An integer overflow arises when assigning value using an index of 2147483647, the signed integer limit. This causes a denial of service. (CVE-2024-23337) It was discovered that jq did not correctly handle certain string concatenations. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2026-32316) It was discovered that jq did not correctly handle recursion in certain circumstances. An attacker could possibly use this issue to cause a denial of service. (CVE-2026-33947) It was discovered that jq did not correctly handle improperly terminated strings. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. (CVE-2026-33948) It was discovered that jq did not correctly handle checking certain variable types. An attacker could possibly use this issue to cause a denial of service or leak sensitive information. (CVE-2026-39956) It was discovered that jq did not correctly handle certain string formatting. An attacker could possibly use this issue to leak sensitive information or cause a denial of service. (CVE-2026-39979) It was discovered that jq used a fixed seed for hash table operations. An attacker could possibly use this issue to cause a denial of service. (CVE-2026-40164) A heap-buffer-overflow is present in function jv_string_vfmt in the jqfuzzexecute harness from oss-fuzz. This crash happens on file jv.c, line 1456 `void* p = malloc(sz); (CVE-2025-48060) Top-level jq programs loaded from a file with -f are truncated at the first embedded NUL byte on current upstream HEAD. A crafted filter file such as . followed by \x00 and arbitrary suffix compiles and executes as only the prefix before the NUL. This leaves jq with a post-CVE-2026-33948 prefix/full-buffer mismatch on the compilation path even though the JSON parser path has already been fixed. (CVE-2026-41256) The ordinary module loader recurses without cycle detection when two otherwise valid modules include each other (CVE-2026-44777)
