Traefik: Pre-authentication decision bypass due to forwarded alias spoofing

Summary There is a high severity authentication bypass vulnerability in Traefik's ForwardAuth and snippet-based authentication middleware. Traefik's forwarded-header sanitization logic targets only canonical header names e.g., X-Forwarded-Proto and does not strip or normalize alias variants that...

Insufficient Verification of Data Authenticity

Overview Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity in the ForwardAuth middleware when trustForwardHeader is set to false and the deployment is behind a trusted upstream proxy. An attacker can gain unauthorized access to protected backend...

CVE-2026-41342

OpenClaw before 2026.3.28 contains an authentication bypass vulnerability in the remote onboarding component that persists unauthenticated discovery endpoints without explicit trust confirmation. Attackers can spoof discovery endpoints to redirect onboarding toward malicious gateways and capture...

BIT-OAUTH2-PROXY-2026-40575 OAuth2 Proxy has an Authentication Bypass via X-Forwarded-Uri Header Spoofing

OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. Versions 7.5.0 through 7.15.1 may trust a client-supplied X-Forwarded-Uri header when --reverse-proxy is enabled and --skip-auth-regex or --skip-auth-route is configured. An attacker can spoof this header so OAut...

CVE-2026-40567 FreeScout has HTML Injection in Outgoing Emails via Unsanitized Customer Name in Signature Variables

FreeScout is a free self-hosted help desk and shared mailbox. Prior to version 1.8.213, an unauthenticated attacker can inject arbitrary HTML into outgoing emails generated by FreeScout by sending an email with a crafted From display name. The name is stored in the database without sanitization a...

CVE-2026-41299

OpenClaw before 2026.3.28 contains an authorization bypass vulnerability in the chat.send gateway method where ACP-only provenance fields are gated by self-declared client metadata from WebSocket handshake rather than verified authorization state. Authenticated operator clients can spoof ACP...

CVE-2026-41299 OpenClaw < 2026.3.28 - Client Identity Spoofing in chat.send Gateway Provenance Guard

OpenClaw before 2026.3.28 contains an authorization bypass vulnerability in the chat.send gateway method where ACP-only provenance fields are gated by self-declared client metadata from WebSocket handshake rather than verified authorization state. Authenticated operator clients can spoof ACP...

CVE-2026-40505

A flaw was found in MuPDF mutool. This vulnerability allows a local attacker to embed malicious ANSI escape sequences within a PDF's metadata. When a user views the PDF's information using the mutool info command, these unsanitized sequences are processed by the terminal. This can lead to the...

PT-2026-33222

Name of the Vulnerable Software and Affected Versions MuPDF mutool affected versions not specified Description MuPDF mutool fails to sanitize PDF metadata fields before writing them to terminal output. This allows the injection of arbitrary ANSI escape sequences—codes used to control terminal...

curl: lib/http2.c: SSL connections accept non-HTTP push schemes (incomplete fix for 2e8c922a)

Summary: settransferurl in lib/http2.c validates the :scheme pseudo-header of PUSHPROMISE frames only when !viasslconn — a guard added by commit 2e8c922a to block non-TLS connections from accepting TLS-scheme pushes. The symmetric case was not addressed: over TLS, viasslconn is TRUE, the guard at...

EUVD-2026-21456

OpenClaw before 2026.3.22 contains an identity spoofing vulnerability in ACP permission resolution that trusts conflicting tool identity hints from rawInput and metadata. Attackers can spoof tool identities through rawInput parameters to suppress dangerous-tool prompting and bypass security...

PT-2026-31962

OpenClaw versions 2026.2.13 through 2026.3.24 contain an ANSI escape sequence injection vulnerability in approval prompts that allows attackers to spoof terminal output. Untrusted tool metadata can carry ANSI control sequences into approval prompts and permission logs, enabling attackers to...

CVE-2026-39959 Tmds.DBus: malicious D-Bus peers can spoof signals, exhaust file descriptor resources, and cause denial of service

Tmds.DBus provides .NET libraries for working with D-Bus from .NET. Tmds.DBus and Tmds.DBus.Protocol are vulnerable to malicious D-Bus peers. A peer on the same bus can spoof signals by impersonating the owner of a well-known name, exhaust system resources or cause file descriptor spillover by...

ruby: use of predictable source port and transaction id in DNS requests done by resolv.rb module

resolv.rb in Ruby 1.8.5 and earlier, 1.8.6 before 1.8.6-p287, 1.8.7 before 1.8.7-p72, and 1.9 r18423 and earlier uses sequential transaction IDs and constant source ports for DNS requests, which makes it easier for remote attackers to spoof DNS responses, a different vulnerability than...
