AI Insight

LLM-synthesized narrative grounded in this CVE's description and references.

Cross-site scripting vulnerability in Google Chrome 2.x and 3.x before 3.0.195.21 allows remote attackers to inject arbitrary web script via RSS/Atom feeds.

Vulnerability

Cross-site scripting (XSS) vulnerability exists in Google Chrome versions 2.x and 3.x prior to 3.0.195.21. The flaw occurs when the browser renders RSS or Atom feeds with the application/rss+xml content type as XML "active content," allowing injection of arbitrary web script or HTML.

Exploitation

An attacker can exploit this by crafting a malicious RSS or Atom feed containing embedded JavaScript or HTML. When a user using a vulnerable Chrome version accesses the feed, the injected script executes in the context of the feed's origin. No additional authentication or user interaction beyond viewing the feed is required.

Impact

Successful exploitation allows the attacker to execute arbitrary web script or HTML in the user's browser session, potentially leading to data theft, session hijacking, or defacement of the feed content.

Mitigation

The vulnerability is fixed in Google Chrome version 3.0.195.21 and later. Users should upgrade to the latest version. No workarounds are documented in the available references.
