> Document the non-exploitability of the April 2026 Log4j security advisories
> in the Solr 9.10.1 distribution:
> * CVE-2026-34477
> * CVE-2026-34478
> * CVE-2026-34479
> * CVE-2026-34480
> * CVE-2026-34481
> None of these vulnerabilities affect Solr 9.10.1 under the *default logging
> configuration*.
> CVE-2026-34481 is additionally not exploitable under *any* configuration,
> because Solr issues no logging calls that could trigger it.
