| CVE-2024-22412 | ClickHouse is an open-source column-oriented database management system. A bug exists in the cloud ClickHouse offering prior to version 24.0.2.54535 and in github.com/clickhouse/clickhouse version 23.1. Query caching bypasses the role based access controls and the policies being enforced on roles. In affected versions, the query cache only respects separate users, however this is not documented and not expected behavior. People relying on ClickHouse roles can have their access control lists bypa | [email protected] | 2.4 | 0.10% | 2024-03-18 | 2025-12-23 |
| CVE-2024-23689 | Exposure of sensitive information in exceptions in ClichHouse's clickhouse-r2dbc, com.clickhouse:clickhouse-jdbc, and com.clickhouse:clickhouse-client versions less than 0.4.6 allows unauthorized users to gain access to client certificate passwords via client exception logs. This occurs when 'sslkey' is specified and an exception, such as a ClickHouseException or SQLException, is thrown during database operations; the certificate password is then included in the logged exception message. | [email protected] | 8.8 | 1.26% | 2024-01-19 | 2025-11-29 |
| CVE-2023-48704 | ClickHouse is an open-source column-oriented database management system that allows generating analytical data reports in real-time. A heap buffer overflow issue was discovered in ClickHouse server. An attacker could send a specially crafted payload to the native interface exposed by default on port 9000/tcp, triggering a bug in the decompression logic of Gorilla codec that crashes the ClickHouse server process. This attack does not require authentication. This issue has been addressed in ClickH | [email protected] | 7.0 | 0.47% | 2023-12-22 | 2024-11-21 |
| CVE-2023-48298 | ClickHouse® is an open-source column-oriented database management system that allows generating analytical data reports in real-time. This vulnerability is an integer underflow resulting in crash due to stack buffer overflow in decompression of FPC codec. It can be triggered and exploited by an unauthenticated attacker. The vulnerability is very similar to CVE-2023-47118 with how the vulnerable function can be exploited. | [email protected] | 5.9 | 0.47% | 2023-12-21 | 2024-11-21 |
| CVE-2023-47118 | ClickHouse® is an open-source column-oriented database management system that allows generating analytical data reports in real-time. A heap buffer overflow issue was discovered in ClickHouse server.

| CVE-2022-44011 | An issue was discovered in ClickHouse before 22.9.1.2603. An authenticated user (with the ability to load data) could cause a heap buffer overflow and crash the server by inserting a malformed CapnProto object. The fixed versions are 22.9.1.2603, 22.8.2.11, 22.7.4.16, 22.6.6.16, and 22.3.12.19. | [email protected] | 6.5 | 0.09% | 2023-11-23 | 2024-11-21 |
| CVE-2022-44010 | An issue was discovered in ClickHouse before 22.9.1.2603. An attacker could send a crafted HTTP request to the HTTP Endpoint (usually listening on port 8123 by default), causing a heap-based buffer overflow that crashes the process. This does not require authentication. The fixed versions are 22.9.1.2603, 22.8.2.11, 22.7.4.16, 22.6.6.16, and 22.3.12.19. | [email protected] | 7.5 | 0.31% | 2023-11-23 | 2024-11-21 |
| CVE-2021-43305 | Heap buffer overflow in Clickhouse's LZ4 compression codec when parsing a malicious query. There is no verification that the copy operations in the LZ4::decompressImpl loop and especially the arbitrary copy operation wildCopy<copy_amount>(op, ip, copy_end), don’t exceed the destination buffer’s limits. This issue is very similar to CVE-2021-43304, but the vulnerable copy operation is in a different wildCopy call. | [email protected] | 8.8 | 0.28% | 2022-03-14 | 2025-06-25 |

| CVE-2021-42388 | Heap out-of-bounds read in Clickhouse's LZ4 compression codec when parsing a malicious query. As part of the LZ4::decompressImpl() loop, a 16-bit unsigned user-supplied value ('offset') is read from the compressed data. The offset is later used in the length of a copy operation, without checking the lower bounds of the source of the copy operation. | [email protected] | 8.1 | 0.28% | 2022-03-14 | 2025-06-25 |
| CVE-2021-42387 | Heap out-of-bounds read in Clickhouse's LZ4 compression codec when parsing a malicious query. As part of the LZ4::decompressImpl() loop, a 16-bit unsigned user-supplied value ('offset') is read from the compressed data.

| CVE-2019-16535 | In all versions of ClickHouse before 19.14, an OOB read, OOB write and integer underflow in decompression algorithms can be used to achieve RCE or DoS via native protocol. | [email protected] | 9.8 | 1.32% | 2019-12-30 | 2025-06-25 |
| CVE-2019-15024 | In all versions of ClickHouse before 19.14.3, an attacker having write access to ZooKeeper and who is able to run a custom server available from the network where ClickHouse runs, can create a custom-built malicious server that will act as a ClickHouse replica and register it in ZooKeeper. When another replica will fetch data part from the malicious replica, it can force clickhouse-server to write to arbitrary path on filesystem. | [email protected] | 6.5 | 0.43% | 2019-12-30 | 2025-06-25 |
| CVE-2019-18657 | ClickHouse before 19.13.5.44 allows HTTP header injection via the url table function. | [email protected] | 5.3 | 0.52% | 2019-10-31 | 2025-06-25 |
