Improper neutralization of parameter/argument delimiters in Microsoft Edge (Chromium-based) allows an unauthorized attacker to execute code over a network.
AnalysisAI
Parameter/argument delimiter injection in Microsoft Edge (Chromium-based) enables network-based code execution by an unauthenticated remote attacker who can induce a user to interact with malicious content. The flaw, classified under CWE-141, stems from insufficient sanitization of delimiter characters in parameter or argument handling within the browser, potentially allowing injected values to alter command or function execution semantics. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | User interaction is required - the target must actively visit a malicious web page, click a crafted link, or otherwise interact with attacker-controlled content; passive drive-by exploitation without any user action is not supported by the UI:R CVSS metric. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 5.4 (Medium) reflects a meaningful but constrained risk profile: the attack vector is network (AV:N) and complexity is low (AC:L), but user interaction is required (UI:R), the scope is unchanged (S:U), and impacts are limited to low confidentiality and low integrity (C:L/I:L/A:N). … 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 | Apply the vendor-released patch immediately via Microsoft Edge's built-in update mechanism or through Microsoft Update/WSUS for enterprise environments; the exact patched build version should be confirmed at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-66323. … Detailed patch versions, workarounds, and compensating controls in full report. |
