SourceCVE-2023-49277

dpaste, the popular open source pastebin tool, has a vulnerability that could allow hackers to run malicious code on users’ browsers.

The vulnerability is in the expires parameter of the dpaste API. This allows attackers to perform a “POST Reflected Cross-Site Scripting (XSS) attack”. In a XSS attack, hackers can trick users into clicking a link or submitting a form that includes malicious JavaScript code. This code then gets executed by the user’s browser, potentially accessing data or accounts without permission.

For dpaste users, an attacker could craft a link that exploits this vulnerability to run code when a user visits a page. As dpaste is often used to share code samples, this poses a risk.

Luckily, the developers have released an update to version 3.8 that fixes the problem. All dpaste users are strongly advised to upgrade immediately. If using an earlier version, your site could be vulnerable.

To protect yourself, simply update dpaste to the latest version as soon as possible. This single step will prevent any potential attacks using this vulnerability. Staying on top of software updates is one of the best ways to keep your data and accounts secure online.
