Operation on a resource after expiration or release in Microsoft Edge (Chromium-based) allows an unauthorized attacker to disclose information over a network.
AnalysisAI
Information disclosure in Microsoft Edge (Chromium-based) prior to version 150.0.4078.48 enables network-based attackers to expose sensitive browser data through a use-after-resource condition (CWE-672). Exploitation requires user interaction and high attack complexity, but the changed scope (S:C) indicates the flaw breaches browser isolation boundaries, yielding high confidentiality impact. …

Vulnerability AssessmentAI
| Exploitation | Active user interaction is required: the victim must visit an attacker-controlled or compromised webpage (UI:R). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 6.1 Medium score reflects a meaningful but constrained threat profile. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker hosts a crafted webpage that triggers a specific resource-lifecycle timing condition in the Chromium-based rendering engine; when a victim running a vulnerable version of Edge visits the page, the flaw causes the engine to operate on an expired or freed resource. Successful exploitation - requiring the attacker to correctly engineer the race or timing condition - allows the attacker to read sensitive browser memory, potentially including session tokens, authentication cookies, or cross-origin page content, which is exfiltrated over the network. |
| Remediation | Vendor-released patch: Microsoft Edge (Chromium-based) 150.0.4078.48. … Detailed patch versions, workarounds, and compensating controls in full report. |
