When accepting a malicious intent from other installed apps, Firefox for Android accepted manifests from arbitrary file paths and allowed declaring webapp manifests for other origins. This could be used to gain fullscreen access for UI spoofing and could also lead to cross-origin attacks on targeted websites. Note: This issue is a different issue from CVE-2020-26954 and only affected Firefox for Android. Other operating systems are unaffected. This vulnerability affects Firefox < 86.

When following a link that opened an intent://-schemed URL, causing a custom tab to be opened, Firefox for Android could be tricked into displaying the incorrect URI. <br> *Note: This issue only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.7.

Cross-origin iframes that contained a login form could have been recognized by the login autofill service, and populated. This could have been used in clickjacking attacks, as well as be read across partitions in dynamic first party isolation. This vulnerability affects Firefox < 83.

It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.

The file-download implementation in Mozilla Firefox before 27.0 and SeaMonkey before 2.24 does not properly restrict the timing of button selections, which allows remote attackers to conduct clickjacking attacks, and trigger unintended launching of a downloaded file, via a crafted web site.

Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.

The exception page for the HTTPS-Only feature, displayed when a website is opened via HTTP, lacked an anti-clickjacking delay, potentially allowing an attacker to trick a user into granting an exception and loading a webpage over HTTP. This vulnerability was fixed in Firefox 140 and Thunderbird 140.

Data was not properly sanitized when decoding a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash. This vulnerability affects Firefox < 124.

This issue is fixed in tvOS 16.2, macOS Ventura 13.1, iOS 15.7.2 and iPadOS 15.7.2, iOS 16.2 and iPadOS 16.2, watchOS 9.2. Visiting a website that frames malicious content may lead to UI spoofing.

A CWE-1021: Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause the user to be tricked into performing unintended actions when external address frames are not properly restricted. Affected Products: NetBotz 4 - 355/450/455/550/570 (V4.7.0 and prior)

The commit 3730880 (April 2023) and v.0.9-beta1 of gugoan Economizzer is vulnerable to Clickjacking. Clickjacking, also known as a "UI redress attack", is when an attacker uses multiple transparent or opaque layers to trick a user into clicking on a button or link on another page when they were intending to click on the top-level page. Thus, the attacker is "hijacking" clicks meant for their page and routing them to another page, most likely owned by another application, domain, or both.

A CWE-1021: Improper Restriction of Rendered UI Layers or Frames vulnerability exists that could cause an adversary to trick the interface user/admin into interacting with the application in an unintended way when the product does not implement restrictions on the ability to render within frames on external addresses. Affected Products: Conext™ ComBox (All Versions)

The X-Frame-Options header in Rockwell Automation MicroLogix 1100/1400 Versions 21.007 and prior is not configured in the HTTP response, which could allow clickjacking attacks.

Improper restriction of rendered UI layers or frames issue exists in Wi-Fi AP UNIT 'AC-WPS-11ac series'. If a user views and clicks on the content on the malicious page while logged in, unintended operations may be performed.

Multiple vulnerabilities in the web interface of Cisco Webex Meetings could allow a remote attacker to conduct a cross-site scripting (XSS) attack or a frame hijacking attack against a user of the web interface.

An unauthenticated remote attacker can deceive users into performing unintended actions due to improper restriction of rendered UI layers or frames. 

your_spotify is an open source, self hosted Spotify tracking dashboard. YourSpotify version < 1.9.0 does not prevent other pages from displaying it in an iframe and is thus vulnerable to clickjacking. Clickjacking can be used to trick an existing user of YourSpotify to trigger actions, such as allowing signup of other users or deleting the current user account. Clickjacking works by opening the target application in an invisible iframe on an attacker-controlled site and luring a victim to visit the attacker page and interacting with it. By positioning elements over the invisible iframe, a victim can be tricked into triggering malicious or destructive actions in the invisible iframe, while they think they interact with a totally different site altogether. When a victim visits an attacker-controlled site while they are logged into YourSpotify, they can be tricked into performing actions on their YourSpotify instance without their knowledge. These actions include allowing signup of other users or deleting the current user account, resulting in a high impact to the integrity of YourSpotify. This issue has been addressed in version 1.9.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.
