FalconFlank Turns an EDR Feature Into a Privilege Question
A newly released proof-of-concept spotlights how an endpoint security remediation path can become sensitive when a privileged product touches untrusted files.
When a Repo Becomes a Trap: GitSpawn and the New Trust Problem in AI Coding Agents
A newly disclosed vulnerability class shows how coding assistants that run Git in the background can cross from reading a project to executing attacker-influenced behavior.
Public Avast PoC Raises a Familiar Nightmare: Local Code to SYSTEM
A proof-of-concept named PrettyPrague puts a spotlight on a hard truth in endpoint security: when a trusted protection product has a privilege bug, the jump from user to SYSTEM can become the real prize.
When an AI Model Learns to Move an Exploit, OT Defenders Should Pay Attention
A lab demonstration shows how a known PLC flaw can be adapted across related embedded systems, turning shared middleware into the real attack surface.
When a Print Server Becomes an Entry Point
A new Metasploit module around PaperCut NG/MF shows how a browser-facing admin plane can turn into a path from authentication bypass to server-side code execution.
When a Robot’s Bluetooth Door Becomes the Control Room
A disclosure around the Unitree G1 shows how a nearby BLE flaw can turn from convenience feature to a motion-safety problem if trust boundaries are too loose.
Routers That Arrive Preloaded: Why Hidden Access Paths Cut Deeper Than a Firmware Bug
A case involving white-label networking gear shows how undocumented access paths can turn ordinary infrastructure into a standing trust risk.
PostgreSQL PoC Alert Turns a Routine Database Notice Into a Security Sprint
A high-severity PostgreSQL flaw with an available Proof of Concept is the kind of signal defenders cannot afford to ignore, even before the full technical path is publicly nailed down.
Trusted VPN Software, Untrusted Privilege Boundaries
Five disclosed flaws in GlobalProtect show how a local foothold can turn a corporate endpoint into a higher-value target.
Windows Pipes, Hidden Trust: The Small Interface That Can Become a Big Problem
Named pipes are built for speed inside Windows, but weak access controls can let an ordinary process reach a service that was meant to stay privileged.
When the Prompt Is Hidden, the Guardrails Go Blind
Researchers describe a cryptographic trick that keeps malicious instructions unreadable until a trusted runtime decrypts them, creating a new challenge for AI safety controls.
When Reverse-Engineering Tools Start Thinking, Deception Becomes a Defense
Quarkslab argues that anti-reversing code may be more useful if it returns plausible wrong answers instead of crashing, because automated analysts can treat crashes as useful signals.
Inside the Signed Driver That Can Turn Defender’s Trust Against Itself
A Microsoft Defender boot-time removal driver has drawn attention for a simple reason: in kernel mode, a trusted component can become a control surface if its file and registry actions are reachable by an attacker.
Expired at the Counter: The Research Demo That Turned a Visa Contactless Card Back on
Researchers at the University of Massachusetts Amherst demonstrated a contactless payment flaw in which an expired Visa card could appear valid to a point-of-sale terminal without any break in the card’s cryptography.
One Newline, Two Parsers, and a Quiet Path to Cookie Theft
CRLF injection only looks small until a proxy, CDN, and backend disagree on where an HTTP message begins and ends.
A Tiny CRLF Slip Can Split the HTTP Brain and Put Sessions at Risk
New desync research shows how a stray newline in an HTTP header can turn into request smuggling, with possible paths to HttpOnly cookie abuse and account takeover.
Elastic Doors That Stay Open: RAVEN Shows Why Password Rotations Can Fail
A controlled offensive demonstration around Elasticsearch shows how API keys, snapshots, and scheduled jobs can keep access alive even after defenders change passwords.
AI-Driven Review Finds a Dangerous Weak Spot in SAML Trust Checks
A research pipeline built around Claude Code surfaced authentication bypass and signature-validation flaws in multiple open-source SAML implementations, putting federation logic back under the microscope.
The SAML Trapdoor: How AI Helped Expose Fragile Login Trust
An AI-assisted investigation into open-source SAML libraries has put a familiar weak spot back in the spotlight: when XML signature checks and trust decisions drift apart, single sign-on can fail in dangerous ways.
When Stolen Code Meets Agentic AI, Vulnerability Hunting Stops Being Human-Speed
A reported two-day burst of AI-assisted discovery in a stolen repository shows how source-code theft can turn into a rapid validation problem, not just a data-loss event.
