The crash occurs in jq\u0027s recursive structural comparison code, with the recursion repeating through jvp_array_equal() and jv_equal() in src/jv.c when comparing deeply nested arrays; a nearby sort comparator path through jv_cmp() in src/jv_aux.c overflows the stack at a larger nesting depth from  the same missing recursion guard. Anyone running jq comparisons on attacker-controlled deeply nested JSON values, or embedding jq in a context  where untrusted data can reach the == comparison path, is affected.

CVE-2026-43895 (GCVE-0-2026-43895)

Vulnerability from cvelistv5 – Published: 2026-05-11 17:24 – Updated: 2026-05-13 14:41

Title

jq: Embedded NUL in jq import paths causes local redaction-policy bypass and preserves sensitive fields in published artifacts

Summary

jq is a command-line JSON processor. In 1.8.1 and earlier, jq accepts embedded NUL bytes in import paths at the jq-language level, but later resolves those paths through C string operations during module and data-file lookup. This creates a mismatch between the logical import string that policy or audit code may validate and the on-disk path that jq actually opens.

Severity

4.4 (Medium)

CVE-2026-47770 (GCVE-0-2026-47770)

Vulnerability from cvelistv5 – Published: 2026-06-25 17:22 – Updated: 2026-06-26 18:42

Title

jq: stack overflow in deep structural equality

Summary

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 structural comparison code, with the recursion repeating through jvp_array_equal() and jv_equal() in src/jv.c when comparing deeply nested arrays; a nearby sort comparator path through jv_cmp() in src/jv_aux.c overflows the stack at a larger nesting depth from the same missing recursion guard. Anyone running jq comparisons on attacker-controlled deeply nested JSON values, or embedding jq in a context where untrusted data can reach the == comparison path, is affected. This vulnerability is fixed in 1.8.2.

Severity

6.8 (Medium)
