Severity by source
AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N
Race condition exploitation requires precise timing alignment beyond attacker control, justifying AC:H; no privileges needed and confidentiality impact is high from cross-origin data leakage.

Race in Storage 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: Low)
AnalysisAI
Cross-origin data leakage in Google Chrome's Storage component prior to version 150.0.7871.47 enables remote attackers to read data belonging to a different origin by exploiting a race condition triggered via a crafted HTML page. The Chromium security team internally rated this as Low severity - a notable contrast to the CVSS 6.5 score reflecting High confidentiality impact - suggesting the practical exploitation window or data exposure scope is constrained in real-world conditions. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim running Google Chrome prior to 150.0.7871.47 to actively visit a crafted HTML page under attacker control - user interaction is mandatory (confirmed by UI:R in the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) signals a network-reachable, unauthenticated flaw with High confidentiality impact but requires user interaction, capping the score at 6.5. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sets up a malicious website containing a crafted HTML page engineered to trigger a precise race condition in Chrome's Storage component while the victim's browser has active cross-origin content loaded. When the victim navigates to the attacker's page in an unpatched Chrome browser, the race window allows the malicious page to read storage state - potentially including session identifiers or sensitive cached data - from a different origin. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, which contains the vendor-released patch for this race condition per the Chromium stable channel advisory at https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
