Known Vulnerabilities Affecting Apache Pulsar 2.11
13 published CVEs affect the Apache Pulsar 2.11, including 9 rated critical or high severity. Apache Pulsar no longer ships security patches for this release — our engineers provide mitigation guidance, workarounds and hardening support.
| CVE | Severity | CVSS | Published | Summary |
|---|---|---|---|---|
| CVE-2023-30429 | CRITICAL | 9.6 | Jul 12, 2023 | Incorrect Authorization vulnerability in Apache Software Foundation Apache Pulsar. This issue affects Apache Pulsar: before 2.10.4, and 2.11.0. When a client connects to the Pulsar Function Worker via the Pulsar Proxy where the Pulsar Proxy uses mTLS authentication to authenticate with the Pulsar Function Worker, the Pulsar Function Worker incorrectly performs authorization by using the Proxy's role for authorization instead of the client's role, which can lead to privilege escalation, especia |
| CVE-2024-27894 | HIGH | 8.5 | Mar 12, 2024 | The Pulsar Functions Worker includes a capability that permits authenticated users to create functions where the function's implementation is referenced by a URL. The supported URL schemes include "file", "http", and "https". When a function is created using this method, the Functions Worker will retrieve the implementation from the URL provided by the user. However, this feature introduces a vulnerability that can be exploited by an attacker to gain unauthorized access to any file that the Puls |
| CVE-2024-27135 | HIGH | 8.5 | Mar 12, 2024 | Improper input validation in the Pulsar Function Worker allows a malicious authenticated user to execute arbitrary Java code on the Pulsar Function worker, outside of the sandboxes designated for running user-provided functions. This vulnerability also applies to the Pulsar Broker when it is configured with "functionsWorkerEnabled=true". This issue affects Apache Pulsar versions from 2.4.0 to 2.10.5, from 2.11.0 to 2.11.3, from 3.0.0 to 3.0.2, from 3.1.0 to 3.1.2, and 3.2.0. 2.10 Pulsar Funct |
| CVE-2024-27317 | HIGH | 8.4 | Mar 12, 2024 | In Pulsar Functions Worker, authenticated users can upload functions in jar or nar files. These files, essentially zip files, are extracted by the Functions Worker. However, if a malicious file is uploaded, it could exploit a directory traversal vulnerability. This occurs when the filenames in the zip files, which aren't properly validated, contain special elements like "..", altering the directory path. This could allow an attacker to create or modify files outside of the designated extraction |
| CVE-2022-34321 | HIGH | 8.2 | Mar 12, 2024 | Improper Authentication vulnerability in Apache Pulsar Proxy allows an attacker to connect to the /proxy-stats endpoint without authentication. The vulnerable endpoint exposes detailed statistics about live connections, along with the capability to modify the logging level of proxied connections without requiring proper authentication credentials. This issue affects Apache Pulsar versions from 2.6.0 to 2.10.5, from 2.11.0 to 2.11.2, from 3.0.0 to 3.0.1, and 3.1.0. The known risks include expos |
| CVE-2023-37579 | HIGH | 8.2 | Jul 12, 2023 | Incorrect Authorization vulnerability in Apache Software Foundation Apache Pulsar Function Worker. This issue affects Apache Pulsar: before 2.10.4, and 2.11.0. Any authenticated user can retrieve a source's configuration or a sink's configuration without authorization. Many sources and sinks contain credentials in the configuration, which could lead to leaked credentials. This vulnerability is mitigated by the fact that there is not a known way for an authenticated user to enumerate another te |
| CVE-2023-30428 | HIGH | 8.2 | Jul 12, 2023 | Incorrect Authorization vulnerability in Apache Software Foundation Apache Pulsar Broker's Rest Producer allows authenticated user with a custom HTTP header to produce a message to any topic using the broker's admin role. This issue affects Apache Pulsar Brokers: from 2.9.0 through 2.9.5, from 2.10.0 before 2.10.4, 2.11.0. The vulnerability is exploitable when an attacker can connect directly to the Pulsar Broker. If an attacker is connecting through the Pulsar Proxy, there is no known way to e |
| CVE-2023-37544 | HIGH | 7.5 | Dec 20, 2023 | Improper Authentication vulnerability in Apache Pulsar WebSocket Proxy allows an attacker to connect to the /pingpong endpoint without authentication. This issue affects Apache Pulsar WebSocket Proxy: from 2.8.0 through 2.8.*, from 2.9.0 through 2.9.*, from 2.10.0 through 2.10.4, from 2.11.0 through 2.11.1, 3.0.0. The known risks include a denial of service due to the WebSocket Proxy accepting any connections, and excessive data transfer due to misuse of the WebSocket ping/pong feature. 2.10 |
| CVE-2023-51437 | HIGH | 7.4 | Feb 7, 2024 | Observable timing discrepancy vulnerability in Apache Pulsar SASL Authentication Provider can allow an attacker to forge a SASL Role Token that will pass signature verification. Users are recommended to upgrade to version 2.11.3, 3.0.2, or 3.1.1 which fixes the issue. Users should also consider updating the configured secret in the `saslJaasServerRoleTokenSignerSecretPath` file. Any component matching an above version running the SASL Authentication Provider is affected. That includes the Pulsa |
| CVE-2024-29834 | MEDIUM | 6.4 | Apr 2, 2024 | This vulnerability allows authenticated users with produce or consume permissions to perform unauthorized operations on partitioned topics, such as unloading topics and triggering compaction. These management operations should be restricted to users with the tenant admin role or superuser role. An authenticated user with produce permission can create subscriptions and update subscription properties on partitioned topics, even though this should be limited to users with consume permissions. This |
| CVE-2024-28098 | MEDIUM | 6.4 | Mar 12, 2024 | The vulnerability allows authenticated users with only produce or consume permissions to modify topic-level policies, such as retention, TTL, and offloading settings. These management operations should be restricted to users with the tenant admin role or super user role. This issue affects Apache Pulsar versions from 2.7.1 to 2.10.5, from 2.11.0 to 2.11.3, from 3.0.0 to 3.0.2, from 3.1.0 to 3.1.2, and 3.2.0. 2.10 Apache Pulsar users should upgrade to at least 2.10.6. 2.11 Apache Pulsar users |
| CVE-2025-30677 | MEDIUM | 6.3 | Apr 9, 2025 | Apache Pulsar contains multiple connectors for integrating with Apache Kafka. The Pulsar IO Apache Kafka Source Connector, Sink Connector, and Kafka Connect Adaptor Sink Connector log sensitive configuration properties in plain text in application logs. This vulnerability can lead to unintended exposure of credentials in log files, potentially allowing attackers with access to these logs to obtain Apache Kafka credentials. The vulnerability's impact is limited by the fact that an attacker woul |
| CVE-2023-31007 | NONE | 0.0 | Jul 12, 2023 | Improper Authentication vulnerability in Apache Software Foundation Apache Pulsar Broker allows a client to stay connected to a broker after authentication data expires if the client connected through the Pulsar Proxy when the broker is configured with authenticateOriginalAuthData=false or if a client connects directly to a broker with a specially crafted connect command when the broker is configured with authenticateOriginalAuthData=false.
