# Summary Affected versions of Better Auth allow an external request to configure `baseURL` when it isn’t defined through any other means. This can be abused to poison the router’s base path, causing all routes to return 404 for all users. This issue is only exploitable when `baseURL` is not explicitly configured (e.g., `BETTER_AUTH_URL` is missing) *and* the attacker is able to make the very first request to the server after startup. In properly configured environments or typical managed hosting platforms, this fallback behavior cannot be reached. # Details A combination of `X-Forwarded-Host` and `X-Forwarded-Proto` is implicitly trusted. This allows the first request to configure baseURL whenever it is not explicitly configured. Here's the code that reads the headers: <img width="631" height="219" alt="headers" src="https://github.com/user-attachments/assets/b3fb0078-a62f-4058-9d0b-4afbd30c4953" /> Here's the call to `getBaseURL()`, the result is assigned to `ctx.baseURL`. <i...

### Impact when using the extended query parser in express (`'query parser': 'extended'`), the `request.query` object inherits all object prototype properties, but these properties can be overwritten by query string parameter keys that match the property names > [!IMPORTANT] > the extended query parser is the default in express 4; this was changed in express 5 which by default uses the simple query parser ### Patches the issue has been patched to ensure `request.query` is a plain object so `request.query` no longer has object prototype properties. this brings the default behavior of extended query parsing in line with express's default simple query parser ### Workaround this only impacts users using extended query parsing (`'query parser': 'extended'`), which is the default in express 4, but not express 5. all users are encouraged to upgrade to the patched versions, but can otherwise work around this issue: #### provide `qs` directly and specify `plainObjects: true` ```js ap...

Hackers aren’t kicking down the door anymore. They just use the same tools we use every day — code packages, cloud accounts, email, chat, phones, and “trusted” partners — and turn them against us. One bad download can leak your keys. One weak vendor can expose many customers at once. One guest invite, one link on a phone, one bug in a common tool, and suddenly your mail, chats, repos, and

Practicing good “operations security” is essential to staying safe online. Here's a complete guide for teenagers (and anyone else) who wants to button up their digital lives.

Cybersecurity researchers have shed light on a cross-tenant blind spot that allows attackers to bypass Microsoft Defender for Office 365 protections via the guest access feature in Teams. "When users operate as guests in another tenant, their protections are determined entirely by that hosting environment, not by their home organization," Ontinue security researcher Rhys Downing said in a report

Mattermost versions 10.12.x <= 10.12.1, 10.11.x <= 10.11.4, 10.5.x <= 10.5.12, 11.0.x <= 11.0.3 fail to properly validate OAuth state tokens during OpenID Connect authentication which allows an authenticated attacker with team creation privileges to take over a user account via manipulation of authentication data during the OAuth completion flow. This requires email verification to be disabled (default: disabled), OAuth/OpenID Connect to be enabled, and the attacker to control two users in the SSO system with one of them never having logged into Mattermost.

Scattered LAPSUS$ Hunters admin "Rey," allegedly a 15-year-old named Saif Khader from Jordan, has been named in a report linking him to the group. He denies the claim.

Hackers have been busy again this week. From fake voice calls and AI-powered malware to huge money-laundering busts and new scams, there’s a lot happening in the cyber world. Criminals are getting creative — using smart tricks to steal data, sound real, and hide in plain sight. But they’re not the only ones moving fast. Governments and security teams are fighting back, shutting down fake

Myanmar’s military has been blowing up parts of the KK Park scam compound. Experts say the actions are likely for show.

Enterprises today are expected to have at least 6-8 detection tools, as detection is considered a standard investment and the first line of defense. Yet security leaders struggle to justify dedicating resources further down the alert lifecycle to their superiors. As a result, most organizations' security investments are asymmetrical, robust detection tools paired with an under-resourced SOC,
