Mattermost versions 10.5.x <= 10.5.1, 9.11.x <= 9.11.9 fail to check if a file has been deleted when creating a bookmark which allows an attacker who knows the IDs of deleted files to obtain metadata of the files via bookmark creation.

### Summary gorilla/csrf is vulnerable to CSRF via form submission from origins that share a top level domain with the target origin. ### Details gorilla/csrf does not validate the Origin header against an allowlist. Its executes its validation of the Referer header for cross-origin requests only when it believes the request is being served over TLS. It determines this by inspecting the `r.URL.Scheme` value. However, this value is never populated for "server" requests [per the Go spec](https://pkg.go.dev/net/http#Request), and so this check does not run in practice. ``` // URL specifies either the URI being requested (for server // requests) or the URL to access (for client requests). // // For server requests, the URL is parsed from the URI // supplied on the Request-Line as stored in RequestURI. For // most requests, fields other than Path and RawQuery will be // empty. (See [RFC 7230, Section 5.3](https://rfc-editor.org/rfc/rfc7230.html#section-5.3)) // // For client r...

### Summary Access token from query string is not redacted and is potentially exposed in system logs which may be persisted. ### Details The access token in `req.query` is not redacted when the `LOG_STYLE` is set to `raw`. If these logs are not properly sanitized or protected, an attacker with access to it can potentially gain administrative control, leading to unauthorized data access and manipulation. ### PoC 1. Set `LOG_LEVEL="raw"` in the environment. 2. Send a request with the `access_token` in the query string. 3. Notice that the `access_token` in `req.query` is not redacted. ### Impact It impacts systems where the `LOG_STYLE` is set to `raw`. The `access_token` in the query could potentially be a long-lived static token. Users with impacted systems should rotate their static tokens if they were provided using query string.

Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to restrict certain operations on system admins to only other system admins, which allows delegated granular administration users with the "Edit Other Users" permission to perform unauthorized modifications to system administrators via improper permission validation.

A Path Traversal "Zip Slip" vulnerability has been identified in mholt/archiver in Go. This vulnerability allows using a crafted ZIP file containing path traversal symlinks to create or overwrite files with the user's privileges or application utilizing the library. When using the archiver.Unarchive functionality with ZIP files, like this: archiver.Unarchive(zipFile, outputDir),  A crafted ZIP file can be extracted in such a way that it writes files to the affected system with the same privileges as the application executing this vulnerable functionality. Consequently, sensitive files may be overwritten, potentially leading to privilege escalation, code execution, and other severe outcomes in some cases. It's worth noting that a similar vulnerability was found in TAR files (CVE-2024-0406). Although a fix was implemented, it hasn't been officially released, and the affected project has since been deprecated. The successor to mholt/archiver is a new project called mholt/archives, and i...

Incorrect handle provided in unspecified circumstances in Mojo in Google Chrome on Windows prior to 134.0.6998.177 allowed a remote attacker to perform a sandbox escape via a malicious file. (Chromium security severity: High) https://nvd.nist.gov/vuln/detail/CVE-2025-2783 https://chromereleases.googleblog.com/2025/03/stable-channel-update-for-desktop_25.html https://issues.chromium.org/issues/405143032

## Summary `jupyter-remote-desktop-proxy` was meant to rely on UNIX sockets readable only by the current user since version 3.0.0, but when used with TigerVNC, the VNC server started by `jupyter-remote-desktop-proxy` were still accessible via the network. This vulnerability does not affect users having TurboVNC as the `vncserver` executable. ## Credits This vulnerability was identified by Arne Gottwald at University of Göttingen and analyzed, reported, and reviewed by @frejanordsiek.

### Impact When using the ch-go library, under a specific condition when the query includes a large, uncompressed malicious external data, it is possible for an attacker in control of such data to smuggle another query packet into the connection stream. ### Patches If you are using ch-go library, we recommend you to update to at least version 0.65.0. ### Credit This issue was found by lixts and reported through our bugcrowd program.

SSH servers which implement file transfer protocols are vulnerable to a denial of service attack from clients which complete the key exchange slowly, or not at all, causing pending content to be read into memory, but never transmitted.

### Impact It is possible to inject malicious code into the HTML content of an email notification, which is then rendered on the preview. There is no issue when rendering the email via normal means (a delivered email). This would require access to the form's email notification settings. ### Patches This has been fixed in Formie 2.1.44. Users should ensure they are running at least this version.
