What the vulnerability does
The wp-twitpic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple parameters of the 'twitpic' shortcode in all versions up to, and including, 1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
wp-twitpic versions 1.0 and earlier contain a cross-site scripting (XSS) vulnerability that allows authenticated users to inject malicious scripts affecting other users. The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Site administrators should update to a version newer than 1.0 when available.
What an attacker can do
Inject malicious scripts that execute in other users' browsers and affect site functionality.
Potential impact on your site
Authenticated users can inject scripts affecting other site visitors and administrators, potentially compromising accounts or site data.
Conditions required to exploit
Attacker must be authenticated as a low-privilege user; no user interaction required from victims.
