AI Analysis

Impact

The vulnerability remains a cross‑site scripting flaw in Chrome’s ReadingMode module that enables a remote attacker to craft an HTML page which, when opened in ReadingMode, can spoof user interface elements. It is still classified as CWE‑79 and CWE‑825.

Affected Systems

The vulnerability affects Google Chrome browsers earlier than version 156.0.8078.47.

Risk and Exploitability

Based on the description, the CVSS score of 8.8 classifies it as high severity. The EPSS score is below 1%, indicating a low probability of exploitation, and it is not listed in the CISA KEV catalog, suggesting limited publicly known exploitation. Based on the description, the likely attack vector is a remote web page rendered in ReadingMode, implying that any user who opens a malicious link or downloads a crafted HTML page could be compromised, provided they run Chrome with ReadingMode enabled.
