Is CVE-2025-48928 being exploited?

Yes. CVE-2025-48928 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.

How severe is CVE-2025-48928?

CVE-2025-48928 is rated Medium with a CVSS score of 4.0. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2025-48928?

Not known from our data. No patch reference has been recorded for CVE-2025-48928, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written.
