CVE-2023-50290

70
FAUCET Score

CVE-2023-50290 is a medium-severity vulnerability in Apache Solr versions 9.0.0 through 9.2.x, allowing the Solr Metrics API to expose sensitive environment variables to unauthorized actors. An attacker with "metrics-read" permission can access these variables, potentially leading to information disclosure. While not actively exploited in the wild, public Nuclei templates exist, and its high EPSS and FAUCET scores indicate a significant risk. Organizations using affected Solr versions should upgrade to 9.3.0 or later to mitigate this risk.
