Summary
TinaCMS: Cross-origin postMessage handlers and rich-text URL-sanitization bypass enable stored XSS and session takeover
Details

TinaCMS registers window message listeners — the useTina overlay handler, the OAuth authentication popup handler, and the admin↔preview iframe GraphQL reducer — that act on event.data without verifying event.origin or event.source, and post messages using non-specific target origins. A page the victim visits (or a window in an opener/iframe relationship with a Tina admin) can forge messages to drive the editor, inject preview content, or observe/forge the OAuth popup channel to take over an authenticated editing session.

Fixed in #7056 by allow-listing trusted origins and verifying event.source (isFromAdmin, isFromTrustedPreviewOrigin), and by posting only to explicit target origins (never "*").

Note: the rich-text URL-sanitization issue previously bundled here has been split into its own advisory (GHSA-2vcc-5v34-9jc8) so each vulnerability can receive a distinct CVE.

GHSA-G88P-PPWJ-3QFF

Vulnerability from github – Published: 2025-09-24 18:30 – Updated: 2025-09-24 18:30
VLAI
Details

A vulnerability in the IPv6 Router Advertisement (RA) packet processing of Cisco Access Point Software could allow an unauthenticated, adjacent attacker to modify the IPv6 gateway on an affected device.

This vulnerability is due to a logic error in the processing of IPv6 RA packets that are received from wireless clients. An attacker could exploit this vulnerability by associating to a wireless network and sending a series of crafted IPv6 RA packets. A successful exploit could allow the attacker to temporarily change the IPv6 gateway of an affected device. This could also lead to intermittent packet loss for any wireless clients that are associated with the affected device.

GHSA-G8FC-VRCG-8VJG

Vulnerability from github – Published: 2024-04-15 18:13 – Updated: 2024-06-04 19:35
VLAI
Summary
Constallation has pods exposed to peers in VPC
Details

Impact

Cilium allows outside actors (world entity) to directly access pods with their internal pod IP, even if they are not exposed explicitly (e.g. via LoadBalancer). A pod that does not authenticate clients and that does not exclude world traffic via network policy may leak sensitive data to an attacker inside the cloud VPC.

Patches

The issue has been patched in v2.16.3.

Workarounds

This network policy excludes all world traffic. It mitigates the problem, but will also block all desired external traffic. If vulnerable pods are known, a policy can be crafted to only firewall those instead (see also https://docs.cilium.io/en/stable/security/policy/language/#access-to-from-outside-cluster).

Vulnerability from github – Published: 2023-10-04 21:30 – Updated: 2024-04-04 08:18
VLAI
Details

TouchLink packets processed after timeout or out of range due to Operation on a Resource after Expiration and Missing Release of Resource after Effective Lifetime may allow a device to be added outside of valid TouchLink range or pairing duration

This issue affects Ember ZNet 7.1.x from 7.1.3 through 7.1.5; 7.2.x from 7.2.0 through 7.2.3; Version 7.3 and later are unaffected

Mitigation
Architecture and Design
  • Use a mechanism that can validate the identity of the source, such as a certificate, and validate the integrity of data to ensure that it cannot be modified in transit using an Adversary-in-the-Middle (AITM) attack.
  • When designing functionality of actions in the URL scheme, consider whether the action should be accessible to all mobile applications, or if an allowlist of applications to interface with is appropriate.
CAPEC-500: WebView Injection

An adversary, through a previously installed malicious application, injects code into the context of a web page displayed by a WebView component. Through the injected code, an adversary is able to manipulate the DOM tree and cookies of the page, expose sensitive information, and can launch attacks against the web application from within the web page.

CAPEC-594: Traffic Injection

An adversary injects traffic into the target's network connection. The adversary is therefore able to degrade or disrupt the connection, and potentially modify the content. This is not a flooding attack, as the adversary is not focusing on exhausting resources. Instead, the adversary is crafting a specific input to affect the system in a particular way.

CAPEC-595: Connection Reset

In this attack pattern, an adversary injects a connection reset packet to one or both ends of a target's connection. The attacker is therefore able to have the target and/or the destination server sever the connection without having to directly filter the traffic between them.

CAPEC-596: TCP RST Injection

An adversary injects one or more TCP RST packets to a target after the target has made a HTTP GET request. The goal of this attack is to have the target and/or destination web server terminate the TCP connection.
