Atlas browser CSRF flaw lets attackers poison ChatGPT memory

⚠️ Researchers at LayerX disclosed a vulnerability in ChatGPT Atlas that can let attackers inject hidden instructions into a user's memory via a CSRF vector, contaminating stored context and persisting across sessions and devices. The exploit works by tricking an authenticated user to visit a malicious page which issues a CSRF request to silently write memory entries that later influence assistant responses. Detection requires behavioral hunting—correlating browser logs, exported chats and timestamped memory changes—since there are no file-based indicators. Administrators are advised to limit Atlas in enterprise pilots, export and review chat histories, and treat affected accounts as compromised until memory is cleared and credentials rotated.

Atlas Browser Flaw Lets Attackers Poison ChatGPT Memory

⚠️ Researchers at LayerX Security disclosed a vulnerability in OpenAI’s Atlas browser that allows attackers to inject hidden instructions into a user’s ChatGPT memory via a CSRF-style flow. An attacker lures a logged-in user to a malicious page, leverages existing authentication, and taints the account-level memory so subsequent prompts can trigger malicious behavior. LayerX reported the issue to OpenAI and advised enterprises to restrict Atlas use and monitor AI-driven anomalies. Detection relies on behavioral indicators rather than traditional malware artifacts.

ChatGPT Atlas 'Tainted Memories' CSRF Risk Exposes Accounts

⚠️ Researchers disclosed a CSRF-based vulnerability in ChatGPT Atlas that can inject malicious instructions into the assistant's persistent memory, potentially enabling arbitrary code execution, account takeover, or malware deployment. LayerX warns that corrupted memories persist across devices and sessions until manually deleted and that Atlas' anti-phishing defenses lag mainstream browsers. The flaw converts a convenience feature into a persistent attack vector that can be invoked during normal prompts.

Rockwell Automation 1783-NATR: Critical Remote Flaws

⚠️ Rockwell Automation's 1783-NATR network adapter contains multiple high-severity vulnerabilities, including missing authentication for critical functions, stored XSS, and CSRF. CISA assigns CVSS v4 9.9 for the most severe issue and warns these flaws can be exploited remotely with low complexity to cause denial-of-service, data modification, or credential compromise. Rockwell Automation recommends upgrading to 1.007 or later; CISA advises minimizing network exposure and isolating control networks.

ASP.NET Core Kestrel Flaw Earns 9.9 Severity Score Now

⚠️Microsoft patched a critical ASP.NET Core vulnerability in the built‑in Kestrel web server and assigned it a CVSS score of 9.9, the highest rating the vendor has ever issued. Tracked as CVE-2025-55315, the flaw enables authenticated attackers to use HTTP request smuggling to bypass security checks and could allow actions such as logging in as another user, bypassing CSRF protections, or performing injection attacks. Microsoft advises updating affected runtimes or rebuilding and redeploying self‑contained apps, while noting that reverse proxies or gateways may already mitigate exposure.

Understanding Cookie Types and How to Protect Them

🔒 This article explains how web cookies work, their classifications, and why session IDs are particularly valuable to attackers. It outlines common attack methods — including session sniffing over HTTP, cross‑site scripting (XSS), cross‑site request forgery (CSRF), and predictable session IDs — and describes specialized tracking like supercookies and evercookies. Practical advice for users and developers covers HTTPS, browser updates, cookie management, two‑factor authentication, cautious use of public Wi‑Fi, and preferring essential cookies only.
