeader[i]
+ if inQuote && ch == '\\' && i+1 < len(certHeader) {
+ current.WriteByte(ch)
+ i++
+ current.WriteByte(certHeader[i])
+ continue
+ }
switch ch {
case '"':
// Toggle quote state
inQuote = !inQuote
current.WriteByte(ch)Also applies to: 311-314
