CVE-2026-44825: CWE-798 Use of Hard-coded Credentials in Apache Software Foundation Apache Solr
Hardcoded credentials in the Basic Authentication setup tool (bin/solr auth enable) in Apache Solr versions 9.4.0 through 9.10.1 and 10.0.0 allows a remote attacker to gain full administrative access to the cluster via publicly known default credentials installed silently alongside the user-specified account. As an immediate workaround without upgrading, delete the template users (superadmin, admin, search, index) from security.json or change their passwords. The future, not yet released, versions 9.11.0 and 10.1.0 will not be vulnerable, and it will be enough to upgrade to solve the issue. Not affected: * Clusters where bin/solr auth enable was not used to bootstrap BasicAuth * Clusters where template users have been assigned strong passwords after bootstrap
AI Analysis
Technical Summary
This vulnerability (CVE-2026-44825) affects Apache Solr versions 9.4.0 through 9.10.1 and 10.0.0. The issue arises from hardcoded credentials embedded in the Basic Authentication setup tool (bin/solr auth enable). These credentials are installed silently alongside user accounts, allowing remote attackers to authenticate with these default credentials and gain full administrative control over the Solr cluster. The vulnerability does not affect clusters that do not use the BasicAuth bootstrap or those that have changed the default template users' passwords. No vendor advisory or patch information is currently available.
Potential Impact
Remote attackers can leverage the hardcoded default credentials to gain full administrative access to affected Apache Solr clusters. This compromises confidentiality, integrity, and availability of the Solr service and its data. The vulnerability is rated with a CVSS 3.1 score of 8.1 (high severity), indicating a significant risk if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. In the meantime, administrators should avoid using the BasicAuth bootstrap or ensure that the default template users' passwords are changed immediately after setup to mitigate risk.
