CWE-79

A cross-site scripting issue has been discovered in GitLab CE/EE affecting all versions prior to 15.3.5, 15.4 prior to 15.4.4, and 15.5 prior to 15.5.2. It was possible to exploit a vulnerability in setting the labels colour feature which could lead to a stored XSS that allowed attackers to perform arbitrary actions on behalf of victims at client side.

If an attacker can control a script that is executed in the victim’s browser, then they can typically fully compromise that user. Amongst other things, the attacker can: Perform any action within the application that the user can perform. View any information that the user is able to view. Modify any information that the user is able to modify. Initiate interactions with other application users, including malicious attacks, that will appear to originate from the initial victim user.

The Appfire Jira Misc Custom Fields (JMCF) app 2.4.6 for Atlassian Jira allows XSS via a crafted project name to the Add Auto Indexing Rule function.

HTML injection attack is closely related to Cross-site Scripting (XSS). HTML injection uses HTML to deface the page. XSS, as the name implies, injects JavaScript into the page. Both attacks exploit insufficient validation of user input.

The WP Contact Slider WordPress plugin before 2.4.8 does not sanitize and escape its settings, allowing high privilege users such as admin to perform cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.

Softr v2.0 was discovered to contain a Cross-Site Scripting (XSS) vulnerability via the First Name parameter under the Create A New Account module. This vulnerability allows attackers to execute arbitrary web scripts or HTML via a crafted payload.
