Summary
Apache Zeppelin versions 0.6.0 through 0.12.0 are vulnerable to Cross-Site Request Forgery (CSRF). The default CORS configuration allows cross-origin state-changing requests and accepts text/plain bodies, enabling an attacker to perform actions on behalf of an authenticated user.
Risk Assessment
An attacker can trick an authenticated user into performing unwanted actions via REST and WebSocket endpoints, potentially leading to data or configuration compromise.
Recommendation
It is recommended to upgrade Apache Zeppelin to version 0.12.1, which fixes the issue.
Other vulnerabilities in Apache Zeppelin
See all- CVE-2026-44615Medium
In Apache Zeppelin versions 0.9.0 through 0.12.0, when FileSystemNotebookRepo is configured, an authenticated attacker with rename or folder operation permissions can use traversal segments in note or folder paths. Zeppelin composes these into filesystem paths without ensuring they remain under the configured notebook directory, potentially allowing file move, write, or delete outside the notebook root.
- CVE-2026-44617Medium
Apache Zeppelin versions 0.11.1, 0.11.2, and 0.12.0 are vulnerable to LDAP filter injection. LdapRealm uses incorrect escaping (RFC 4514 instead of RFC 4515), leaving filter characters insufficiently escaped. This is an incomplete fix of CVE-2024-31867.
- CVE-2026-44616Medium
Apache Zeppelin versions 0.6.0 through 0.12.0 are vulnerable to LDAP injection. ActiveDirectoryGroupRealm constructs LDAP filters without escaping user input, allowing an authenticated attacker to inject filter syntax via the user-search endpoint.
Original NVD description (English source)
Cross-Site Request Forgery (CSRF) vulnerability in Apache Zeppelin. The default CORS configuration allowed cross-origin state-changing requests and accepted text/plain request bodies, allowing an attacker who lures an authenticated user to a malicious site to perform actions on the user's behalf through REST and WebSocket endpoints. This issue affects Apache Zeppelin versions 0.6.0 through 0.12.0. Users are recommended to upgrade to version 0.12.1, which fixes this issue.
