Descripción técnica

TripleLift's ad rendering script (video-bundle.js) contains a DOM-based cross-site scripting vulnerability that allows unauthenticated attackers to execute arbitrary JavaScript in a publisher's domain by sending crafted postMessage payloads without origin validation. Attackers can cause a victim to visit an attacker-controlled page that sends malicious postMessage events to a publisher page running the ad script, enabling session hijacking and unauthorized DOM manipulation.

———Allure 2 is the version 2.x branch of Allure Report, a multi-language test reporting tool. Prior to 2.39.0, the ansi.js helper at allure-generator/src/main/javascript/helpers/ansi.js passes attacker-influenced statusMessage and statusTrace values through AnsiToHtml without HTML escaping and wraps the result in Handlebars SafeString, disabling template auto-escaping in allure-generator/src/main/javascript/blocks/status-details/status-details.hbs. JunitXmlPlugin.java can populate these fields directly from crafted JUnit XML failure messages and traces, and equivalent input flows exist in the TRX, xUnit XML, xctest, and Allure1 and Allure2 plugins. When a user views the affected status details, unescaped markup executes arbitrary JavaScript in the report origin, which can expose report data and compromise sessions associated with that origin. This is an incomplete-fix case because PR 3271 escaped link helpers but did not address the ANSI helper. This issue is fixed in version 2.39.0.7h CVE-2026-541815.4 MED

———backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, src/resources/views/crud/columns/color.blade.php inverts the escaped and raw rendering branches controlled by $column['escaped'], which defaults to true, causing $column['text'] to be rendered unescaped by default. An attacker who can store an unsanitized value in a color column can execute script in the browser of a user who views the CRUD list, including an administrator, with access to the victim's session-backed application capabilities. Exploitation requires write access to the stored color value and a victim viewing the list. This issue is fixed in versions 6.8.14 and 7.0.38.7h CVE-2026-540877.6 ALT

———EasyAdmin is a fast and modern admin generator for Symfony applications. From 5.0.0 until 5.0.13, FileField and ImageField can accept browser-executable uploads while templates/crud/field/file.html.twig links to stored files for inline same-origin rendering without a download attribute or Content-Disposition attachment header. When uploads are stored under the public web root, an attacker with access to an affected form can upload HTML through FileField or SVG through ImageField, and JavaScript executes in an authenticated administrator's origin when the file is opened from the backend. Exploitation requires a privilege gap between the uploader and viewer. The issue can expose session or CSRF tokens and enable privilege escalation, but does not permit PHP or PHTML code execution because Symfony guessExtension does not produce those stored extensions. This issue is fixed in version 5.0.13.7h CVE-2026-909438.7 ALT

———parallax filament-comments through 3.0.0 contains a stored cross-site scripting vulnerability in comment body rendering that allows authenticated panel users to inject malicious scripts. Attackers can store XSS payloads in comment bodies that execute in the browsers of other users viewing those comments, including administrators, enabling session token theft and unauthorized actions.9h CVE-2026-907954.3 MED

———A vulnerability was determined in itsourcecode Loan Management System 1.0. The impacted element is an unknown function of the file navbar.php. Executing a manipulation of the argument page can lead to cross site scripting. It is possible to launch the attack remotely. The exploit has been publicly disclosed and may be utilized.9h CVE-2026-41036.4 MED

—

———Insufficient HTML sanitization in the Publisher Portal and Developer Portal allows untrusted user input to be rendered without proper encoding or neutralization. This enables the injection and execution of malicious JavaScript when affected API documents are viewed. Successful exploitation may result in the execution of malicious scripts within the user's browser context when viewing API documentation. Users with permissions to access the API documentation through these portals may be impacted, potentially allowing attackers to perform actions on behalf of the user, depending on their session privileges.9h
