| CVE | Severity | Published▾ | Status | Exploitation | Description |
|---|---|---|---|---|---|
| CVE-2026-111497 | Critical | 2026-10-22 | Outside Waratek scope | Exploited | A buffer overflow vulnerability in the Brotli decoder (c/dec/decode.c) in Google Brotli versions 1.0.3 through 1.2.0 on all platforms allows a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial of service, or potentially execute arbitrary code using a crafted Brotli-compressed stream. Users need to update any Brotli libraries or binaries between 1.0.3 through 1.2.0 to the latest available version: 1.0.10 or 1.1.1 or 1.2.1. |
| CVE-2019-16536 | High | 2025-05-21 | Not applicable | No public exploit | Stack overflow leading to DoS can be triggered by a malicious authenticated client in Clickhouse before 19.14.3.3. |
| CVE-2025-1386 | Medium | 2025-04-11 | Not applicable | No public exploit | When using the ch-go library, under a specific condition when the query includes a large, uncompressed malicious external data, it is possible for an attacker in control of such data to smuggle another query packet into the connection stream. |
| CVE-2024-41436 | High | 2024-09-03 | Not applicable | Proof of concept only | ClickHouse v24.3.3.102 was discovered to contain a buffer overflow via the component DB::evaluateConstantExpressionImpl. |
| CVE-2024-22412 | Medium | 2024-03-18 | Not applicable | Proof of concept only | 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 bypassed if they are using query caching. Attackers who have control of a role could guess queries and see data they shouldn't have access to. Version 24.1 of ClickHouse and version 24.0.2.54535 of ClickHouse Cloud contain a patch for this issue. Based on the documentation, role based access control should be enforced regardless if query caching is enabled or not. |
| CVE-2024-23689 | High | 2024-01-19 | No exploit published | Proof of concept only | 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. |
| CVE-2023-48704 | High | 2023-12-22 | Not applicable | No public exploit | 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 ClickHouse Cloud version 23.9.2.47551 and ClickHouse versions 23.10.5.20, 23.3.18.15, 23.8.8.20, and 23.9.6.20. |
| CVE-2023-48298 | High | 2023-12-21 | Not applicable | No public exploit | 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. |
| CVE-2023-47118 | Critical | 2023-12-20 | Not applicable | No public exploit | 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 T64 codec that crashes the ClickHouse server process. This attack does not require authentication. Note that this exploit can also be triggered via HTTP protocol, however, the attacker will need a valid credential as the HTTP authentication take places first. This issue has been fixed in version 23.10.2.13-stable, 23.9.4.11-stable, 23.8.6.16-lts and 23.3.16.7-lts. |
| CVE-2022-44011 | Medium | 2023-11-23 | Not applicable | No public exploit | 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. |
| CVE-2022-44010 | High | 2023-11-23 | Not applicable | No public exploit | 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. |
| CVE-2021-43305 | High | 2022-03-14 | Not applicable | No public exploit | 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. |
| CVE-2021-43304 | High | 2022-03-14 | Not applicable | No public exploit | 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. |
| CVE-2021-42391 | Medium | 2022-03-14 | Not applicable | No public exploit | Divide-by-zero in Clickhouse's Gorilla compression codec when parsing a malicious query. The first byte of the compressed buffer is used in a modulo operation without being checked for 0. |
| CVE-2021-42390 | Medium | 2022-03-14 | Not applicable | No public exploit | Divide-by-zero in Clickhouse's DeltaDouble compression codec when parsing a malicious query. The first byte of the compressed buffer is used in a modulo operation without being checked for 0. |
| CVE-2021-42389 | Medium | 2022-03-14 | Not applicable | No public exploit | Divide-by-zero in Clickhouse's Delta compression codec when parsing a malicious query. The first byte of the compressed buffer is used in a modulo operation without being checked for 0. |
| CVE-2021-42388 | High | 2022-03-14 | Not applicable | No public exploit | 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. |
| CVE-2021-42387 | High | 2022-03-14 | Not applicable | No public exploit | 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 upper bounds of the source of the copy operation. |
| CVE-2019-16535 | Critical | 2019-12-30 | Not applicable | No public exploit | 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. |
| CVE-2019-15024 | Medium | 2019-12-30 | Not applicable | No public exploit | 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. |
| CVE-2019-18657 | Medium | 2019-10-31 | Not applicable | No public exploit | ClickHouse before 19.13.5.44 allows HTTP header injection via the url table function. |
| CVE-2018-14672 | Medium | 2019-08-15 | Not applicable | No public exploit | In ClickHouse before 18.12.13, functions for loading CatBoost models allowed path traversal and reading arbitrary files through error messages. |
