The following cybersecurity agencies coauthored this joint Cybersecurity Advisory (hereafter collectively referred to as the authoring agencies):

This advisory provides details, collected and compiled by the authoring agencies, on the Common Vulnerabilities and Exposures (CVEs) routinely and frequently exploited by malicious cyber actors in 2023 and their associated Common Weakness Enumerations (CWEs). Malicious cyber actors exploited more zero-day vulnerabilities to compromise enterprise networks in 2023 compared to 2022, allowing them to conduct operations against high priority targets.
The authoring agencies strongly encourage vendors, designers, developers, and end-user organizations to implement the following recommendations, and those found within the Mitigations section of this advisory, to reduce the risk of compromise by malicious cyber actors.
