ISTA-DASLab/Qwen3.8-27B-GSQ-RCO-GGUF — new model trending #3 on Hugging Face

ISTA-DASLab releases GSQ-RCO non-uniform GGUF quantizations of Qwen3.8-27B down to 2.5 bpw, with task-lossless IQ3_S matching BF16 benchmark scores.

ISTA-DASLab released GGUF quantizations of Qwen3.8-27B produced with GSQ (Gumbel-Softmax Quantization) and RCO (Riemannian Constrained Optimization), non-uniform methods that allocate per-tensor precision via gradient-based search under a total size budget. Four checkpoints range from 2.50 bpw (8.4 GB) to 3.50 bpw (11.8 GB), plus a BF16 vision projector (mmproj) enabling multimodal use. The recommended IQ3_S build is task-lossless, matching the BF16 base exactly on AIME25 (100.00) and LiveCodeBench v6 (85.71) at roughly one fifth of the BF16 size. Optional -mtp variants add a Multi-Token Prediction head for speculative decoding in llama.cpp.

Stop playing with the CISO role. Fix cybersecurity leadership

Op-ed argues the CISO role is overloaded and advocates elevating a business-first Chief Security Officer above it.

The author contends that business-alignment failures in cybersecurity are structural rather than communication problems, with CISOs expected to act simultaneously as technologists, strategists, risk executives, and board advisers. The piece proposes a distinct Chief Security Officer role focused on enterprise protection, business continuity, and cross-functional decision authority, with the CISO retaining technical cybersecurity responsibility and potentially reporting to the CSO. It argues this model would give executive ownership of business protection while preserving technical depth.

Lovable CTO: The Future of SaaS Is Apps That Agents Can Use

Lovable pivots from app building to exposing app functions as agent-callable capabilities via hosted MCP servers, raising a $400M Series C at a $13.3B valuation.

Lovable CTO Fabian Hedin outlined a strategy of turning published applications into agent-accessible capabilities by exposing selected functions as tools through a hosted MCP server, usable from ChatGPT, Claude, and other MCP-compatible clients. The company reports surpassing a $500M annualized revenue run rate, more than 60 million projects created, over 900 million monthly visits to Lovable-built apps, and usage by employees at nearly two-thirds of the Fortune 500. Menlo Ventures led a $400M Series C this month alongside EQT's Scaleup Europe Fund, valuing the company at $13.3 billion. Lovable evolved from the open-source GPT Engineer tool, became a commercial product in November 2024, and now competes with platforms like Vercel in AI-generated software hosting.

U.S. CISA adds PaperCut NG/MF flaws to its Known Exploited Vulnerabilities catalog

CISA added two actively exploited PaperCut NG/MF pre-auth flaws to the KEV catalog; federal agencies must patch by September 14.

CISA added CVE-2026-81578 (CVSS 8.8, missing authentication for critical function) and CVE-2026-82078 (CVSS 9.4, unsafe reflection) in PaperCut NG/MF to its Known Exploited Vulnerabilities catalog. Huntress confirmed active pre-authentication RCE exploitation in two customer environments and reproduced the full chain against a clean PaperCut NG 25.0.11 server, chaining the auth bypass into unsafe Java class loading for SYSTEM-level execution. About 47% of roughly 2,500 tracked PaperCut installs still run version 23 or earlier with no patch available, and observed attacker activity was limited to system discovery commands.

Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Forescout used Anthropic's Claude to port a working pre-auth RCE exploit for CVE-2021-31886 between WAGO PLCs, executing ARM shellcode on live hardware.

Forescout Vedere Labs used Claude interactively to port an RCE exploit for CVE-2021-31886, a CVSS 9.8 stack buffer overflow in the Nucleus FTP server's USER command, from a WAGO 750-852 to a WAGO 750-831 PLC, running attacker-supplied ARM shellcode. The final RCE stage cost $535.74 in API usage over 8 hours 32 minutes, and a follow-up attempt to build a C2 implant permanently bricked the device. CERT@VDE lists many Nucleus V1-based WAGO models as vulnerable with no updates available; Siemens plans no Nucleus NET remediation. The work follows a joint NSA/CISA/FBI/DOE/EPA advisory warning of AI-generated exploitation scripts targeting internet-exposed Siemens S7 PLCs.

CISA Warns of N-able N-central RCE Vulnerability Exploited in the Wild

CISA added CVE-2026-86218, a CVSS 10.0 unauthenticated RCE in N-able N-central RMM, to its KEV catalog; on-premises admins must patch to 2026.3.1.14.

CISA added CVE-2026-86218, a CVSS 10.0 static code injection (CWE-96) enabling unauthenticated RCE in N-able N-central, to the Known Exploited Vulnerabilities catalog on September 8, 2026. The flaw affects all on-premises builds before 2026.3.1.14 across the 2025.4 through 2026.3 release lines; N-able shipped Hotfix 4 for 2026.3 on September 5-6, 2026. Huntress research indicates at least one customer's N-central instance was compromised on September 4, and federal civilian agencies must mitigate by September 11 under BOD 26-04. Hosted environments were patched server-side, but a compromised RMM server can serve as a single point of entry into entire MSP client bases.
