Claude Code preview flaw exposed developer secrets

πŸ›‘οΈ Noma Security found a vulnerability in Anthropic’s Claude Code Desktop that let malicious JavaScript in HTML files execute via the app’s preview pane, potentially exposing local files and credentials. Files under 256KB were safely loaded with strict CSPs, but larger files were written to disk and rendered as file://, bypassing protections and allowing filesystem access. Anthropic collaborated on fixes and is preparing advisories and a CVE.

Docker fixes critical Docker Hub token transfer flaw

πŸ”’ Docker patched a critical Docker Hub flaw (CVE-2026-105445) that allowed personal access tokens (PATs) to be transferred when converting a personal account into an organization, potentially letting one user act as another in the registry. The bug, open from August 26, 2024, until the fix on September 30, 2026, was found by researchers Peter Molnar and Krisztian Hozak and named GhostPat. Docker says it found no evidence of exploitation and has reviewed conversions, deactivated affected tokens, and now requires consent and notification for ownership changes.

Apple to Tighten macOS Full Disk Access Controls

πŸ”’ Apple is moving to strengthen controls around the macOS Full Disk Access (FDA) setting after concerns that AI agents and some apps may misuse it to access sensitive data. The company said FDA can expose files, mail, messages, browsing history and backups, and plans updates to require explicit user actions before granting such deep access. The change appears prompted by incidents involving agentic tools like Meta's Muse and proof-of-concept exploits that demonstrated token theft and broader privilege amplification risks. Apple did not announce a rollout date but emphasized clearer user consent and heightened safeguards.

Windows KB5124010 causes crashes in AC-3 apps

🎧 Microsoft confirmed that the September 2026 preview update KB5124010 can cause some games and applications using AC-3 (Dolby Digital) audio decoding to crash or close unexpectedly. The update is optional unless devices run Windows 11 24H2 with automatic preview updates enabled. Microsoft noted many modern apps are unaffected because they use alternative decoding, and said it is investigating the issue and will provide further updates when available.

Microsoft to enforce CSP for Entra ID sign-ins

πŸ”’ Microsoft will begin enforcing stricter Content Security Policy (CSP) protections for Entra ID sign-ins starting mid-October 2026, allowing only scripts from trusted Microsoft CDN domains. The rollout will complete by late October 2026 and aims to block external script injection and cross-site scripting risks during browser-based authentication. Enterprise customers are urged to remove or test browser extensions and code-injection tools to avoid sign-in disruptions. MSAL and API-based flows are not affected because CSP applies only to browser-based sign-ins.

Understanding the Risks of Vibe‑Coded Mobile Apps

πŸ”’ Vibe coding lets developers generate apps quickly using AI, but this speed can introduce security and privacy oversights. Common issues include hardcoded secrets, missing input validation, weak encryption, and public-by-default settings that expose user data. Users should vet apps by checking the developer's reputation, permissions requested, privacy policy, security model, and any AI access. If an app is breached, change passwords, enable MFA, revoke connected permissions, and consider uninstalling or factory-resetting compromised devices.

Fixing Flock: Controls Needed as Misuse Patterns Emerge

πŸ” Flock Safety's networked license-plate readers and cameras can aid serious investigations but also log vast sensitive location data searchable across agencies. The company faces documented misuse and must move quickly to embed effective controls like short retention defaults, case-bound access, multifactor authentication and anomaly detection. Graduated retention, verified case tokens, tighter sharing defaults and independent audit are recommended to balance public safety and privacy.

September 2026 Windows update disrupts Always On VPN

πŸ”’ Microsoft warned administrators that the September 2026 Windows 11 security updates can cause Always On VPN connections to stall or repeatedly fail. The issue appears when profiles use automatic protocol selection between IKEv2 and SSTP, leaving connections stuck in a "Connecting" state or returning "The specified port is already in use." A temporary mitigation is to set the VPN profile to use either SSTP-only or IKEv2-only while Microsoft develops a permanent fix.
