Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the victim to actively visit a crafted HTML page in Google Chrome prior to version 150.0.7871.47 - user interaction (UI:R) is a mandatory prerequisite and the single most significant limiting factor. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 5.4 Medium score is driven by AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N - exploitable over the network with low complexity and no authentication, but requiring victim interaction (visiting a crafted page) and producing only limited, same-scope impact. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts an HTML page containing specially structured HTML tags or attributes designed to trigger the HTMLParser's flawed parsing logic. When a victim using an unpatched Chrome version navigates to this page - via a phishing link, malicious advertisement, or compromised website - the parser misprocesses the input and the injected script executes within the browser's page context, allowing the attacker to harvest cookies, capture keystrokes, or perform actions on the victim's behalf on the affected origin. … |
| Remediation | The primary fix is to update Google Chrome to version 150.0.7871.47 or later, confirmed as the vendor-released patch per the Chrome Releases advisory at http://chromereleases.googleblog.com/2026/06/stable-channel-update-for-desktop_0175352312.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
