Translation:À moins que tu ne sois passée chez moi.
It is active, not passive. Verb "passer" here is conjugated in a compound tense with auxiliary "être" because it is its intransitive form (like verb venir, for example)

If you use verb "passer" in a transitive form, you will use auxiliary "avoir" in all compound tenses (like verb donner, for example)
