Binarly found six U-Boot flaws, including two that enable code execution during boot image verification, impacting 50+ releases. Binarly’s research team has found six vulnerabilities in U-Boot, the open-source bootloader that runs on home routers, smart cameras, server management controllers, and a large portion of the embedded hardware that powers the internet. All six are […]

Unauthenticated Flaw Allows Full Router, Network TakeoverA hidden backdoor, disclosed by CERT/CC and found in multiple firmware versions made by Chinese manufacturer Tenda, bypasses authentication and could grant attackers administrative access. Researchers are reporting exploitation and an Nmap script is making vulnerable devices easier to identify.

Attackers wasted little time targeting the latest memory disclosure flaw in Citrix's NetScaler products, after researchers published a proof-of-concept exploit (PoC).

Researchers found a shell injection flaw in 10 of 11 popular open-source AI agents, allowing attackers to bypass command filters. Adversa AI just published a survey, titled “GuardFall: a universal shell injection vulnerability in open-source AI agents,” of eleven open-source AI coding and computer-use agents, and the headline finding is uncomfortable: ten of them leave […]

DirtyClone: a Linux kernel privilege escalation that silently rewrites executables in memory, leaving no disk trace. Patch now. JFrog Security Research published a working exploit walkthrough on June 25 for CVE-2026-43503 (CVSS score of 8.8), a Linux kernel privilege escalation they call DirtyClone. It’s the fourth vulnerability in the DirtyFrag family, all sharing the same […]

Cybersecurity researchers have disclosed details of four vulnerabilities in Dify, an open-source agentic workflow platform with more than 146,000 GitHub stars, that could allow attackers to stealthily read artificial intelligence (AI) conversions from other customers' applications without requiring authentication

Cybersecurity researchers have disclosed details of three now-patched security flaws impacting LangGraph, including a critical vulnerability chain that could result in remote code execution

Claroty Warns of Downtime, 'Devastating' Impact of Vulnerabilities in OT SystemsVulnerabilities in backup power devices and heating and cooling control systems widely used in data centers could enable remote cyberattacks and result in costly downtime and "devastating" operational impact, according to new research from OT security firm Claroty.

Gamaredon exploits a WinRAR flaw to drop modular, nearly fileless malware on Ukrainian targets, hiding payloads in Windows streams and resolving C2s via Telegram. Sekoia’s Threat Detection & Research team dropped a YARA rule in late December 2025 to hunt for new initial access vectors, and by January 2026 it had already generated a dozen […]

Cybersecurity researchers have disclosed a security flaw in Gitea, an open-source, self-hosted platform for version control, that allows unauthenticated remote attackers to pull private container images from Gitea deployments without requiring an account, password, or other credentials

Cybersecurity researchers have disclosed details of a vulnerability in the Linux kernel that remained undetected for nine years

Cybersecurity researchers have disclosed a set of four security flaws in OpenClaw that could be chained to achieve data theft, privilege escalation, and persistence

Cybersecurity researchers have disclosed multiple security vulnerabilities impacting NGINX Plus and NGINX Open, including a critical flaw that remained undetected for 18 years

Cybersecurity researchers have disclosed a critical security vulnerability in Ollama that, if successfully exploited, could allow a remote, unauthenticated attacker to leak its entire process memory

No Patches Yet Available, After Third Party Published Vulnerability DetailsSecurity researchers have discovered a new, critical flaw in the Linux kernel that attackers can exploit to gain root access. No patches are yet available to fix "Dirty Frag," the second new local privilege escalation flaw to be found in two weeks, following the similar "Copy Fail" vulnerability.

CISA has warned that threat actors have started exploiting the "Copy Fail" Linux security vulnerability in the wild, one day after Theori researchers disclosed it and shared a proof-of-concept (PoC) exploit. [...]
