Injection in CSS in Google Chrome prior to 152.0.7977.65 allowed a remote attacker to potentially obtain sensitive information via a crafted HTML page. (Chromium security severity: Medium)
AnalysisAI
CSS injection in Google Chrome prior to version 152.0.7977.65 enables a remote attacker to extract sensitive information from a victim's browser session by delivering a crafted HTML page. The CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N vector confirms unauthenticated network delivery requiring only that the victim navigate to attacker-controlled content, with high confidentiality impact and no integrity or availability consequences. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim user actively navigate to a crafted HTML page controlled by the attacker - this is the UI:R condition that prevents fully automated exploitation. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.5 Medium score reflects the combination of network reachability and high confidentiality impact offset by mandatory user interaction (UI:R), which prevents fully automated, drive-by exploitation without some social engineering step. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts an HTML page embedding CSS injection payloads - for example, attribute selector rules with url() callbacks to an attacker-controlled server - targeting sensitive data values present in the DOM of the page being rendered. The victim is lured to visit the malicious page through a phishing link or malvertising, and the Chrome CSS engine evaluates the injected selectors, triggering network requests that encode and exfiltrate the targeted data to the attacker. … |
| Remediation | Upgrade Google Chrome to version 152.0.7977.65 or later; this is the vendor-confirmed fix per the stable channel update 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. |
