Generative AI is making it even easier for attackers to exploit old and often forgotten network equipment. Replacing it takes investment, but Cisco is making the case that it’s worth it.

Improper access control in GitHub Copilot and Visual Studio Code allows an authorized attacker to bypass a security feature over a network.

Threat actors with ties to Iran engaged in cyber warfare as part of efforts to facilitate and enhance physical, real-world attacks, a trend that Amazon has called cyber-enabled kinetic targeting. The development is a sign that the lines between state-sponsored cyber attacks and kinetic warfare are increasingly blurring, necessitating the need for a new category of warfare, the tech giant's

Threat actors are leveraging bogus installers masquerading as popular software to trick users into installing malware as part of a global malvertising campaign dubbed TamperedChef. The end goal of the attacks is to establish persistence and deliver JavaScript malware that facilitates remote access and control, per a new report from Acronis Threat Research Unit (TRU). The campaign, per the

Red Hat Lightspeed (formerly Red Hat Insights) has long helped operations teams detect risks, open tickets, and share findings with the right tools, connecting proactive intelligence to everyday workflows.Much has changed, not only in Red Hat Lightspeed itself, but also in how organizations are using it. Across industries, teams have built custom dashboards, reporting portals, and IT service management (ITSM) integrations powered by the Red Hat Lightspeed API. Others have connected Red Hat Lightspeed data into continuous integration and delivery (CI/CD) pipelines, monitoring environments, and

In this episode of Uncanny Valley, we discuss our scoop about how the Department of Homeland Security illegally collected Chicago residents’ data for months, as well as the news of the week.

When running on a machine with Yarn 3.0 or above, Claude Code could have been tricked to execute code contained in a project via yarn plugins before the user accepted the startup trust dialog. Exploiting this would have required a user to start Claude Code in an untrusted directory and to be using Yarn 3.0 or above. Users on standard Claude Code auto-update will have received this fix automatically. Users performing manual updates are advised to update to the latest version. Thank you to Benjamin Faller, Redguard AG and Michael Hess for reporting this issue!

### Summary The esm.sh CDN service contains a Template Literal Injection vulnerability (CWE-94) in its CSS-to-JavaScript module conversion feature. When a CSS file is requested with the `?module` query parameter, esm.sh converts it to a JavaScript module by embedding the CSS content directly into a template literal without proper sanitization. An attacker can inject malicious JavaScript code using `${...}` expressions within CSS files, which will execute when the module is imported by victim applications. This enables Cross-Site Scripting (XSS) in browsers and Remote Code Execution (RCE) in Electron applications. **Root Cause:** The CSS module conversion logic (`router.go:1112-1119`) performs incomplete sanitization - it only checks for backticks (\`) but fails to escape template literal expressions (`${...}`), allowing arbitrary JavaScript execution when the CSS content is inserted into a template literal string. ### Details **File:** `server/router.go` **Lines:** 1112-1119 ...

### Summary The esm.sh CDN service is vulnerable to a Path Traversal (CWE-22) vulnerability during NPM package tarball extraction. An attacker can craft a malicious NPM package containing specially crafted file paths (e.g., `package/../../tmp/evil.js`). When esm.sh downloads and extracts this package, files may be written to arbitrary locations on the server, escaping the intended extraction directory. Uploading files containing `../` in the path is not allowed on official registries (npm, GitHub), but the `X-Npmrc` header allows specifying any arbitrary registry. By setting the registry to an attacker-controlled server via the `X-Npmrc` header, this vulnerability can be triggered. ### Details **file:** `server/npmrc.go` **line:** 552-567 ```go func extractPackageTarball(installDir string, pkgName string, tarball io.Reader) (err error) { pkgDir := path.Join(installDir, "node_modules", pkgName) tr := tar.NewReader(unziped) for { h, err := tr.Next...

## Summary When using Astro's Cloudflare adapter (@astrojs/cloudflare) with `output: 'server'`, the image optimization endpoint (`/_image`) contains a critical vulnerability in the `isRemoteAllowed()` function that unconditionally allows `data:` protocol URLs. This enables Cross-Site Scripting (XSS) attacks through malicious SVG payloads, bypassing domain restrictions and Content Security Policy protections. ## Details On-demand rendered sites built with Astro include an `/_image` endpoint for image optimization. While this endpoint is designed to restrict processing to local images and authorized remote domains (configured via `image.domains` or `image.remotePatterns`), a critical vulnerability exists in the underlying validation logic. The `isRemoteAllowed()` function in [packages/internal-helpers/src/remote.ts](https://github.com/withastro/astro/blob/b8ca69b97149becefaf89bf21853de9c905cdbb7/packages/internal-helpers/src/remote.ts) (lines 128-131) unconditionally allows ALL `data...
