Improper Access Control in SLF4J
org.slf4j.ext.EventData in the slf4j-ext module in QOS.CH SLF4J before `1.8.0-beta4` allows remote attackers to bypass intended access restrictions via crafted data. EventData in the slf4j-ext module in QOS.CH SLF4J, has been fixed in SLF4J version `1.7.26` and later and in the `2.0.x` series.Note that while the [fix commit](https://github.com/qos-ch/slf4j/commit/d2b27fba88e983f921558da27fc29b5f5d269405) is associated with the tag `1.8.0-beta3`, the versions in [Maven](https://mvnrepository.com/artifact/org.slf4j/slf4j-ext) go directly from `1.8.0-beta2` to `1.8.0-beta4`.
