Sonatype Nexus Repository Manager Incorrect Access Control
CVE-2019-7238 is a critical-severity vulnerability in Nexus Repository Manager from Sonatype, with a CVSS 3.1 base score of 9.8 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 3.15.0 as the first without the flaw, so updating Nexus Repository Manager to that release or later removes the exposure. CISA added it to the Known Exploited Vulnerabilities catalogue on December 10, 2021, which means attacks have been observed in the wild.
