Thread by Elvis Saravia (omarsar0) summarising an Anthropic-led paper on pretraining data poisoning of CLI agents. Poisoning 0.1% of pretraining data planted a remote code execution backdoor in Qwen3 models (0.6B, 1.7B, 4B) trained from scratch. It survived SFT, DPO and RL, and fired on about 92% of triggered prompts at 4B. At a 0.0005% poison rate (about 2,500 documents) it still fired on 1.4% of prompts.

The uploader demonstrates a remote code execution exploit chain against Muse, an assistant system that uses the pdfdetach utility to parse PDF attachments. The exploit leverages a path traversal vulnerability during file extraction to drop a malicious shared library and an LD_PRELOAD configuration file.

Unit 42 threat brief on PHP2Shell, two PHP remote code execution flaws, CVE-2026-109618 and CVE-2026-109619 (CVSS 4.0 9.2), both caused by longjmp() error handling that leaves memory uninitialized or freed. Cortex Xpanse counted over 22.6 million exposed instances. The 29 October 2026 update says attackers chained PHP2Shell with a Linux kernel privilege escalation against internet-exposed PAN-OS management interfaces. An earlier 23 October claim of post-compromise activity was retracted on 25 October.

Trail of Bits post says it achieved remote code execution through a Brotli decoder bug in Linux lab setups: Node.js 24.22.0 with Express 5.3.0 via the standard JSON parser (x86-64 and ARM64), and Electron 41.10.7 (x86-64) with a custom decoding service. Exploitation needs a carefully matched setup and repeated attempts. A scanner by ToBScottA finds hidden copies of the decoder, including in stripped binaries.

Four vulnerabilities in EPICS Base 7.0.10 and earlier, the control-system toolkit used at ITER and the Advanced Photon Source, were disclosed by CISA. CVE-2026-114595 (CVSS 9.8) is an integer overflow that could allow remote code execution, though only an out-of-bounds heap write and crash were demonstrated. All flaws sit in Channel Access and pvAccess handling (TCP 5064 and 5075), need no authentication, and are fixed in 7.0.11.

Interconnects podcast with Nathan Lambert and Florian Brand on Kimi K3.1 Pro and the AI cyber landscape. Kimi says it down-weighted cyber data in mid-training so its open weights do not extend offensive capability. They discuss the PHP2Shell remote code execution bug, the repeat LiteLLM compromise from an API key left in GitHub for five months, abliterated model APIs, and trusted-access programs from OpenAI and Anthropic. The transcript was truncated at the very end.

Galaxy Research's weekly brief includes a section on PHP2Shell, two decade-old PHP remote code execution bugs affecting versions back to 5.4, patched in an emergency release. It reports an Amazon honeypot exploit attempt four days before disclosure, thousands of attempts in the 10 hours before the patch per Cloudflare's Matthew Prince, and NSA and FBI offline advice. The author argues the bugs were found with GPT-5.6 Sol and that defence must become agentic. It also lists the week's other incidents, including a CVSS 10.0 GitLab bug and eMudhra's guessable private keys.

Post summarising Pillar Security's finding of a remote code execution flaw in OpenCode, the open-source AI coding agent. Versions 1.0.137 through 1.18.32 could run code from a remote MCP server during OAuth sign-in on Windows and WSL, with no prompt injection needed. The fix is in 1.18.33 (released 28 September). No advisory or CVE was issued, so scanners will not flag old installs. Interim advice is to remove unvetted remote MCP servers.
