This may lead to a less comprehensive review. WalkthroughOn decryption error, the encryptcookie middleware now keeps the cookie key present but sets its value to an empty string in the request/response instead of removing the cookie; successful decryption behavior is unchanged. A test was added to assert no panic for invalid cookie values. Changes

Code Review
This pull request addresses a panic in the EncryptCookie middleware that occurs when it encounters a non-encrypted cookie. The fix replaces the call to c.Request().Header.DelCookieBytes(key), which was causing the panic, with c.Request().Header.SetCookie(string(key), ""). This change effectively neutralizes invalid cookies by setting their value to an empty string, preventing the application crash. The change is simple, effective, and correctly works around the underlying issue. I have provided one suggestion for a minor performance improvement, but the current change is correct and resolves the reported issue.

24-34: Add test coverage for cookies with special characters in the name.The fix correctly replaces
DelCookieByteswithSetCookie(string(key), "")on decryption failure, which resolves the panic when processing cookies with special characters like colons. The behavioral change—setting cookies to empty strings instead of deleting them—is partially tested.However, the test suite lacks coverage for the specific scenario that triggered the panic: cookie names containing special characters (e.g., "sidebar:state"). Add a test case that sets a request cookie with special characters in the name and an invalid encrypted value to verify the middleware handles the error gracefully without panicking.

29-29: ReusekeyStringto avoid duplicate string conversion.Line 25 already converts
keytokeyString, but line 29 performs the conversion again withstring(key). Reuse the existing variable for better efficiency.🔎 Proposed fix
- c.Request().Header.SetCookie(string(key), "") + c.Request().Header.SetCookie(keyString, "")
27-29: Consider logging or tracking decryption failures for security and debugging.Decryption errors are currently silently ignored, which could hide important issues such as cookie tampering attempts, key rotation problems, or malformed cookies. Unlike encryption errors (lines 47-48), which are properly returned, decryption failures provide no visibility.
Consider adding at minimum debug-level logging when decryption fails, or expose a metric/counter for monitoring. This would aid in debugging and security monitoring without breaking the current error handling flow.
Example implementation (add logging):
decryptedValue, err := cfg.Decryptor(keyString, string(value), cfg.Key) if err != nil { // Log decryption failure for debugging/security monitoring // Example: log.Debug().Err(err).Str("cookie", keyString).Msg("cookie decryption failed") c.Request().Header.SetCookie(keyString, "") } else { c.Request().Header.SetCookie(keyString, decryptedValue) }
31-31: Apply the same optimization here: reusekeyString.Similar to line 29, this line also performs a duplicate string conversion. For consistency and efficiency, use
keyStringhere as well.🔎 Proposed fix
- c.Request().Header.SetCookie(string(key), decryptedValue) + c.Request().Header.SetCookie(keyString, decryptedValue)

28-32: Consider reusing thekeyStringvariable to avoid redundant string conversion.On line 29,
string(key)is converted to a string for the second time;keyStringis already created on line 25 and should be reused here.Also note that setting failed decryption cookies to an empty string (rather than removing them) is intentional behavior per the middleware design—as confirmed by the comprehensive test coverage in
encryptcookie_test.go, which validates that invalid/malformed cookies result in empty values.

middleware/encryptcookie/encryptcookie_test.go (1)
110-140: LGTM! Test correctly validates the panic fix.The test properly verifies that invalid/unencrypted cookies don't crash the middleware and that the cookie value is cleared as expected. The test follows coding guidelines by calling
t.Parallel()at the start.Optional: Minor improvements to error handling and test robustness
Consider these small refinements:
- Handle the error from
resp.Body.Readinstead of ignoring it:- body := make([]byte, 64) - n, _ := resp.Body.Read(body) - require.Equal(t, "value=", string(body[:n])) + body, err := io.ReadAll(resp.Body) + require.NoError(t, err) + require.Equal(t, "value=", string(body))Add
ioto the imports if using this approach.
- Optionally, test with the specific cookie name from issue #3954 to demonstrate the exact scenario is fixed:
req.AddCookie(&http.Cookie{ - Name: "test", + Name: "sidebar:state", Value: "plaintext-unencrypted-value", })And update the handler to read the corresponding cookie:
app.Get("/", func(c fiber.Ctx) error { - return c.SendString("value=" + c.Cookies("test")) + return c.SendString("value=" + c.Cookies("sidebar:state")) })

There was a problem hiding this comment.
the mentioned problem has no relation with sidebar:state key. it is happening on every unexpected and non encrypted cookie.
|
While this works, it also means we try to decrypt every cookie. Even the ones not encrypted. |
|
@gaby maybe completely changing the middleware solves the root cause. middleware by itself tries every single cookie that exists in request. |

Description
Any non-encrypted cookie that doesn't set in except list for EncryptCookie middleware crashes the application.
