CVE-2026-40612

A flaw was found in jq, a command line JSON processor. The jvcontains function does not have a depth limit when processing nested arrays or objects. This missing depth limit allows an attacker who can supply a sufficiently nested input structure to exhaust the stack memory, causing an application...

SUSE CVE-2026-40612

jq is a command-line JSON processor. In 1.8.1 and earlier, jvcontains recurses into nested arrays/objects with no depth limit. With a sufficiently nested input structure built programmatically with reduce, since the JSON parser caps at depth 10000, the C stack is exhausted...

SUSE CVE-2026-41256

jq is a command-line JSON processor. In 1.8.1 and earlier, 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...

SUSE CVE-2026-41257

jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond 1 GiB via deeply nested generator forks, the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for a...

SUSE CVE-2026-43896

jq is a command-line JSON processor. In 1.8.1 and earlier, unbounded recursion in jvobjectmergerecursive allows a crafted jq program to crash the process with a segfault. The function is reachable through the operator when both operands are objects...

SUSE CVE-2026-44777

jq is a command-line JSON processor. In 1.8.2rc1 and earlier, the ordinary module loader recurses without cycle detection when two otherwise valid modules include each other...

jq: jq: Denial of Service via crafted JSON object causing hash collisions

A flaw was found in jq, a command-line JSON processor. A remote attacker could exploit this vulnerability by providing a specially crafted JSON object. This object leverages a weakness in jq's hashing algorithm, which uses a hardcoded, publicly known seed. By crafting the JSON object to cause has...
