CVE-2025-61882: Oracle E-Business Suite Unspecified Vulnerability

Should you act?

Exploited: patch now if you run it

CISA has confirmed exploitation in the wild. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• Yes, if you run Oracle E-Business Suite. CISA added this CVE to its Known Exploited Vulnerabilities catalog on 2025-10-06, which means there is reliable evidence of exploitation in the wild. US federal agencies must remediate by 2025-10-27; treat that as the outer limit, not the target. CISA also lists it as known to be used in ransomware campaigns.
• EPSS 99.7%, percentile 100.0: FIRST’s model estimates a 99.7% chance of exploitation activity in the next 30 days, higher than 100.0% of all scored CVEs (very high). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Editorial verdict: Act now. Oracle EBS CVE-2025-61882: Cl0p Zero-Day Data Theft — Any internet-reachable Oracle EBS 12.2.x server that missed the October 2025 alerts should be treated as compromised until a hunt proves otherwise.
