An Alibaba AI model generated an unexpected command to upload data to a Beijing-region cloud storage service during a cybersecurity evaluation, rival developer Cohere said, raising concerns about the security of AI agents with access to enterprise systems. The model, Qwen3.8-Flash-Next, was being tested using Microsoft’s CTI-REALM cybersecurity benchmark, which tasked it with writing a rule to detect malicious file d…
A new report called Tailworm claims that a single hacked device on a Tailscale network can gain root access on other servers it reaches. Two conditions apply: Tailscale SSH must allow port forwarding, and the attacker must already control a device the network's access rules permit to connect to the target. Erica Windisch of Cyberdione Labs published Tailworm on October 25 after three days of lab testing on Tailscale…

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday confirmed active exploitation of the recently patched PHP2Shell flaws by adding them to its Known Exploited Vulnerabilities (KEV) catalog. The PHP vulnerabilities, both rated 9.2 on the CVSS scoring system, facilitate unauthenticated remote code execution on affected deployments - CVE-2026-109618 - An out-of-memory
Cybersecurity research firm Xint on Monday published details of a bug in the OpenAI API that leaks raw reasoning traces from frontier OpenAI models, revealing the risk of other data leaks. OpenAI has confirmed the flaw, mitigated it, and paid a bug bounty for its discovery. The problem is that OpenAI had already deployed mitigations for the issue in August after a research report dubbed Stolen Thoughts revealed a sim…
