Insufficient data validation in DevTools in Google Chrome prior to 150.0.7871.47 allowed a remote attacker who convinced a user to engage in specific UI gestures to leak cross-origin data via a crafted HTML page. (Chromium security severity: Low)
AnalysisAI
Cross-origin data leak in Google Chrome DevTools prior to version 150.0.7871.47 exposes sensitive information from foreign origins when a victim visits a crafted HTML page and performs attacker-directed UI gestures. The CVSS vector (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) confirms high confidentiality impact with no integrity or availability consequences. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires: (1) the victim runs Google Chrome prior to version 150.0.7871.47; (2) the victim navigates to a crafted HTML page controlled by the attacker; (3) the victim performs specific UI gestures on or within that page - this is a confirmed prerequisite per the CVE description and reflected in CVSS UI:R. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | CVSS 6.5 Medium (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N) reflects a network-reachable, low-complexity attack path with high confidentiality impact, but the required user interaction (UI:R - specific UI gestures) is a meaningful constraint that prevents fully silent drive-by exploitation. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious HTML page and distributes it via phishing or a compromised website, then relies on social engineering to induce the victim into performing specific UI gestures - such as clicking particular elements or interacting with browser controls - while the page is open. Through the DevTools validation gap, the attacker's page reads cross-origin data the victim's browser can access (e.g., content from an authenticated session on another tab or origin), exfiltrating it to an attacker-controlled endpoint. … |
| Remediation | Update Google Chrome to version 150.0.7871.47 or later, which is the vendor-released patch addressing this vulnerability (stable channel update, https://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html). … Detailed patch versions, workarounds, and compensating controls in full report. |
