common questions

Is CVE-2025-65077 being exploited?

Not confirmed. CVE-2025-65077 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 0.64% probability of exploitation in the next 30 days.

How severe is CVE-2025-65077?

CVE-2025-65077 is rated High with a CVSS score of 8.8. 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-2025-65077?

Not known from our data. No patch reference has been recorded for CVE-2025-65077, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written.
