Allocation of Resources Without Limits or Throttling

Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the lack of enforced limits in the parser when processing JSON input. An attacker can cause excessive CPU and memory consumption by submitting very large or deeply nested JSON...

Linux Distros Unpatched Vulnerability : CVE-2026-54897

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. Prior to 3.17.2, Oj::Doc iterators eachvalue, eachchild, eachleaf were vulnerab...

CVE-2026-54902

Oj Optimized JSON is a JSON parser and Object marshaller packaged as a Ruby gem. Prior to version 3.17.2, is vulnerable to Use-After-Free when in SAJ mode. The Oj::Parser does not protect cached object keys ≥ 35 bytes from garbage collection, and a Ruby callback that triggers GC inside hashend ca...
