Logstash vulnerabilitiesRanked by how likely they are to be used.
Logstash is made by Elastic. We track 12 published vulnerabilities listed under that exact name, across 184 versions. None of them is on the list of flaws known to be exploited today. Elastic lists newer releases under their own names, such as Logstash X-Pack, so check those pages too.
We keep watching the known-exploited list.
Is Logstash listed under other names? Yes.
Elastic also lists Logstash under more specific names, such as Logstash X-Pack. Flaws listed only under those names are counted on their own pages, not here. If you run one of these, open its page for its own exploited flaws.
