A threat actor posted about the zero-day exploit on the same day that Fortinet published a warning about known vulnerabilities under active exploitation.

Mattermost versions 10.5.x <= 10.5.1, 10.4.x <= 10.4.3, 9.11.x <= 9.11.9 fail to invalidate the cache when a user account is converted to a bot which allows an attacker to login to the bot exactly one time via normal credentials.

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...

A newly created inetpub folder turns out to be part of a Microsoft update against a vulnerability tracked as CVE-2025-21204

AI is changing cybersecurity faster than many defenders realize. Attackers are already using AI to automate reconnaissance, generate sophisticated phishing lures, and exploit vulnerabilities before security teams can react. Meanwhile, defenders are overwhelmed by massive amounts of data and alerts, struggling to process information quickly enough to identify real threats. AI offers a way to

Hackers exploit Fortinet flaws to plant stealth backdoors on FortiGate devices, maintaining access even after patches. Update to…

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.
