Description

Ghidra versions through 12.1.4 contain a heap use-after-free vulnerability in the decompiler's Funcdata::opInsertAfter function caused by stale INDIRECT effect-op references. Attackers can craft a malicious binary with a specific x86-64 sequence that triggers the vulnerability during decompilation, causing the decompile helper process to crash and denying service to analysts and automated analysis pipelines.

CVE-2026-100604

ClawHub (openclaw/clawhub) contains an incorrect authorization vulnerability in the ClawHub application/backend: an organization-owned skill retains the ownerUserId of its original publisher, and transfer and lifecycle authorization checks trust that historical user before requiring current organization privileges. An authenticated user who originally published an organization skill can therefore transfer, delete, or restore that skill — taking control of its trusted name and history — even after their organization privileges have been revoked or downgraded. The issue was confirmed at revision cbfee7343ddc867316dd9b3de6fa8856730f9f41; the complete historical affected range was not established. It is fixed by PR #3680, included in revision 8c2de6c506bb4efabe3f0c2ffb8370b9e23d4650, which was deployed to clawhub.ai on 2026-09-11; self-hosted deployments should update to that revision or a later descendant. The npm CLI and OpenClaw runtime are separate products and are not affected.

CVE-2026-100505

Ghidra versions 11.2 through 12.1.4 contain a heap out-of-bounds read vulnerability in StringManager::getCodepoint when decoding multi-byte UTF-8, UTF-16, or UTF-32 characters without validating remaining buffer length. Attackers can craft malicious binaries with constant byte stores ending in multi-byte lead units to trigger out-of-bounds reads that crash the decompiler or leak adjacent heap memory into decompiled output.
