Microsoft Copilot Personal Flaws Could Let One Click Exfiltrate Data From Connected Apps
Varonis Threat Labs disclosed CoSnitch (CVE-2026-24301, CVSS 8.8), a one-click vulnerability chain in Microsoft Copilot Personal that lets a specially crafted Copilot URL auto-execute attacker-supplied instructions on page load. The injected prompt can query connected services (Gmail, Drive, Calendar, OneDrive), encode results into an outbound URL exfiltrated through Copilot's legitimate URL-fetching, and persistently poison Copilot memory via hidden instructions in a webpage submitted for summarization. Microsoft deployed a service-side fix on August 18, 2026; enterprise Copilot was unaffected and no in-the-wild exploitation was observed. Details →First reported paloaltonetworks.com
A Vault with a Heap-View: The Uncomfortable Space Between AgentCore Harness and Identity
Palo Alto Networks' Unit 42 demonstrated that AWS AgentCore AI agents can be tricked via prompt injection into exfiltrating credentials in plaintext, despite the platform's encrypted secrets vault.

Two prompt injection paths into Rovo: one fixed (RovoBlast), one open.
Martin Runge's community write-up analyzes two prompt-injection techniques against Atlassian's Rovo AI assistant: RovoBlast (disclosed by Varonis Threat Labs at DEF CON 34), which abused a rovoChatPrompt URL parameter to inject instructions into an authenticated session and was fixed server-side by Atlassian on 8 July 2026; and an indirect prompt-injection method from PromptArmor that hides malicious instructions in content Rovo processes (Jira issues, Confluence, PDFs) and exfiltrates data via Markdown image and URL-retrieval requests. The second path is noted as still open, and disabling org-level web search does not stop it because the URL retrieval tool remains available. Details →First reported · updated · 6 reports nhimg.org
AI Agent Memory Poisoning: Persistent Agent Attacks
An explainer on agent memory poisoning argues that, unlike a one-shot prompt injection, a single malicious write to an agent's persistent memory is retrieved and executed across future sessions against users who never saw the attack. It synthesizes red-team research including AgentPoison (backdooring agent memory/RAG stores), MINJA (query-only memory injection), a systematic MPBench study, and MemGhost stealth email-based injection, then recommends architectural defenses: authorizing writes outside the model, provenance stamping, trust-weighted retrieval, and quarantining new writes.

Why do authorised AI agent tool calls still create exfiltration risk in practice?
An NHI Management Group FAQ explains why authorised AI agent tool calls still create data-exfiltration risk: systems typically validate the caller and function name but not the intent encoded in argument values, so a valid tool invocation (email, ticketing, database export, webhook) can carry a malicious or overly broad parameter that leaks sensitive data through normal workflows. It recommends parameter validation, output filtering, redaction before execution, scoped permissions, and destination/payload policy checks, referencing OWASP Agentic AI Top 10, NIST AI RMF, MITRE ATLAS, and CIS Controls.
