Hi, The following vulnerability was published for haskell-aeson. CVE-2021-41119[0]: | Wire-server is the system server for the wire back-end services. | Releases prior to v2022-03-01 are subject to a denial of service | attack via a crafted object causing a hash collision. This collision | causes the server to spend at least quadratic time parsing it which | can lead to a denial of service for a heavily used server. The issue | has been fixed in wire-server 2022-03-01 and is already deployed on | all Wire managed services. On premise instances of wire-server need to | be updated to 2022-03-01, so that their backends are no longer | affected. There are no known workarounds for this issue. The vulnerable code is in the Aeson library, used by wire-server. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
