Improper state validation in Skia in Google Chrome prior to 153.0.8010.52 allowed a remote attacker to obtain cross-origin data via a crafted HTML page. (Chromium security severity: High)
AnalysisAI
Cross-origin information disclosure in Google Chrome (through the bundled Skia graphics library) affects versions prior to 153.0.8010.52, where improper state validation lets a crafted HTML page cause the renderer to expose data belonging to another origin. Exploitation requires the victim to load an attacker-controlled page (UI:R) and yields only partial confidentiality impact - no code execution, data modification, or denial of service - which is why the CVSS base score is a modest 4.3. …

Vulnerability AssessmentAI
| Exploitation | Requires the victim to visit or load an attacker-controlled web page (UI:R) that contains crafted HTML/content triggering the Skia state-validation flaw. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but low-priority issue: a browser-side cross-origin information disclosure, not memory-corruption RCE. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Vendor-released patch: upgrade Google Chrome to 153.0.8010.52 or later, as documented in the Google Chrome stable channel advisory (https://chromereleases.googleblog.com/2026/09/stable-channel-update-for-desktop_0194356994.html) and tracked in the Chromium issue at https://issues.chromium.org/issues/553130676; the standard auto-update mechanism should pull the build, but verify the installed version via chrome://version and force a manual update or repackage for managed fleets where auto-update is disabled. … Detailed patch versions, workarounds, and compensating controls in full report. |
