Presented here is a curated selection of noteworthy open-source cybersecurity solutions that have drawn recognition for their ability to enhance security postures across diverse settings. SkillSpector: NVIDIA’s open-source security scanner for AI agent skills SkillSpector is an open-source scanner from NVIDIA that reads an agent skill and tells you whether to install it. Point it at a directory, a

A selection of new open-source cybersecurity tools has been highlighted for their potential to improve security across various environments. These tools include solutions for AI agent security, software supply chain integrity, and automated penetration testing.
NVIDIA has released SkillSpector, an open-source security scanner designed to evaluate AI agent skills. Users can point SkillSpector at a directory, a zip file, a single SKILL.md file, or a Git URL. The tool then provides a list of findings, a risk score, and recommendations regarding the skill's safety for installation.
Another tool, Future AGI, offers an open-source platform for managing self-improving AI agents. Licensed under Apache 2.0, this self-hostable platform supports tracing, evaluating, simulating, and guardrailing Large Language Model (LLM) agents. Upon its initial boot, a self-hosted instance of Future AGI registers with the main Future AGI service, transmitting an instance ID, a version string, a deployment type, and the email addresses and domains of active administrative users.
For software supply chain security, Chainloop functions as an open-source evidence store and policy engine. This tool operates as a command-line interface within various CI/CD pipelines, including GitHub Actions, GitLab, Jenkins, or Dagger. It collects build artifacts, uploads them to content-addressable storage, and then references each artifact in a signed in-toto attestation. The in-toto specification is used to record the execution steps of a build process, enabling subsequent verification.
PentestGPT is an open-source agentic framework for automated penetration testing. This tool directs a large language model at a target system. In its default mode, it progresses through reconnaissance, exploitation, and walkthrough stages, with each stage informing the next. When switched to "pentest mode," the stages become asset discovery, vulnerability identification, and report generation, operating without human intervention.
Finally, Hazmat provides open-source containment for AI agents. This tool runs AI coding agents within a separate account on the user's machine. It supports various existing harnesses, such as Claude Code, Codex, OpenCode, and Cursor Agent, as well as custom scripts.
A weakness has been identified in Tenda CP3 27.5.57.101. This issue affects some unknown processing of the file Net/NetCheckPing.cpp. This manipulation of the argument interface_name/host causes os command injection. The attack can be initiated remotely.
A security flaw has been discovered in Tenda CP3 27.5.57.101. This vulnerability affects the function SystemAsh of the file Apis/system.c of the component Kylin. The manipulation of the argument AlarmVoiceURL results in os command injection. It is possible to launch the attack remotely.

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an advisory published on September 5. Sansec, which discovered the flaw and named it StyleSmuggler, said attacks started on September 4. "Sansec is publishing early
In BPF instructions that load/store a value from/to a scratch memory register the register index is an unsigned 32-bit integer and must not exceed 15, but libpcap BPF interpreter does not validate the value. In particular uncommon use cases a crafted filter program can cause the interpreter to try reading and writing the OS process memory in the 16GiB starting at the current stack frame on 64-bit architectures and in the entire address space on 32-bit architectures.

Attackers are exploiting two new PaperCut flaws to steal credentials and gain privileged access in education-sector attacks across the U.S. and Europe. Attackers are exploiting two recelty disclosed PaperCut flaws, CVE-2026-81578 and CVE-2026-82078, in attacks targeting schools and other education organizations in the U.S. and Europe, as reported by TheHackerNews. Arctic Wolf researchers observed

JetBrains is urging Cadence users to revoke and rotate all credentials following a security incident last month in which unidentified threat actors exploited a recently disclosed critical vulnerability in TeamCity to breach its own environment. "Cadence users should immediately revoke or rotate all credentials and secrets that may have been used to run their Cadence executions," JetBrains said.
