CVE-2026-54897: CWE-416: Use After Free in ohler55 ojCVE-2026-54897 0 Oj (Optimized JSON) is a Ruby gem for JSON parsing and object marshalling. Versions prior to 3.17.2 have a heap use-after-free vulnerability in Oj::Doc iterators (each_value, each_child, each_leaf). This occurs when a Ruby block yields during iteration and calls doc.close or d.close, freeing the document's heap memory while the C iterator is still active. The iterator then accesses freed memory, causing a use-after-free condition. This vulnerability has been fixed in version 3.17.2.
