Origin Validation Error vulnerability in livebook-dev livebook allows untrusted notebook output JavaScript to trigger session-wide keyboard shortcuts, including forced evaluation of all cells and runtime restart. Livebook's JS-view feature renders notebook-defined JavaScript inside a sandboxed, cross-origin iframe specifically because that JavaScript is untrusted. The trusted iframe shell in iframe/priv/static/iframe/v5.html forwards every keydown event fired in its own window to the parent page without consulting Event.isTrusted, so an event synthesized by the untrusted script through window.dispatchEvent is forwarded exactly as a genuine keystroke would be. The parent-side relay in assets/js/hooks/js_view.js reconstructs and re-dispatches it on the live page with no further validation, and because assets/js/hooks/session.js registers the global shortcut handler on the document in the capture phase, that handler acts on the replicated event regardless of how it was produced. Sandboxed output JavaScript can therefore drive Livebook's session-wide keyboard shortcuts. Two of them reach LivebookWeb.SessionLive and execute immediately with no confirmation: the shortcut for queueing full evaluation runs every cell in the notebook, and the shortcut for reconnecting the runtime disconnects and reconnects it, discarding in-memory state. A third shortcut deletes the focused cell behind a confirmation dialog that the user can permanently dismiss, after which it too executes silently. Forced full evaluation is the significant consequence, because it causes the notebook's own Elixir code to run without the user choosing to evaluate anything. A user who merely opens a notebook obtained from a third party, or reached from published documentation, can have its code executed on their runtime. Livebook also mirrors cell outputs to every connected client, so a malicious output triggers in a collaborator's browser as soon as it renders. This issue affects livebook: from 0.5.0 before 0.18.7 and from 0.19.0 before 0.19.9.

A flaw was found in the SAML broker component of Keycloak, which is used to manage identity federation and user authentication. The issue occurs because the IdP-initiated Single Sign-On endpoint fails to check if a provider is restricted to account linking only. This allows an attacker with control over a linked upstream identity to bypass login restrictions and gain full access to a local user account.

Improper Privilege Management in Google SecOps (Chronicle SOAR) versions prior to 6.3.85 on Google Cloud Platform allows an authenticated attacker to escalate privileges to system-level administrative access using a crafted internal authentication header. This vulnerability was patched with version 6.3.85, and no customer action is needed.

Baileys is a cocket-based TS/JavaScript API for WhatsApp Web. In versions prior to both 6.7.22 and 7.0.0-rc12, any Baileys session can be sent a malicious payload via the placeholderResendMessage and trigger a fake messages.upsert event with a fake message key and payload. This allows anyone to spoof messages. The same exploit also allows an attacker to corrupt the app state sync system by sending fake key shares, and also allows for history sync spoofing which also serves the same problem, injecting fake previous context or "on-demand" sync. This issue has been fixed in versions 6.7.22 and 7.0.0-rc12.

Inappropriate implementation in Media in Google Chrome on Windows prior to 151.0.7922.72 allowed a remote attacker who had compromised the renderer process to bypass same origin policy via a crafted HTML page. (Chromium security severity: Medium)
