# CVE-2026-33947: jq: Unbounded Recursion in jv_setpath(), jv_getpath() and delpaths_sorted() CVE-2026-33947 is fixed in 5 products on 1 platform, first by jq 1.5+dfsg-2ubuntu0.1~esm2, released April 13, 2026. It is not reported as exploited. Patch Radar priority: Routine. - Web page: https://patchblox.com/security/cve/CVE-2026-33947 - Priority: Routine - CVSS: 6.2 (Moderate) - EPSS: 0.0023 - CISA KEV: not listed - Exploited (vendor report): no - Publicly disclosed: no - Published: Apr 13, 2026 - Weakness: Uncontrolled Recursion - Vendor advisory: https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-33947 ## Description jq is a command-line JSON processor. In versions 1.8.1 and below, functions jv_setpath(), jv_getpath(), and delpaths_sorted() in jq's src/jv_aux.c use unbounded recursion whose depth is controlled by the length of a caller-supplied path array, with no depth limit enforced. An attacker can supply a JSON document containing a flat array of ~65,000 integers (~200 KB) that, when used as a path argument by a trusted jq filter, exhausts the C call stack and crashes the process with a segmentation fault (SIGSEGV). This bypass works because the existing MAX_PARSING_DEPTH (10,000) limit only protects the JSON parser, not runtime path operations where arrays can be programmatically constructed to arbitrary lengths. The impact is denial of service (unrecoverable crash) affecting any application or service that processes untrusted JSON input through jq's setpath, getpath, or delpaths builtins. This issue has been addressed in commit fb59f1491058d58bdc3e8dd28f1773d1ac690a1f. ## Where it's fixed | Platform | Product | Fixed in | Fix | Released | |---|---|---|---|---| | Linux | jq Debian 12.15 (bookworm) | 1.6-2.1+deb12u2 | [DEBIAN-CVE-2026-33947](https://patchblox.com/security/data/fix/linux/debian-cve-2026-33947.md) | Apr 13, 2026 | | Linux | jq Debian 13.5 (trixie) | 1.7.1-6+deb13u2 | [DEBIAN-CVE-2026-33947](https://patchblox.com/security/data/fix/linux/debian-cve-2026-33947.md) | Apr 13, 2026 | | Linux | jq Debian 14 | 1.8.1-5 | [DEBIAN-CVE-2026-33947](https://patchblox.com/security/data/fix/linux/debian-cve-2026-33947.md) | Apr 13, 2026 | | Linux | jq Fedora 43 | 1.8.1-3.fc43 | [FEDORA-2026-4E57162966](https://patchblox.com/security/data/fix/linux/fedora-2026-4e57162966.md) | Apr 16, 2026 | | Linux | jq Ubuntu 18.04.6 LTS (bionic) | 1.5+dfsg-2ubuntu0.1~esm2 | [jq 1.5+dfsg-2ubuntu0.1~esm2](https://patchblox.com/security/data/fix/linux/ubuntu-bionic-jq-1.5-dfsg-2ubuntu0.1-esm2.md) | Apr 13, 2026 | | Linux | jq Ubuntu 20.04 LTS (focal) | 1.6-1ubuntu0.20.04.1+esm2 | [jq 1.6-1ubuntu0.20.04.1+esm2](https://patchblox.com/security/data/fix/linux/ubuntu-focal-jq-1.6-1ubuntu0.20.04.1-esm2.md) | Apr 13, 2026 | | Linux | jq Ubuntu 22.04.1 LTS (jammy) | 1.6-2.1ubuntu3.2 | [jq 1.6-2.1ubuntu3.2](https://patchblox.com/security/data/fix/linux/ubuntu-jammy-jq-1.6-2.1ubuntu3.2.md) | Apr 13, 2026 | | Linux | jq Ubuntu 24.04.5 LTS (noble) | 1.7.1-3ubuntu0.24.04.2 | [jq 1.7.1-3ubuntu0.24.04.2](https://patchblox.com/security/data/fix/linux/ubuntu-noble-jq-1.7.1-3ubuntu0.24.04.2.md) | Apr 13, 2026 | | Linux | jq Ubuntu 25.10 (questing) | 1.8.1-3ubuntu1.1 | [jq 1.8.1-3ubuntu1.1](https://patchblox.com/security/data/fix/linux/ubuntu-questing-jq-1.8.1-3ubuntu1.1.md) | Apr 13, 2026 | | Linux | jq Ubuntu 26.04.1 LTS (resolute) | 1.8.1-4ubuntu2 | [jq 1.8.1-4ubuntu2](https://patchblox.com/security/data/fix/linux/ubuntu-resolute-jq-1.8.1-4ubuntu2.md) | Apr 13, 2026 | | Linux | jq amzn 2023 | 1.8.1-59.amzn2023 | [ALAS2023-2026-1815](https://patchblox.com/security/data/fix/linux/alas2023-2026-1815.md) | Jun 8, 2026 | | Linux | jq opensuse-leap 16.0 | 1.7.1-160000.3.1 | [OPENSUSE-SU-2026:21248-1](https://patchblox.com/security/data/fix/linux/opensuse-su-2026-21248-1.md) | Jul 7, 2026 | | Linux | jq sles 15.7 | 1.6-150000.3.20.1 | [SUSE-SU-2026:2983-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-2983-1.md) | Jul 14, 2026 | | Linux | jq sles 16.0 | 1.7.1-160000.3.1 | [SUSE-SU-2026:22566-1](https://patchblox.com/security/data/fix/linux/suse-su-2026-22566-1.md) | Jul 7, 2026 | | Linux | jq-debuginfo Fedora 43 | 1.8.1-3.fc43 | [FEDORA-2026-4E57162966](https://patchblox.com/security/data/fix/linux/fedora-2026-4e57162966.md) | Apr 16, 2026 | | Linux | jq-debuginfo amzn 2023 | 1.8.1-59.amzn2023 | [ALAS2023-2026-1815](https://patchblox.com/security/data/fix/linux/alas2023-2026-1815.md) | Jun 8, 2026 | | Linux | jq-debugsource Fedora 43 | 1.8.1-3.fc43 | [FEDORA-2026-4E57162966](https://patchblox.com/security/data/fix/linux/fedora-2026-4e57162966.md) | Apr 16, 2026 | | Linux | jq-debugsource amzn 2023 | 1.8.1-59.amzn2023 | [ALAS2023-2026-1815](https://patchblox.com/security/data/fix/linux/alas2023-2026-1815.md) | Jun 8, 2026 | | Linux | jq-devel Fedora 43 | 1.8.1-3.fc43 | [FEDORA-2026-4E57162966](https://patchblox.com/security/data/fix/linux/fedora-2026-4e57162966.md) | Apr 16, 2026 | | Linux | jq-devel amzn 2023 | 1.8.1-59.amzn2023 | [ALAS2023-2026-1815](https://patchblox.com/security/data/fix/linux/alas2023-2026-1815.md) | Jun 8, 2026 | | Linux | libjq1 Ubuntu 18.04.6 LTS (bionic) | 1.5+dfsg-2ubuntu0.1~esm2 | [libjq1 1.5+dfsg-2ubuntu0.1~esm2](https://patchblox.com/security/data/fix/linux/ubuntu-bionic-libjq1-1.5-dfsg-2ubuntu0.1-esm2.md) | Apr 13, 2026 | | Linux | libjq1 Ubuntu 20.04 LTS (focal) | 1.6-1ubuntu0.20.04.1+esm2 | [libjq1 1.6-1ubuntu0.20.04.1+esm2](https://patchblox.com/security/data/fix/linux/ubuntu-focal-libjq1-1.6-1ubuntu0.20.04.1-esm2.md) | Apr 13, 2026 | | Linux | libjq1 Ubuntu 22.04.1 LTS (jammy) | 1.6-2.1ubuntu3.2 | [libjq1 1.6-2.1ubuntu3.2](https://patchblox.com/security/data/fix/linux/ubuntu-jammy-libjq1-1.6-2.1ubuntu3.2.md) | Apr 13, 2026 | | Linux | libjq1 Ubuntu 24.04.5 LTS (noble) | 1.7.1-3ubuntu0.24.04.2 | [libjq1 1.7.1-3ubuntu0.24.04.2](https://patchblox.com/security/data/fix/linux/ubuntu-noble-libjq1-1.7.1-3ubuntu0.24.04.2.md) | Apr 13, 2026 | | Linux | libjq1 Ubuntu 25.10 (questing) | 1.8.1-3ubuntu1.1 | [libjq1 1.8.1-3ubuntu1.1](https://patchblox.com/security/data/fix/linux/ubuntu-questing-libjq1-1.8.1-3ubuntu1.1.md) | Apr 13, 2026 | | Linux | libjq1 Ubuntu 26.04.1 LTS (resolute) | 1.8.1-4ubuntu2 | [libjq1 1.8.1-4ubuntu2](https://patchblox.com/security/data/fix/linux/ubuntu-resolute-libjq1-1.8.1-4ubuntu2.md) | Apr 13, 2026 | --- Data as of 2026-11-08T06:59:42Z UTC.
