Side-channel information leakage in Paint in Google Chrome prior to 150.0.7871.47 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Side-channel cross-origin data leakage in Google Chrome's Paint rendering component (all versions prior to 150.0.7871.47) allows remote attackers to infer sensitive content belonging to other origins by enticing a victim to visit a crafted HTML page. The vulnerability exploits a weakness in the Paint subsystem's rendering pipeline (CWE-1300: Improper Protection of Physical Side Channels), enabling an attacker page to observe rendering state or timing variations and reconstruct protected cross-origin data. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim user to actively visit an attacker-controlled HTML page in an unpatched version of Google Chrome (prior to 150.0.7871.47) on a desktop platform. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 6.5 (Medium) with vector AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N reflects a high confidentiality impact accessible over the network with no attacker privileges, but critically gated by required user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted HTML page that embeds or references cross-origin resources and uses JavaScript to observe timing or state variations in Chrome's Paint rendering subsystem while those resources are rendered. When a victim visits this page in an unpatched Chrome browser, the side-channel allows the attacker script to infer pixel-level or structural content belonging to a different origin - potentially including session-authenticated pages loaded in adjacent tabs or frames. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released patch for this vulnerability per the Chrome Stable Channel Update advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
