🚨 Critical Okta Access Gateway flaw allows administrators to execute system commands; CVE-2026-115547
The vulnerability affects the Okta Access Gateway Admin Console and carries a CVSS score of 9.1.
⠀
An authenticated administrator can submit specially formatted configuration values to execute commands within the context of the OAG service account.
Key details:
• Network exploitable
• Low attack complexity
• Administrative access required
• No user interaction required
• Affects OAG versions before 2026.10.2
⠀
Okta has resolved the vulnerability in Access Gateway 2026.10.2. Administrators should manually upgrade affected appliances.

For the next few days or weeks, anyone now has a root CA thanks to eMudhra. Time to have some fun with MiTMing unwilling devices!
Clean indirect syscalls on Windows x64. It single-steps a hooked ntdll stub with the CPU trap flag to learn the live System Service Number and the syscall opcode, then jumps to that opcode with different arguments and a spoofed return address. The public proof of concept injects a calc.exe launcher into Notepad.

CVE-2026-23866: Finding a Whatsapp NDay
core-jmp.org/2026/10/cve-202…
CVE-2026-23866 described incomplete validation of WhatsApp AI-rich Instagram Reel messages that could make another device fetch an arbitrary URL. numb3rs used only the public NVD text, grepped an iOS 25.9.72 IPA for AiRich, and proved a 1-click UIApplication.openURL path. The CVE’s automatic media sink was not reproduced; a 10 October edit points at LaTeX unifiedData image URLs.

STM32F401 Xbox One controller from “we have SWD” to a live CoreSight instruction trace. ETM and TPIU are programmed from OpenOCD, SWO is captured on PB3 with a hobbyist logic analyzer, and Ghidra explains why the first decode dies: the PLL moves the baud rate, then firmware steals the pin for I2C2.

One go. One core, spin in the slot handler until zero. Windows times the command, not the slot: splitting 450 ms across that read is still one late completion. If slots chain, the hook runs again and adds time. Test got 450 ms back. Drop is one command held past the OS timer.
JTAG found the handler. Patch is a SMART 0xBE RAM write into loaded overlay 0x11. It lives until power-off. Fragile part is the host: ~450 ms on one core, once per slot of 40. Windows drops the disk on timeout. First sample 0 ms (cache). Xbox never saw it: stock lit the ring.
Cisco published CVE-2026-76504, a critical authentication bypass in Catalyst SD-WAN Manager. Landon Rice at VulnCheck showed that a single percent-encoded POST to /%6a_security_check plus a reserved Viptela username mints an admin JSESSIONID, because getRequestURI() does not decode while WildFly does. About 1,500 vManage consoles were internet-exposed; the bug was exploited as a zero-day.

Reverse Engineering a Ledger Nano X Hardware Implant
core-jmp.org/2026/10/reverse…
Reverse-engineered a real Ledger Nano X hardware implant for HARDWEAR.IO 2026 in Santa Clara. The add-on board does not break the Secure Element: it watches the OLED SPI bus, template-matches BIP-39 glyphs, stores the recovery seed at flash 0x7000, and sends it out over a Luat Air700E LTE modem with a Vodafone NL data eSIM. This article walks the 78-slide talk in source order and adds kitchen-table and operator notes.

Simon Koeck's Google DevSite write-up: a pre-auth Flask session cookie on developers.google.com carried a pickled OAuth flow whose client_secret was also the Flask SECRET_KEY. Forging the cookie reached pickle.loads. Unauthenticated RCE, proved with time.sleep, paid $90,000, fixed 7 Oct 2026.

A leftover interpret: helper then sent named local files to a chat with no confirmation. One click, three tdata files, account takeover. Fixed in 7.2.9.

AnyPwn is a pre-approval remote code execution bug in AnyDesk Linux 8.0.2. The session protocol's mode-5 handler trusts a remote payload length, adds a 16-byte object header with 32-bit arithmetic, wraps to a tiny allocation, and copies attacker bytes using the original huge logical length. The public PoC talks TLS to TCP/7070 and runs an arbitrary command; the same parser is reachable over AnyDesk relays. Fixed in 8.0.3. This is not CVE-2025-27918.
