HIGHCVSS 8.1/10EPSS 1.57%

Last modified

CVE-2020-25694 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in-the-middle attack, or the ability to observe clear-text transmissions, could exist. EPSS estimates a 1.57% chance of exploitation in the next 30 days.
