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 jv_load_file(raw=1) reads an attacker-controlled file, it repeatedly appends file chunks to the same jv string accumulator. Once jv_string_append_buf() returns jv_invalid_with_msg(\"String too long\"), the raw-file loop does not stop. If the file contains at least one more byte, the next loop iteration appends a new chunk to an object that is already invalid. With assertions enabled this aborts in jvp_string_ptr(). With assertions disabled, the invalid object is interpreted as a string object and ASan reports heap-buffer-overflow. This vulnerability is fixed in 1.8.2.",

CVE-2026-43896 (GCVE-0-2026-43896)

Vulnerability from cvelistv5 – Published: 2026-05-11 17:24 – Updated: 2026-05-12 16:15

Title

jq: Stack Overflow in Recursive Object Merge

Summary

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

Severity

6.2 (Medium)

CVE-2026-49839 (GCVE-0-2026-49839)

Vulnerability from cvelistv5 – Published: 2026-06-25 17:17 – Updated: 2026-06-25 17:55

Title

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

Summary

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 jv_load_file(raw=1) reads an attacker-controlled file, it repeatedly appends file chunks to the same jv string accumulator. Once jv_string_append_buf() returns jv_invalid_with_msg("String too long"), the raw-file loop does not stop. If the file contains at least one more byte, the next loop iteration appends a new chunk to an object that is already invalid. With assertions enabled this aborts in jvp_string_ptr(). With assertions disabled, the invalid object is interpreted as a string object and ASan reports heap-buffer-overflow. This vulnerability is fixed in 1.8.2.
