Model Context Protocol turned every developer’s laptop into a tool-calling agent host. The trust model that came with it is closer to npm circa 2016 than to anything a serious authorizing official would sign.
Trellix has confirmed unauthorized access to part of its source code repository. The disclosure is thin on detail and heavy on implications for every shop running Trellix EDR or XDR.
Theori’s Copy Fail flaw turns a nine-year-old in-place optimization in the kernel’s AEAD socket layer into a deterministic 4-byte page-cache write. No race, no offset hunting, no per-distro tuning. A 732-byte Python script edits a setuid binary’s cached pages and hands you root on Ubuntu, RHEL, SUSE, and Amazon Linux without modification.
Indirect prompt injection has graduated from a research curiosity to a routine cause of agent compromise. Here is what defenders are actually shipping in 2026, and where the control gaps still are.
Agentic AI breaks the assumptions baked into service accounts and long-lived API keys. Here is what an honest non-human identity model looks like when an LLM is the principal making the call.
Prompt injection isn’t a content-filtering problem. It’s a control-flow problem, and 2026’s serious agent deployments are starting to treat it that way.
A remote, unauthenticated heap use-after-free in OpenWidget 3.0.0–3.2.1 hands attackers code execution against ~14,200 internet-exposed instances. Here is the triage order defenders should be working through right now.
CNSA 2.0 deadlines are no longer abstract. Here is what crypto inventory, hybrid deployment, and agility actually look like when an assessor walks the floor in 2026.
Wiz Research disclosed a command injection in GitHub’s internal git pipeline that let any authenticated user reach RCE with a single git push. The root cause is the same one that has burned multi-service architectures for thirty years: trust boundaries that don’t actually exist.
A practitioner’s view of the realistic container escape surface in multi-tenant Kubernetes — kernel boundaries, runtime gaps, and the controls that actually move the needle.
