Oj - Use-After-Free in Oj::Doc Iterators via Reentrant Close

Summary Oj::Doc iterators eachvalue, eachchild, eachleaf are vulnerable to a heap use-after-free. When a Ruby block yielded during iteration calls doc.close or d.close, the document's heap memory is freed while the C iterator is still running. When control returns from the block, the iterator rea...

CVE-2026-48096

A flaw was found in OpenFGA, an authorization/permission engine. When iterator caching is enabled, distinct authorization check requests can generate identical cache keys. This can cause OpenFGA to reuse an outdated or incorrect cached result for subsequent requests. Such a flaw may lead to...

PyO3 has an Out-of-bounds Read in `nth` / `nth_back` for `PyList` and `PyTuple` iterators

PyO3 0.24.0 added optimized implementations of Iterator::nth and DoubleEndedIterator::nthback for the BoundListIterator and BoundTupleIterator types. These implementations computed the target index using unchecked usize addition index + n before bounds-checking against the sequence length, then...
