| CVE-2021-43304 | 2 Clickhouse, Debian | 2 Clickhouse, Debian Linux | 2025-06-25 | 8.8 High |
| 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-2021-42390 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 6.5 Medium |
| 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 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 6.5 Medium |
| 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-2021-42387 | 2 Clickhouse, Debian | 2 Clickhouse, Debian Linux | 2025-06-25 | 8.1 High |
| 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-2021-42388 | 2 Clickhouse, Debian | 2 Clickhouse, Debian Linux | 2025-06-25 | 8.1 High |
| 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-2021-42391 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 6.5 Medium |
| 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-2021-43305 | 2 Clickhouse, Debian | 2 Clickhouse, Debian Linux | 2025-06-25 | 8.8 High |
| 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-2019-15024 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 6.5 Medium |
| 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-2018-14669 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | N/A |
| ClickHouse MySQL client before versions 1.1.54390 had "LOAD DATA LOCAL INFILE" functionality enabled that allowed a malicious MySQL database read arbitrary files from the connected ClickHouse server. | ||||
| CVE-2018-14671 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | N/A |
| In ClickHouse before 18.10.3, unixODBC allowed loading arbitrary shared objects from the file system which led to a Remote Code Execution vulnerability. | ||||
| CVE-2018-14672 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | N/A |
| In ClickHouse before 18.12.13, functions for loading CatBoost models allowed path traversal and reading arbitrary files through error messages. | ||||
| CVE-2018-14670 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | N/A |
| Incorrect configuration in deb package in ClickHouse before 1.1.54131 could lead to unauthorized use of the database. | ||||
| CVE-2019-18657 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 5.3 Medium |
| ClickHouse before 19.13.5.44 allows HTTP header injection via the url table function. | ||||
| CVE-2019-16535 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 9.8 Critical |
| 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-2018-14668 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | N/A |
| In ClickHouse before 1.1.54388, "remote" table function allowed arbitrary symbols in "user", "password" and "default_database" fields which led to Cross Protocol Request Forgery Attacks. | ||||
| CVE-2019-16536 | 1 Clickhouse | 1 Clickhouse | 2025-06-25 | 8.8 High |
| Stack overflow leading to DoS can be triggered by a malicious authenticated client in Clickhouse before 19.14.3.3. | ||||
| CVE-2024-23689 | 1 Clickhouse | 1 Java Libraries | 2025-05-30 | 8.8 High |
| 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-2023-48298 | 1 Clickhouse | 2 Clickhouse, Clickhouse Cloud | 2024-11-27 | 5.9 Medium |
| 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-2023-48704 | 1 Clickhouse | 2 Clickhouse, Clickhouse Cloud | 2024-11-21 | 7 High |
| 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-2023-47118 | 1 Clickhouse | 2 Clickhouse, Clickhouse Cloud | 2024-11-21 | 7 High |
| 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. | ||||
