Another Pleroma issue has been found, similar to yesterday's but this one also affects single user instances. Please update your servers once more, akkoma also has the same patch.
Pleroma security release: 2.5.4
 Thanks again to everyone involved in reporting and fixing this!
A new Pleroma security release is out that you should install immediately. If you can not do so for some reason, activate filename anonymization. Thanks to @npub1yck4...ujmw and @Haelwenn /ัะปะฒัะฝ/ :triskell: for handling this so quickly!
Pleroma security release: 2.5.3
