An anonymous researcher published a repository called "exploitarium" containing over 80 zero-day exploits and proof-of-concept code targeting various software vulnerabilities. The dump includes exploits for widely used enterprise and consumer applications, raising significant security concerns across the industry.

Bishop Fox researchers discovered an unauthenticated remote code execution chain in UniFi OS that allows attackers to gain root access on Ubiquiti Cloud Gateways and Dream Machines. The exploit leverages multiple vulnerabilities including insecure firmware encryption, a hidden API on a secondary port, and improper input validation. Ubiquiti has released patches following responsible disclosure.

A vulnerability in an IDE extension can be exploited for Remote Code Execution (RCE) by manipulating its communication protocol. The article demonstrates how an attacker can inject arbitrary commands, highlighting security risks in IDE plugins.

The article explains how a software supply chain attack exploited Visual Studio Code extensions to inject malicious code, turning the IDE into a Remote Code Execution (RCE) endpoint. It details the attack method, the risks of trusting third-party extensions, and recommends security measures like extension auditing and network restrictions.

A critical vulnerability (CVE-2025-27113) in FFmpeg, dubbed PixelSmash, allows attackers to weaponize media files by exploiting a flaw in the software's audio buffer handling, potentially enabling remote code execution. The flaw affects FFmpeg versions prior to 7.1.1 and poses risks to applications and services that process untrusted media.

An anonymous GitHub account named "exploitarium" is releasing multiple undisclosed zero-day exploits in bulk, raising concerns among cybersecurity communities about potential widespread impact.

The article details a sophisticated cyberattack likely linked to a nation-state, targeting the company via a complex exploit chain. The attack failed due to a minor implementation error in the exploit, allowing defenders to detect and block it before any damage occurred. The post provides a technical breakdown of the attack's stages, from initial compromise attempts to the eventual failure point.

The page describes CVE-2026-46331, a vulnerability involving packet_edit_meme, which enables page cache poisoning attacks.

Six critical vulnerabilities (CVSS 9.9) were discovered in Canonical's LXD container/hypervisor tool. The flaws could allow arbitrary code execution and privilege escalation. Patches have been released; users are urged to update immediately.

A security researcher discovered a critical vulnerability (CVE-2026-LGTM) in a widely used open-source library, allowing remote code execution. The issue was responsibly disclosed and patched within 24 hours. No active exploitation in the wild was reported before the fix was deployed.

A critical vulnerability in the BadBlocker ad-blocking app for Apple devices could have let attackers remotely execute code and take full control of devices via a single server request. The flaw affected up to 11 million users. The developer has since released a fix.

A critical vulnerability named PixelSmash has been discovered in FFmpeg, allowing attackers to weaponize media files by exploiting flaws in the software's processing of multimedia content. The flaw could potentially enable remote code execution when a malicious file is processed, posing significant security risks to users and systems relying on FFmpeg.

A UK student discovered that their school's network was left severely exposed, lacking basic security measures, allowing unauthorized access. The student demonstrated the vulnerability by accessing sensitive systems without credentials before reporting the issue.

Expat 2.8.2 has been released, addressing 13 vulnerabilities including high-severity issues like CVE-2025-27113 (heap use-after-free) and CVE-2025-27786 (infinite loop). The update patches flaws in XML processing functions such as XML_ParseBuffer, dtdCopy, and nextScaffoldPart, affecting both standalone and embedded library usage. Users are advised to upgrade to the latest version.

Security researchers at Aisle discovered six new CVEs in the curl and libcurl library, including the oldest reported issue in the project's history. The vulnerabilities range from a 2009 double-free bug to various crash-inducing flaws, all of which have been patched by the curl project.

Daniel Stenberg, creator of curl, describes a CVE dispute he initiated after a researcher filed a low-severity report that he argued was not a security vulnerability. He explains the process of formally disputing the CVE assignment through MITRE, which eventually resulted in the CVE being rejected. The post serves as a tutorial on how developers can challenge questionable CVE assignments.

Security researchers at Mythos uncovered a memory leak vulnerability nicknamed 'Squidbleed' in the Squid web proxy software, which had remained undetected since the Clinton administration. The flaw potentially exposes sensitive data and affects a widely used open-source proxy.
