Extension distributed over network (AV:N), user must install it (UI:R), no prior auth needed (PR:N), impact is integrity-only navigation bypass with no confidentiality or availability consequence (I:H, C:N, A:N).
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.

Insufficient policy enforcement in Extensions in Google Chrome prior to 151.0.7922.72 allowed an attacker who convinced a user to install a malicious extension to bypass navigation restrictions via a crafted Chrome Extension. (Chromium security severity: Medium)
AnalysisAI
Navigation restriction bypass in Google Chrome's Extensions subsystem affects all desktop versions prior to 151.0.7922.72, enabling an attacker who convinces a user to install a crafted malicious extension to circumvent Chrome's navigation enforcement policies. The CWE-602 root cause indicates client-side policy logic can be subverted by a malicious extension actor, resulting in a high integrity impact with no confidentiality or availability exposure. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the target user to actively install a specifically crafted malicious Chrome extension on a Chrome desktop version prior to 151.0.7922.72 - the CVSS UI:R metric reflects this mandatory social engineering step. … 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:N/I:H/A:N correctly captures network-accessible, low-complexity exploitation requiring user interaction but no prior authentication; the high integrity impact reflects meaningful bypass of navigation controls. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a Chrome extension that exploits the insufficient navigation policy enforcement, then distributes it through a phishing campaign, a deceptive web store listing, or direct sideloading link targeting users of Chrome prior to 151.0.7922.72. Once the victim installs the extension, it bypasses Chrome's navigation restrictions - potentially redirecting users to attacker-controlled pages, circumventing enterprise intranet access controls, or undermining content security policies enforced via navigation rules. … |
| Remediation | Update Google Chrome to version 151.0.7922.72 or later via the stable channel; this is a vendor-released patch as confirmed by the Chrome Releases advisory at https://chromereleases.googleblog.com/2026/07/stable-channel-update-for-desktop_0887107924.html. … Detailed patch versions, workarounds, and compensating controls in full report. |
