#14: Hidden in White

Top Story: Prompt Injection Goes Operational — For two years, prompt injection has mostly been a lab demo. ModelScope MS-Agent: a max-severity hole with no fix (CVE-2026-2256). — A command-injection flaw in Alibaba's widely used MS-Agent toolkit lets an attacker run arbitrary commands on the host running the agent (CVSS 9.8). LMDeploy: 13 hours from disclosure to exploitation (CVE-2026-33626). — Earlier this spring, a server-side request forgery flaw in the LMDeploy serving framework — think of it as tricking the server into making requests on the attacker's behalf — went from public advisory to active exploitation in roughly 13 hours, faster than any human patch cycle. CrewAI: four flaws in one agent framework. — The CrewAI orchestration framework picked up four separate vulnerabilities this spring (CVE-2026-2275, -2285, -2286, -2287), catalogued together by CERT/CC (VU#221883). Snowflake buys Natoma to govern what AI agents can touch. — Snowflake (NYSE: SNOW) signed a definitive agreement on May 27 to acquire Natoma, an enterprise platform that secures how AI agents connect to corporate systems through the Model Context Protocol (MCP) — the emerging standard for plugging agents into tools and data. CodeIntegrity raises $5M to put guardrails around agents at runtime. — The seed round (led by Syn Ventures, with Antler and Boost VC) backs a "deterministic control layer" for LLM agents — the idea that because agents behave unpredictably, you wrap them in enforceable, rule-based limits on what they're allowed to do in the moment. EU AI Act: deepfake-labeling rules approach their deadline. — The Act's Article 50 transparency obligations require that AI-generated and manipulated content be labeled or watermarked, with an enforcement window in August 2026. Pentagon formalizes its split with Anthropic. — After designating Anthropic a supply-chain risk in March, the Department of Defense moved in May to source frontier AI from other vendors. Anthropic's vulnerability-hunting AI is finding flaws faster than anyone can patch. — One month into Project Glasswing, Anthropic and roughly 50 partners say its restricted "Mythos" model has uncovered more than 10,000 high- or critical-severity vulnerabilities in the open-source software that underpins the internet — Cloudflare alone found 2,000 bugs, Mozilla fixed 271 in Firefox (about 10× its prior rate), and the UK's AI Security Institute called it the first model to clear both of its multi-step attack simulations end to end.

#13: The zero-day you can't patch

Top Story: The Week Trust Broke Twice — Two stories landed in the same 72 hours that belong in the same frame. NVIDIA NemoClaw sandbox bypass (CVE-2026-24222). — Lasso Security demonstrated that AI agents running inside NVIDIA's NemoClaw/OpenShell sandbox can exfiltrate sensitive data through tools the sandbox explicitly allows. vm2 sandbox escape wave: 13 CVEs, CVSS 9.0–10.0. — Between May 4 and May 7, researchers disclosed 13 sandbox escape vulnerabilities in vm2, the popular Node.js library used to isolate untrusted JavaScript. Cisco: "Reading Between the Pixels" (multimodal prompt injection). — Cisco's AI research team published Part 2 of their VLM safety research, demonstrating that small pixel-level perturbations (bounded at 12.5%) can bypass safety filters in vision-language models. UK ICO: AI security is now a GDPR Article 32 duty. — The Information Commissioner's Office published a five-step guide declaring that AI-powered attacks (prompt injection, AI-enhanced phishing, deepfake social engineering, automated vulnerability exploitation) must be treated as present-day threats under GDPR's "appropriate technical and organizational measures" requirement. Verizon DBIR 2026: vulnerability exploitation overtakes stolen credentials. — For the first time, vulnerability exploitation is the #1 initial breach vector at 31%, surpassing stolen credentials which fell to 13%.

#12: Agentic Speed — both sides of the race just went AI

Top Story: The Race at Agentic Speed — Two things happened in the same week that belong in the same sentence. TeamPCP releases Shai-Hulud source code, launches BreachForums "supply chain challenge." — The group posted the complete worm framework to GitHub (since removed, but forked) with detailed deployment instructions, and announced a contest on BreachForums offering $1,000 in Monero to anyone who uses it to compromise open-source packages. TanStack CI cache poisoned, hitting OpenAI and Mistral AI. — A pull request from a throwaway fork (attributed to TeamPCP's ongoing supply-chain campaign) triggered a workflow that wrote to the shared CI cache. node-ipc compromised via inactive maintainer account (690K weekly downloads). — Three malicious versions exfiltrate credentials and secrets via DNS TXT queries to a fake Azure-themed domain — same package that shipped protestware in 2022, different attacker, far more capable. Palo Alto Networks' first AI-driven "Patch Wednesday" produced 26 CVEs — versus their typical fewer than five. — As part of Project Glasswing and the Trusted Access for Cyber program, Palo Alto ran frontier models (Mythos, Claude Opus 4.7, GPT-5.5-Cyber) against their own 130+ products. XBOW independently benchmarks Anthropic's Mythos for offensive security. — Confirmed: Mythos is "a significant step up over all existing models" for finding vulnerability candidates from source code. Akamai acquires LayerX for $205M (all-cash). — AI and browser security platform providing shadow AI discovery, gen-AI data loss prevention, and protection for AI browsers and plugins. OpenAI in talks with EU regulators to provide access to a cyber-focused GPT-5.5 model — that can identify and exploit software vulnerabilities, after EU cybersecurity agencies were unable to gain access to Anthropic's Mythos.

#11: Look, an Instruction!

Top Story: The Prompt Was the Payload — Two Agent-Framework RCEs in Seven Days — Two independent disclosures landed inside seven days, and they collapse to the same sentence: a model read an instruction it shouldn't have trusted, and a tool downstream did exactly what the parsed text said. Cisco announces intent to acquire Astrix Security. — Cisco's May 4 blog post by SVP Peter Bailey says Astrix will fold into Cisco Identity Intelligence, Cisco Secure Access, Duo IAM, and Splunk. An X user drained ~$150,000 from a Grok-linked Bankr wallet via Morse-encoded prompt injection (May 4, 2026). — The mechanics, per Giskard's write-up: the attacker first sent a "Bankr Club Membership NFT" to Grok's auto-provisioned wallet, which granted the holder "Executive" permissions and bypassed standard transfer limits. HiddenLayer — "AI Threat Landscape Report 2026." — The headline figure surfaced via the report's coverage: roughly 1 in 8 reported AI breaches now involves agentic systems, alongside the recurring supply-chain-of-models statistic that 93% of orgs use public or open-weight model repositories and most don't scan inbound models consistently. The full PDF is gated; numbers are reported as cited unless you pull the original. Curator's Corner: "Look, an instruction!" That's the bug. Curated by Asaf Nakash. Voices by AI. Opinions by human.
