[BUG] Serialization of 'Closure' not allowed on accepting Opt-In (no captcha)

[vk-chaertl]

Hello there,

We're getting the following error in typo3_src/10.4.26/typo3/sysext/fluid/Classes/ViewHelpers/FormViewHelper.php line 291 upon accepting a Double-Opt In-Link, but only sometimes:

Exception: Serialization of 'Closure' is not allowed.

For your convenience, here's the affected function:

    protected function renderHiddenReferrerFields()
    {
        /** @var RequestInterface $request */
        $request = $this->renderingContext->getControllerContext()->getRequest();
        $extensionName = $request->getControllerExtensionName();
        $controllerName = $request->getControllerName();
        $actionName = $request->getControllerActionName();
        $actionRequest = [
            '@extension' => $extensionName,
            '@controller' => $controllerName,
            '@action' => $actionName,
        ];

        $result = LF;
        $result .= '<input type="hidden" name="' . htmlspecialchars($this->prefixFieldName('__referrer[@extension]')) . '" value="' . htmlspecialchars($extensionName) . '" />' . LF;
        $result .= '<input type="hidden" name="' . htmlspecialchars($this->prefixFieldName('__referrer[@controller]')) . '" value="' . htmlspecialchars($controllerName) . '" />' . LF;
        $result .= '<input type="hidden" name="' . htmlspecialchars($this->prefixFieldName('__referrer[@action]')) . '" value="' . htmlspecialchars($actionName) . '" />' . LF;
/* Troublesome line next*/
        $result .= '<input type="hidden" name="' . htmlspecialchars($this->prefixFieldName('__referrer[arguments]')) . '" value="' . htmlspecialchars($this->hashService->appendHmac(base64_encode(serialize($request->getArguments())))) . '" />' . LF;
        $result .= '<input type="hidden" name="' . htmlspecialchars($this->prefixFieldName('__referrer[@request]')) . '" value="' . htmlspecialchars($this->hashService->appendHmac(json_encode($actionRequest))) . '" />' . LF;

        return $result;
    }

We're using some custom JQuery, Powermail Conditions, and NO Captcha.

Sadly, I am by no means proficient in PHP, so I figured I'd ask you guys if you know what's causing the problem before doing anything.

If you think this problem has nothing to do whatsoever with Powermail, feel free to close of course.

Thanks for your help!

same here in two different projects

Also having this issue after upgrading a project from 10.4 to 11.5.

[lapierrec]

Having the same problem with TYPO3 10.4 and Powermail 8.4.1.

[Gregor-Agnes]

Same here, where we could narrow it down to forms with double-optin and unique like

plugin.tx_powermail.settings.setup.validation {
   unique {
       # Enable unique check for {email} - every email must be unique on the page where mails are stored
       email = 1
   }
}

enabled.

Hello,

we have the same problem, with TYPO3 11.5.16 Powermail 10.4.3, Powermail Conditions 9.0.3 and we are using the Double-Opt-In feature.

Has anyone tested switching between different Mailer-Methods? We're on sendmail as in almost all of our TYPO3-Installations. I am thinking about trying out SMTP as method. But if someone already tried this, i'd be happy if you could share!

Thanks in advance

Sebastian

Same here, double opt-in, sendmail, powermail_conditions and email validation.

Try this in your Setup:

[request.getQueryParams()['tx_powermail_pi1'] && request.getQueryParams()['tx_powermail_pi1']['action'] == 'optinConfirm']
    plugin.tx_powermail.settings.setup.spamshield {
        _enable = 0
        methods.10._enable = 0
    }
[end]

@einpraegsam Hi Alex, i run in same issue but only if input field as a type of "password" is configured and the option "double optin" is activated. After clicking the confirmation link from the email, this error is thrown. At this point in time, the "password_mirrored" object no longer exists or the value is empty. In the PasswordValidator.php on line 37 would want to return an error message to this form. Only this session no longer exists and this error occurs. In my opinion is a revalidation not needed at this point.

Best regards David

Powermail: 8.4.2 /powermail/Classes/Domain/Validator/PasswordValidator.php

$this->setErrorAndMessage($answer->getField(), 'password');

how to reproduce

• add a mandatory field A
• make this field depending on on other field B (say show A on option C)
• choose C in B (A ist not displayed)
• Activate "Double Opt-In" for the form
• Go to FE and Sumit the Form
• Open Optin-Link in other Browser, or clear your cookies leads to validate field A as required (when confirmOptinAction forwards to createAction) (because Values of Session are missing)
• same occures with current Versions powermail 12.3.1 powermail_cond 11.2.2 and TYPO3 12.4.15 (but other error in FE)
