What the vulnerability does
The Bitly's plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wpbitly' shortcode in all versions up to, and including, 2.7.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Bitly's WordPress Plugin versions 2.7.1 and earlier contain a stored cross-site scripting (XSS) vulnerability. An authenticated user with low privileges can inject malicious scripts that execute in the browsers of other site visitors, including administrators. The vulnerability affects the plugin's handling of user input and can impact site security and user data.
What an attacker can do
Inject malicious scripts that run in other users' browsers, potentially stealing session tokens or admin credentials.
Potential impact on your site
Attackers with basic WordPress access can compromise admin accounts and take control of your site.
Conditions required to exploit
Attacker must have a low-privilege WordPress account (e.g., subscriber or contributor role).
