#34297 reviewing enhancement

Passwords containing ' or " via wp_set_password() break login via wp-login.php

We are using custom plugins to have the user reset their passwords. Internally all that is done boils down to the following code:

wp_set_password('Test"123', 1);
// alternative test
    'ID' => 1,
    'user_password' => 'Test"123'

Doing this the password gets successfully changed inside the database.

Trying to login on wp-login.php now with the new password results in: "ERROR: The password you entered for the username admin is incorrect"

Login however still works using wp_signon().

I don't know what's going on there or where the differences are but surely this can't be intended behavior that we're not supposed to set passwords using ' or " via wp_set_passworod(), can it?

Hello @manuakasam, welcome to Trac!

Previously: #26573, #24367

It looks like you have to slash the passwords via wp_slash() first. I think we should add a note for this to all the password functions.

I wonder what I did wrong then when I manually escaped it myself :S

I can confirm that this solves the issue, so as you mentioned this is simply a documentation issue and not a bug itself.

wp_signon() and wp_set_password() and wp_update_user() would require this information. Potentionally more but those are the ones that I came into contact with now.

Thank you for the super quick response!

Your only other choice is:

 * Strip the slashes from Cookies
function _fix_cookies() {
    $_COOKIE = stripslashes_deep( $_COOKIE );
add_action( 'sanitize_comment_cookies', '_fix_cookies' );

I almost threw my computer out the window 4 years ago when I found this awful mess.

Two steps to write the patch:

  1. Look through the functions that expect a password, and determine (maybe through trial and error) which of them expect passwords to be slashed.
  2. Modify the docs accordingly.

Hello @manuakasam and @ocean90, wouldn't it be a nice idea to, instead of mentioning the wp_slash() in the docs for wp_signon(), wp_set_password() and wp_update_user(), write a check for these quotes in the plain text password and if so, wrap the wp_slash() function around the plain text password in core ourselves so that we can take away the need for developers to really needing to read that part of the documentation?

Apologies, the red and green colored code block in the previous patch should be reversed.

A revised version was uploaded.

Punting this because, incredibly, it's actually difficult to tell which fields in these functions need slashing and which don't. Needs someone to spend some time going through the call stack.
