Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Users who 1. use the exclusion operator somewhere in their authorization schema 1. have configured their SpiceDB server such that `--write-relationships-max-updates-per-call` is bigger than 6500 1. issue calls to WriteRelationships with a large enough number of updates that cause the payload to be bigger than what their datastore allows will 1. receive a successful response from their `WriteRelationships` call, when in reality that call failed, 2. receive incorrect permission check results, if those relationships had to be read to resolve the relation involving the exclusion ### Patches Upgrade to v.145.2. ### Workarounds Set `--write-relationships-max-updates-per-call` to `1000`.
