CVE-2026-44777: CWE-674: Uncontrolled Recursion in jqlang jq
CVE-2026-44777 is a medium severity vulnerability in jq, a command-line JSON processor. Versions 1. 8. 2rc1 and earlier have an uncontrolled recursion issue in the ordinary module loader, which occurs when two valid modules include each other without cycle detection. This can lead to excessive recursion during module loading.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-44777 affects jq versions up to 1.8.2rc1. The ordinary module loader in jq recursively loads modules but lacks cycle detection, causing uncontrolled recursion if two modules include each other. This behavior can result in resource exhaustion or denial of service conditions. The CVSS 4.0 base score is 5.4, indicating medium severity, with an attack vector limited to local access and requiring user interaction.
Potential Impact
The uncontrolled recursion can cause jq to consume excessive resources, potentially leading to denial of service or application instability. There is no indication of remote exploitation or privilege escalation. The attack requires local access and user interaction, limiting the scope of impact.
Mitigation Recommendations
No official patch or remediation is currently available for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is released, avoid loading modules that may include each other recursively. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
