CVE-2026-40164 1 Jqlang 1 Jq 2026-04-17 7.5 High
jq is a command-line JSON processor. Before commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784, jq used MurmurHash3 with a hardcoded, publicly visible seed (0x432A9843) for all JSON object hash table operations, which allowed an attacker to precompute key collisions offline. By supplying a crafted JSON object (~100 KB) where all keys hashed to the same bucket, hash table lookups degraded from O(1) to O(n), turning any jq expression into an O(n²) operation and causing significant CPU exhaustion. This affected common jq use cases such as CI/CD pipelines, web services, and data processing scripts, and was far more practical to exploit than existing heap overflow issues since it required only a small payload. This issue has been patched in commit 0c7d133c3c7e37c00b6d46b658a02244fdd3c784.
CVE-2025-48060 2 Jqlang, Redhat 7 Jq, Enterprise Linux, Rhel Aus and 4 more 2025-11-03 7.5 High
jq is a command-line JSON processor. In versions up to and including 1.7.1, a heap-buffer-overflow is present in function `jv_string_vfmt` in the jq_fuzz_execute harness from oss-fuzz. This crash happens on file jv.c, line 1456 `void* p = malloc(sz);`. As of time of publication, no patched versions are available.
CVE-2025-9403 1 Jqlang 1 Jq 2025-09-12 3.3 Low
A vulnerability was determined in jqlang jq up to 1.6. Impacted is the function run_jq_tests of the file jq_test.c of the component JSON Parser. Executing manipulation can lead to reachable assertion. The attack requires local access. The exploit has been publicly disclosed and may be utilized. Other versions might be affected as well.
CVE-2024-53427 1 Jqlang 1 Jq 2025-07-01 8.1 High
decNumberCopy in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as numeric, which has a resultant stack-based buffer overflow and out-of-bounds write, as demonstrated by use of --slurp with subtraction, such as a filter of .-. when the input has a certain form of digit string with NaN (e.g., "1 NaN123" immediately followed by many more digits).
CVE-2024-23337 2 Jqlang, Redhat 7 Jq, Enterprise Linux, Rhel Aus and 4 more 2025-06-24 4.3 Medium
jq is a command-line JSON processor. In versions up to and including 1.7.1, an integer overflow arises when assigning value using an index of 2147483647, the signed integer limit. This causes a denial of service. Commit de21386681c0df0104a99d9d09db23a9b2a78b1e contains a patch for the issue.
CVE-2025-49014 1 Jqlang 1 Jq 2025-06-23 5.3 Medium
jq is a command-line JSON processor. In version 1.8.0 a heap use after free vulnerability exists within the function f_strflocaltime of /src/builtin.c. This issue has been patched in commit 499c91b, no known fix version exists at time of publication.
CVE-2023-50246 1 Jqlang 1 Jq 2025-04-25 6.2 Medium
jq is a command-line JSON processor. Version 1.7 is vulnerable to heap-based buffer overflow. Version 1.7.1 contains a patch for this issue.
CVE-2023-50268 1 Jqlang 1 Jq 2025-02-13 6.2 Medium
jq is a command-line JSON processor. Version 1.7 is vulnerable to stack-based buffer overflow in builds using decNumber. Version 1.7.1 contains a patch for this issue.
CVE-2023-49355 1 Jqlang 1 Jq 2024-11-21 7.5 High
decToString in decNumber/decNumber.c in jq 88f01a7 has a one-byte out-of-bounds write via the " []-1.2e-1111111111" input. NOTE: this is not the same as CVE-2023-50246. The CVE-2023-50246 71c2ab5 reference mentions -10E-1000010001, which is not in normalized scientific notation.
