CVE-2023-50291Network attack vector

Credential disclosure via incomplete system-property redaction

Published Feb 9, 2024 · Updated May 15, 2025

Insufficiently protected credentials in Apache Solr 6.0.0 through 8.11.2 and 9.0.0 before 9.3.0 allow remote attackers to read secrets. The /admin/info/properties handler redacts only property names containing “password,” so values such as basicauth and aws.secretKey are returned and displayed in the Admin UI. When authorization is enabled, access requires a logged-in account with config-read permission; exposed values are limited to sensitive properties present in the Solr process.
