Nintendo Switch Vulnerability Allows Attackers to Run Unauthorized Code on Your Console

Nintendo patched CVE-2026-82079, a CVSS 7.0 stack buffer overflow in original Switch local wireless allowing nearby code execution via QR-code workflows.

Nintendo patched CVE-2026-82079 (CVSS 4.0 base score 7.0, High), a stack-based buffer overflow in the original Switch's local wireless networking affecting firmware earlier than 23.0.0. An adjacent attacker must scan a QR code displayed by the console, via the Album "Send to Smartphone" feature or Mario Kart Live: Home Circuit, before crafted packets can corrupt memory and enable return-oriented programming for arbitrary code execution. EPSS is approximately 0.16%, Switch 2 is not affected, and Nintendo's advisory was published September 10, 2026.

GitHub Pays $100,000 Bounty for Critical RCE Flaw in Git Push Pipeline

GitHub paid Saif Ghani $100,000 for CVE-2026-3854, a critical unauthenticated RCE in its Git push pipeline allowing command execution on backend infrastructure.

GitHub awarded researcher Saif Ghani $100,000, its largest publicly disclosed bug bounty, for CVE-2026-3854, a critical unauthenticated remote code execution flaw in its Git push processing pipeline. A crafted repository URL could trigger arbitrary command execution on backend infrastructure, threatening source code integrity, repository secrets, and software supply chains. GitHub deployed mitigations and completed a patch rollout through coordinated disclosure before technical details became public.

Parallels Desktop Flaw Lets Unprivileged Mac Users Gain Root Access

JFrog's 'ParaShells' research details CVE-2026-90894, a Parallels Desktop local privilege escalation letting unprivileged macOS users gain root via tar argument injection.

JFrog researcher Yuval Moravchick disclosed CVE-2026-90894 ('ParaShells'), a critical local privilege escalation flaw demonstrated against Parallels Desktop 26.4.0 build 57513 on Apple silicon. The world-writable /var/run/prl_disp_service.socket accepts connections from unsigned clients, and argument injection into a tar extraction command via the --use-compress-program option executes attacker-controlled code with root privileges. The attack needs no administrator permissions, running VM, or Parallels-signed client, and a one-line PoC yielded a root shell. Risk is highest on developer workstations, shared training systems, and enterprise Macs.

VU#212479: Sentry Seer vulnerability allows attacker-controlled input to be executed in a privileged environment

CERT/CC details CVE-2026-90999: attacker-controlled Sentry telemetry can steer the Seer coding agent into executing attacker code with repository access.

CERT/CC published VU#212479 for CVE-2026-90999 in Sentry Seer: attacker-submitted events through public DSN endpoints flow into Seer's root-cause analysis, which is embedded directly into the coding agent's initial prompt. In the documented chain, the privileged coding agent downloads and executes an attacker-controlled package before any human review, yielding arbitrary code execution with access to connected source repositories. No vendor patch is available yet; mitigations include disabling automated remediation, restricting coding-agent package installation, and filtering telemetry before Seer analysis.

Microsoft Releases Emergency Windows 11 Update Following Patch Tuesday Bugs

Microsoft issued emergency Windows 11 update KB5129195 to fix Patch Tuesday regressions and fully close the CVE-2026-62721 privilege escalation flaw.

Microsoft shipped out-of-band cumulative update KB5129195 for Windows 11 24H2 and 25H2 (builds 26100.9457 and 26200.9457) after the September 8 Patch Tuesday rollup, which addressed over 960 CVEs including two actively exploited flaws, broke Remote Desktop Services, Hyper-V Plan9 folder sharing, and USB audio. The emergency release also strengthens the incomplete fix for CVE-2026-62721, an elevation-of-privilege flaw in the Windows User-Mode Power Service that could let a local attacker gain SYSTEM privileges. Companion patches cover Windows 11 26H1, Windows 10, and Windows Server. Some USB Audio Class 1.0 and AMD Radeon graphics issues remain unresolved.

WordPress Events Calendar Vulnerabilities Let Hackers Take Over 600,000 Websites

Two unauthenticated RCE flaws (CVSS 9.8) in The Events Calendar WordPress plugin threaten 600,000 sites; patched in 6.17.4.1.

Wordfence Argus disclosed two critical unauthenticated vulnerability chains in The Events Calendar WordPress plugin, tracked as CVE-2026-78006 and CVE-2026-78159, both scoring 9.8 CVSS. CVE-2026-78006 enables PHP object injection leading to RCE via a Lazy_Post_Collection gadget chain, while CVE-2026-78159 abuses Element_Classes::parse_array() to invoke wp_update_user() and reset the admin password. Exploitation works by injecting wp:legacy-widget Gutenberg markup through comments, using WordPress's moderation-preview hash to trigger the block before approval. StellarWP patched both flaws in version 6.17.4.1 after Wordfence's August 2026 disclosure.

Telegram Desktop Flaw Lets Attackers Steal Chat Messages Through Poisoned HTML Exports

Telegram Desktop XSS in bot inline keyboard buttons let attackers steal chat content from exported HTML archives; patched in 7.0.1.

ExPatch researchers Denis and Aleksander Rostilov found a stored cross-site scripting flaw in Telegram Desktop's HTML export feature, present since version 4.15.1 (March 2024). JavaScript hidden in bot inline keyboard button text executes when a user opens an exported chat HTML file with JavaScript enabled, exposing messages, metadata, and enabling DOM manipulation such as fake verification screens. Fixes shipped in Desktop Beta 6.9.4 (July 3, 2026) and Stable 7.0.1 (July 14, 2026), but previously exported HTML files remain unsafe.
