CVE-2021-44548 [CRITICAL] CWE-20 CVE-2021-44548: An Improper Input Validation vulnerability in DataImportHandler of Apache Solr allows an attacker to An Improper Input Validation vulnerability in DataImportHandler of Apache Solr allows an attacker to provide a Windows UNC path resulting in an SMB network call being made from the Solr host to another host on the network. If the attacker has wider access to the network, this may lead to SMB attacks, which may result in: * The exfiltration of sensi

CVE-2021-29943 [CRITICAL] CWE-863 CVE-2021-29943: When using ConfigurableInternodeAuthHadoopPlugin for authentication, Apache Solr versions prior to 8 When using ConfigurableInternodeAuthHadoopPlugin for authentication, Apache Solr versions prior to 8.8.2 would forward/proxy distributed requests using server credentials instead of original client credentials. This would result in incorrect authorization resolution on the receiving hosts.

CVE-2024-52012 [MEDIUM] CWE-23 CVE-2024-52012: Relative Path Traversal vulnerability in Apache Solr. Solr instances running on Windows are vulnera Relative Path Traversal vulnerability in Apache Solr. Solr instances running on Windows are vulnerable to arbitrary filepath write-access, due to a lack of input-sanitation in the "configset upload" API. Commonly known as a "zipslip", maliciously constructed ZIP files can use relative filepaths to write data to unanticipated parts of the filesystem.

CVE-2018-1308 [HIGH] CWE-611 CVE-2018-1308: This vulnerability in Apache Solr 1.2 to 6.6.2 and 7.0.0 to 7.2.1 relates to an XML external entity This vulnerability in Apache Solr 1.2 to 6.6.2 and 7.0.0 to 7.2.1 relates to an XML external entity expansion (XXE) in the `&dataConfig=` parameter of Solr's DataImportHandler. It can be used as XXE using file/ftp/http protocols in order to read arbitrary local files from the Solr server or the internal network.

CVE-2017-3164 [HIGH] CWE-918 CVE-2017-3164: Server Side Request Forgery in Apache Solr, versions 1.3 until 7.6 (inclusive). Since the "shards" p Server Side Request Forgery in Apache Solr, versions 1.3 until 7.6 (inclusive). Since the "shards" parameter does not have a corresponding whitelist mechanism, a remote attacker with access to the server could make Solr perform an HTTP GET request to any reachable URL.

CVE-2026-22022 [HIGH] CWE-285 CVE-2026-22022: Deployments of Apache Solr 5.3.0 through 9.10.0 that rely on Solr's "Rule Based Authorization Plugin Deployments of Apache Solr 5.3.0 through 9.10.0 that rely on Solr's "Rule Based Authorization Plugin" are vulnerable to allowing unauthorized access to certain Solr APIs, due to insufficiently strict input validation in those components. Only deployments that meet all of the following criteria are impacted by this vulnerability: * Use of Solr's "Rule
