### Summary A low-permission user can create new accounts through a direct API request instead of being restricted to the intended interface. ### PoC A low-permission user sends a crafted API request to the user-creation endpoint and the system creates the account successfully.  ### Impact This allows attackers to create unauthorized accounts.

The second wave of the Shai-Hulud supply chain attack has spilled over to the Maven ecosystem after compromising more than 830 packages in the npm registry. The Socket Research Team said it identified a Maven Central package named org.mvnpm:posthog-node:4.18.1 that embeds the same two components associated with Sha1-Hulud: the "setup_bun.js" loader and the main payload "bun_environment.js." "

This holiday season, as teams run lean and cyber threats rise, being open with what — and how — you share can protect both information and relationships.

If you're using community tools like Chocolatey or Winget to keep systems updated, you're not alone. These platforms are fast, flexible, and easy to work with—making them favorites for IT teams. But there’s a catch... The very tools that make your job easier might also be the reason your systems are at risk. These tools are run by the community. That means anyone can add or update packages. Some

# Summary Affected versions of the better-auth passkey plugin allow users with any valid session to delete arbitrary passkeys via their ID using `POST /passkey/delete-passkey`. # Details `ctx.body.id` is implicitly trusted and used in passkey deletion queries. better-auth applications configured with `useNumberId` may use auto incrementing IDs which makes it trivial to delete all passkeys via enumeration.

### Impact When a Node.js application using the Sentry SDK has `sendDefaultPii: true` it is possible to inadvertently send certain sensitive HTTP headers, including the `Cookie` header, to Sentry. Those headers would be stored within the Sentry organization as part of the associated trace. A person with access to the Sentry organization could then view and use these sensitive values to impersonate or escalate their privileges within a user's application. Users may be impacted if: 1. The Sentry SDK configuration has `sendDefaultPii` set to `true` 2. The application uses one of the Node.js Sentry SDKs with version from `10.11.0` to `10.26.0` inclusively: - @sentry/astro - @sentry/aws-serverless - @sentry/bun - @sentry/google-cloud-serverless - @sentry/nestjs - @sentry/nextjs - @sentry/node - @sentry/node-core - @sentry/nuxt - @sentry/remix - @sentry/solidstart - @sentry/sveltekit Users can check if their project was affected, by visiting Explore → Traces and searching for “http.requ...

The Shai Hulud worm's "Second Coming" has compromised over 26,000 public repositories. We detail the attacker's mistake, the target packages, and mandatory security tips.

Multiple security vendors are sounding the alarm about a second wave of attacks targeting the npm registry in a manner that's reminiscent of the Shai-Hulud attack. The new supply chain campaign, dubbed Sha1-Hulud, has compromised hundreds of npm packages, according to reports from Aikido, HelixGuard, Koi Security, Socket, Step Security, and Wiz. The trojanized npm packages were uploaded to

This week saw a lot of new cyber trouble. Hackers hit Fortinet and Chrome with new 0-day bugs. They also broke into supply chains and SaaS tools. Many hid inside trusted apps, browser alerts, and software updates. Big firms like Microsoft, Salesforce, and Google had to react fast — stopping DDoS attacks, blocking bad links, and fixing live flaws. Reports also showed how fast fake news, AI

Due to an error in sed command parsing, it was possible to bypass the Claude Code read-only validation and write to arbitrary files on the host system. 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.
