U.S. CISA adds PaperCut NG/MF flaws to its Known Exploited Vulnerabilities catalog
CISA added two actively exploited PaperCut NG/MF pre-auth flaws to the KEV catalog; federal agencies must patch by September 14.
CISA added CVE-2026-81578 (CVSS 8.8, missing authentication for critical function) and CVE-2026-82078 (CVSS 9.4, unsafe reflection) in PaperCut NG/MF to its Known Exploited Vulnerabilities catalog. Huntress confirmed active pre-authentication RCE exploitation in two customer environments and reproduced the full chain against a clean PaperCut NG 25.0.11 server, chaining the auth bypass into unsafe Java class loading for SYSTEM-level execution. About 47% of roughly 2,500 tracked PaperCut installs still run version 23 or earlier with no patch available, and observed attacker activity was limited to system discovery commands.

U.S. CISA adds a Ray-Project Ray flaw to its Known Exploited Vulnerabilities catalog
CISA added actively exploited Ray RCE flaw CVE-2025-62593 (CVSS 9.4) to its KEV catalog, ordering federal agencies to patch by August 20, 2026.
CISA added CVE-2025-62593 (CVSS 9.4), a critical remote code execution flaw in the Ray AI compute engine, to its Known Exploited Vulnerabilities catalog with a due date of August 20, 2026. Versions before 2.52.0 relied on a User-Agent header check to guard the dashboard/API, which combined with DNS rebinding allows arbitrary code execution on developers' machines via malicious websites or ads. Aviatrix's analysis describes privilege escalation, lateral movement, command and control, and data exfiltration following exploitation. Federal civilian agencies must remediate under BOD 22-01; the flaw affects Firefox and Safari.

U.S. CISA adds Gitea flaw to its Known Exploited Vulnerabilities catalog
CISA added the actively exploited Gitea RCE flaw CVE-2026-60004 (CVSS 9.8) to its KEV catalog, with federal patching due by August 28, 2026.
CISA added CVE-2026-60004, a critical remote code execution flaw in Gitea (CVSS 9.8), to its Known Exploited Vulnerabilities catalog. The flaw affects Gitea versions since 1.17, fixed in 1.27.1, and lets attackers with repository write access execute shell commands via the diffpatch API and Git hooks. Open registration allows unauthenticated attackers to create accounts and exploit exposed instances, with a reported attack deploying a cryptocurrency-miner-like payload.

U.S. CISA adds maximum-severity Oracle flaw to its Known Exploited Vulnerabilities catalog
CISA added actively exploited CVE-2026-21962, a CVSS 10.0 unauthenticated flaw in Oracle HTTP Server and WebLogic Proxy Plug-in, to KEV with an August 27 deadline.
CISA added CVE-2026-21962 (CVSS 10.0), an improper access control vulnerability in Oracle HTTP Server and the Oracle WebLogic Server Proxy Plug-in, to its Known Exploited Vulnerabilities catalog and ordered federal agencies to remediate by August 27, 2026. The unauthenticated flaw allows remote attackers with network access to create, delete, or modify critical data, potentially gain broad access, and cause a scope change to other systems; affected versions are 12.2.1.4.0, 14.1.1.0.0 and 14.1.2.0.0. CloudSEK honeypot data from January-February 2026 showed widespread exploitation of the flaw alongside older WebLogic RCEs including CVE-2020-14882/14883, CVE-2020-2551, and CVE-2017-10271.
