Deeper analysis
Microsoft Edge (Chromium-based) contains a tampering vulnerability tracked as CVE-2023-28301. The flaw is classified under CWE-20 and carries a CVSS 3.1 score of 3.7, reflecting a network-attack vector that requires high attack complexity yet needs no privileges or user interaction to produce limited integrity impact.
An unauthenticated attacker positioned on the network can leverage the issue to tamper with data processed by the browser. Because the attack complexity is rated high, successful exploitation is not straightforward, but the absence of authentication or user-interaction requirements widens the potential attack surface to any reachable Edge instance.
Microsoft has published remediation guidance in its Security Response Center update guide for CVE-2023-28301. Administrators are advised to apply the fixes referenced in that advisory to address the tampering condition.
EPSS for the CVE has remained flat at 0.0585 from disclosure through the present measurement, indicating no material increase in observed exploitation interest.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Security testing and developer training directly verify and enforce proper input validation, reducing exploitability of injection and malformed-data weaknesses.
Security testing and evaluation at multiple SDLC stages directly detects missing or flawed input validation, with the required remediation process ensuring fixes are applied.
Directly implements checks on information inputs to reject invalid data before processing.
Spam protection mechanisms perform filtering and detection on inbound/outbound messages, directly compensating for missing or weak input validation of unsolicited content.
