CVE-2026-54679

jq is a command-line JSON processor. Prior to 1.8.2, on 32bit system, jvpstringappend has a chance of integer/multiple overflowing and then causing a massive buffer overrun. This vulnerability is fixed in 1.8.2...

CVE-2026-47770 jq: stack overflow in deep structural equality

jq is a command-line JSON processor. Prior to 1.8.2, comparing two sufficiently deeply nested arrays with the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service via stack exhaustion uncontrolled recursion. The crash occurs in jq's recursive...

CVE-2026-49839

Summary: CVE-2026-49839 affects jq prior to 1.8.2, where in the --rawfile path an oversized string can trigger invalid-state reuse and heap-buffer-overflow writes. In detail, when jv_load_file(raw=1) reads attacker-controlled data, file chunks are appended to a single jv string accumulator; after...

CVE-2026-49839 jq --rawfile invalid-state reuse after String too long causes heap-buffer-overflow

jq is a command-line JSON processor. Prior to 1.8.2, jq --rawfile can turn a handled oversized-string error into invalid-state reuse and a real heap out-of-bounds write in assertion-disabled builds. When jvloadfileraw=1 reads an attacker-controlled file, it repeatedly appends file chunks to the...

CVE-2026-54679

CVE-2026-54679 affects the jq tool prior to version 1.8.2 on 32-bit systems. The vulnerability is in jvp_string_append where an integer overflow could trigger a massive buffer overrun, with a local attack vector and potential high impact on availability as described in the CVE. The issue is fixed...

jq: signed-int overflow in stack_reallocate

A flaw was found in jq, a command line JSON processor. The memory allocation size is calculated using a signed integer that can overflow when processing deeply nested generator forks. This integer overflow allows an attacker who can supply a sufficiently nested input to influence the memory...

jq: stack overflow via unbounded recursion in jv_contains

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...

jq: jq: Heap out-of-bounds write via oversized raw file processing

A flaw was found in jq, a command-line JSON processor. This vulnerability allows an attacker to trigger a heap out-of-bounds write by providing a specially crafted, oversized file to the jq --rawfile option. This can lead to a denial of service DoS, making the affected system or application...

jq: stack overflow in recursive object merge

A flaw was found in jq, a command line JSON processor. The jvobjectmergerecursive function, reachable via the operator when both operands are objects, does not have a depth limit when processing nested objects. This missing depth limit allows an attacker who can supply a sufficiently nested input...
