The third vulnerability, CVE -2026-44791 (GHSA-wrwr-h859-xh2r), is particularly alarming because it represents a patch bypass. It circumvents the previously issued fix for GHSA-hqr4-h3xv-9m3r in the XML node, reintroducing prototype pollution through a different code path. When chained with additional nodes, this too can escalate to RCE on the host.
