CVE-2026-44777: CWE-674: Uncontrolled Recursion in jqlang jq
CVE-2026-44777 is a medium severity vulnerability in the jq command-line JSON processor (version 1.8.2rc1 and earlier). The issue involves uncontrolled recursion in the ordinary module loader when two valid modules include each other, causing recursion without cycle detection. This can lead to potential denial of service or resource exhaustion. No official patch or remediation guidance is currently available from the vendor. Users should monitor vendor advisories for updates and avoid using mutually recursive modules until a fix is provided.
AI Analysis
Technical Summary
jq versions 1.8.2rc1 and earlier contain a vulnerability (CWE-674) where the ordinary module loader performs recursion without detecting cycles if two valid modules include each other. This uncontrolled recursion can cause the program to consume excessive resources or crash. The vulnerability has a CVSS 4.0 base score of 5.4, indicating medium severity. No patch or official remediation level has been published yet, and no known exploits are reported in the wild.
Potential Impact
The vulnerability can cause jq to enter uncontrolled recursion, potentially leading to denial of service through resource exhaustion or application crash when processing JSON modules that include each other cyclically. There is no indication of privilege escalation or data confidentiality impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid using jq modules that include each other cyclically to prevent triggering uncontrolled recursion.
