From the article, it sounds like the passwords are indeed stored in cleartext:
> On Feb. 1, 2025, Muneeb Akhter asked Sohaib Akhter for the plaintext password of an individual who submitted a complaint to the Equal Employment Opportunity Commission’s Public Portal, which was maintained by the Akhters’ employer. Sohaib Akhter conducted a database query on the EEOC database and then provided the password to Muneeb Akhter. That password was subsequently used to access that individual’s email account without authorization.
