Inappropriate implementation in Paint in Google Chrome prior to 151.0.7922.72 allowed a remote attacker to leak cross-origin data via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Cross-origin data leakage in Google Chrome's Paint subsystem (all versions prior to 151.0.7922.72) allows a remote attacker to read data belonging to other web origins by delivering a crafted HTML page to a victim. The root cause is an origin validation error (CWE-346) in the Paint rendering component, permitting cross-origin information to surface where it should be isolated. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim to actively navigate to or be redirected to an attacker-controlled HTML page (UI:R) using Google Chrome prior to version 151.0.7922.72. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 3.1 scores this at 4.3 (Medium) with a vector of AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N, reflecting a network-reachable, low-complexity flaw that requires no privileges but does require user interaction, with only partial confidentiality impact and no integrity or availability consequences. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page that abuses the Paint origin validation flaw to read data rendered from a cross-origin resource loaded in the victim's Chrome browser. The attacker distributes the page via phishing email, malicious advertisement, or compromised website and waits for a target running an unpatched Chrome version to visit it, after which cross-origin data is exfiltrated to the attacker's server. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later, which resolves this vulnerability per the vendor's stable channel advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
