Impact

Information leak in Animation in Google Chrome before 156.0.8078.47 allows a remote attacker to craft a malicious web page that leaks sensitive information. The flaw is classified as Information Exposure (CWE‑200).

Affected Systems

Google Chrome, any version before 156.0.8078.47. The issue was fixed in the stable release 156.0.8078.47.

Risk and Exploitability

The attack requires a victim to load a maliciously crafted web page; no local privileges are needed. Chromium Security rated the severity as Medium with a CVSS score of 8.8, and the flaw is not currently listed in CISA’s KEV catalog. No publicly available exploits are reported, and the EPSS score is less than 1%, indicating a low exploitation probability. Because the vulnerability bypasses a core browser security boundary, it poses a significant threat if visitors are exposed to attacker‑controlled web content.
