GHSA-q87v-q8fw-gmj5
Summary Empty passwords validation issue Validating a user password with a `UserPassword` constraint but with no `NotBlank` constraint passes without any error (the empty password would not be compared with the user password). Note that you should always be explicit and add a `NotBlank` constraint, but as it worked before without, it's considered as a backward compatibility break and a security issue.
