Network-delivered, no attacker privileges, one user interaction required; only low confidentiality impact from origin bypass with no write or availability effect.
vuln.today treats the vendor’s rating as authoritative. A higher third-party CVSS (e.g. CISA-ADP) is shown for transparency but does not drive the headline severity.

Incorrect authorization in Loader in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to bypass web origin policy via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
Web origin policy bypass in Google Chrome's Loader component (all versions prior to 152.0.7977.65) enables remote unauthenticated attackers to read limited cross-origin data by luring a user to a crafted HTML page. The flaw stems from incorrect authorization (CWE-863) in how the Loader enforces origin boundaries, allowing an attacker-controlled page to extract content from another origin the victim is browsing. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a victim user to actively visit an attacker-controlled or compromised HTML page - user interaction is mandatory (UI:R per CVSS), and passive network-side exploitation is not possible. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.3 Medium rating is internally consistent: AV:N (network-delivered), AC:L (no special conditions), PR:N (no attacker privileges needed), UI:R (victim must visit the crafted page), S:U (no scope change beyond the affected browser session), C:L (limited cross-origin data read), I:N and A:N (no write or availability impact). … 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 | Upgrade Google Chrome to version 152.0.7977.65 or later, the vendor-confirmed fix per the Chrome stable channel advisory at https://chromereleases.googleblog.com/2026/08/stable-channel-update-for-desktop_0256176589.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
