Mattermost versions 10.11.x <= 10.11.1, 10.10.x <= 10.10.2, 10.5.x <= 10.5.10 fail to verify a user has permission to join a Mattermost team using the original invite token which allows any attacked to join any team on a Mattermost server regardless of restrictions via manipulating the OAuth state.

Mattermost versions 10.5.x <= 10.5.10, 10.11.x <= 10.11.2 fail to properly validate guest user permissions when adding channel members which allows guest users to add any team members to their private channels via the `/api/v4/channels/{channel_id}/members` endpoint

The online world is changing fast. Every week, new scams, hacks, and tricks show how easy it’s become to turn everyday technology into a weapon. Tools made to help us work, connect, and stay safe are now being used to steal, spy, and deceive. Hackers don’t always break systems anymore — they use them. They hide inside trusted apps, copy real websites, and trick people into giving up control

### Impact This vulnerability only affects users of the AWS attestor. Users of the AWS attestor could have unknowingly received a forged identity document. While this may seem unlikely, AWS recently issued a security bulletin about IMDS (Instance Metadata Service) impersonation.[^1] There are multiple locations where the verification of the identity document will mistakenly report a successful verification. - If a signature is not present or is empty https://github.com/in-toto/go-witness/blob/0c8bb30c143951d88b1d4b32f260c5f67d30137b/attestation/aws-iid/aws-iid.go#L161-L163 - If the RSA verification of the document fails for any reason https://github.com/in-toto/go-witness/blob/0c8bb30c143951d88b1d4b32f260c5f67d30137b/attestation/aws-iid/aws-iid.go#L192-L196 ### Workarounds The contents of the AWS attestation contain the identity document, signature, and public key that was used to verify the document. These attestations and their could be identity documents could be manually verif...

### Summary An SMTP Command Injection (CRLF Injection) vulnerability in Netty's SMTP codec allows a remote attacker who can control SMTP command parameters (e.g., an email recipient) to forge arbitrary emails from the trusted server. This bypasses standard email authentication and can be used to impersonate executives and forge high-stakes corporate communications. ### Details The root cause is the lack of input validation for Carriage Return (\r) and Line Feed (\n) characters in user-supplied parameters. The vulnerable code is in io.netty.handler.codec.smtp.DefaultSmtpRequest, where parameters are directly concatenated into the SMTP command string. For example, when SmtpRequests.rcpt(recipient) is called, a malicious recipient string containing CRLF sequences can inject a new, separate SMTP command. Because the injected commands are sent from the server's trusted IP, any resulting emails will likely pass SPF and DKIM checks, making them appear legitimate to the victim's email clien...

New research has uncovered that publishers of over 100 Visual Studio Code (VS Code) extensions leaked access tokens that could be exploited by bad actors to update the extensions, posing a critical software supply chain risk. "A leaked VSCode Marketplace or Open VSX PAT [personal access token] allows an attacker to directly distribute a malicious extension update across the entire install base,"
