CVE-2026-46348 Mastodon: SSRF Bypass via IPv6 Unspecified Address (::)

Mastodon is a free, open-source social network server based on ActivityPub. Prior to 4.5.10, 4.4.17, and 4.3.23, the list of disallowed IP address ranges was lacking an IP address range that can be used to reach local IP addresses. An attacker can use an IP address in the affected range to make...

CVE-2026-46348

CVE-2026-46348 affects Mastodon servers prior to 4.5.10, 4.4.17, and 4.3.23. The issue stems from the disallowed IP range list lacking an IPv6 unspecified address (::), allowing an attacker to induce HTTP requests to loopback interfaces and potentially access private resources and services. Impac...

PT-2026-52114

Name of the Vulnerable Software and Affected Versions Appsmith versions prior to 2.1 Description An authenticated user can craft outbound requests that reach loopback-bound services inside the container. This occurs because the outbound HTTP host filter applied by WebClientUtils used by the REST...

Astra Linux – Vulnerability found in Linux 6.12, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: rxrpc: DATA/RESPONSE packets are also unshared when paged fragments are present. The DATA-packet handler in rxrpcinputcallevent and the RESPONSE handler in rxrpcverifyresponse copy the skb into a linear sequence before calling...

EUVD-2026-38115

Capgo before 12.128.2 contains a server-side request forgery vulnerability in webhook URL validation that allows loopback and internal addresses. Organization admins can configure webhooks pointing to localhost or 127.0.0.1, and when triggered, the backend performs outbound requests to these...

CVE-2026-56227

Capgo before 12.128.2 is affected by a server-side request forgery (SSRF) in webhook URL validation. The flaw permits configuring webhooks to loopback or internal addresses (e.g., localhost/127.0.0.1). When triggered, the backend makes outbound requests to those addresses, and error responses are...

CVE-2026-56227 Capgo - Server-Side Request Forgery via Webhook URL Validation

Capgo before 12.128.2 contains a server-side request forgery vulnerability in webhook URL validation that allows loopback and internal addresses. Organization admins can configure webhooks pointing to localhost or 127.0.0.1, and when triggered, the backend performs outbound requests to these...

Missing Authentication For Critical Function

github.com/tilt-dev/tilt is vulnerable to Missing Authentication for Critical Function. The vulnerability is due to the Tilt HUD HTTP server registering handlers without authentication middleware when bound to a non-loopback address, which allows an unauthenticated attacker to trigger...

GHSA-R46F-3RPW-HXRV Hugo: security.http.urls deny rules bypassed by alternate IPv4 encodings (SSRF)

Impact The default security.http.urls policy denies requests to loopback, internal, and cloud-metadata IPv4 literals e.g. http://127.0.0.1/, http://169.254.169.254/. The deny rule only matched dotted-decimal notation, so alternate IPv4 encodings of the same addresses — integer, hex, or octal, whi...

kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop

A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture aloop driver. This Use-After-Free UAF vulnerability occurs when loopbackcheckformat stops the capture side during a format change, while a concurrent close operation detaches or frees the runtime. An attacker could...

Tilt: Missing authentication on the network-exposed Tilt HUD server

Summary The Tilt HUD HTTP server exposes state-changing and sensitive-read endpoints with no authentication. When the HUD is bound to a non-loopback address, a network attacker can trigger the developer's pre-defined Tiltfile resources, tamper with Tiltfile arguments, read full engine state...

Missing Authentication for Critical Function

Overview Affected versions of this package are vulnerable to Missing Authentication for Critical Function via the HUD server when it is bound to a non-loopback address. An attacker can execute arbitrary developer-defined resources, modify arguments, and access sensitive engine state by making...

Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the WebsocketToken handler and the WebSocket upgrader process. An attacker can access sensitive session state and resource information by obtaining a CSRF token from an unauthenticated...

Tilt: Cross-site WebSocket hijacking of the Tilt HUD stream

Summary The Tilt HUD WebSocket /ws/view is gated by a CSRF token, but the token is served by an unauthenticated endpoint and the upgrader accepts any client that omits an Origin header. When the HUD is network-exposed, an attacker can open the HUD stream and read the developer's session state...

Tilt: Unauthenticated pprof debug endpoints on the Tilt HUD server

Summary The Tilt HUD server mounts Go's net/http/pprof handlers under /debug with no access control. When the HUD is network-exposed, an attacker can read process memory — including session and apiserver tokens — and hold the process under profiling. Details A blank import of net/http/pprof...

Information Exposure

Overview Affected versions of this package are vulnerable to Information Exposure via the pprof debug endpoints mounted under /debug without access control. An attacker can extract sensitive process memory, including session and apiserver tokens, and degrade server performance by holding the...
