Updates

Status

Pending upstream fix

Impact

log4j-1.2-api 2.19.0 is bundled inside the logstash-filter-elastic_integration gem's jar-dependencies. The latest available release of the gem on rubygems (9.4.0) still ships the same vulnerable log4j 2.19.0; awaiting an upstream filter release that bundles a non-vulnerable log4j (>= 2.25.4).

Status
