[UPDATE] [hoch] PostgreSQL: Mehrere Schwachstellen

CSIRTS triage

What

An attacker can exploit multiple vulnerabilities in PostgreSQL to execute arbitrary program code, carry out a denial-of-service attack, disclose information, manipulate files, conduct an SQL injection attack, and bypass security measures.

Who is affected

Deployments of PostgreSQL with the affected versions.

Urgency

Remediation is urgent due to the high severity and potential for remote code execution and denial of service.

Action

Apply the latest patches for PostgreSQL.

Exploitation outlook

EPSS (FIRST.org) estimates each CVE’s probability of exploitation in the next 30 days — here is the CSIRTS.com read on those numbers.

• Low exploitation riskCVE-2026-64720.16% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 5% of all EPSS-scored CVEs.
• Moderate exploitation riskCVE-2026-64731.0% 30-day exploitation probability. Patch within normal cadence, watch for KEV listing. Riskier than 61% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-64740.21% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 12% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-64750.32% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 25% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-64760.29% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 21% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-64770.45% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 38% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-64780.56% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 45% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-64790.47% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 39% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-65750.21% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 11% of all EPSS-scored CVEs.
• Low exploitation riskCVE-2026-66370.37% 30-day exploitation probability — currently an unlikely target, but scores change as exploit code circulates. Riskier than 30% of all EPSS-scored CVEs.
