The MISP project released version 2.4.142, addressing a security issue tracked as CVE-2021-31780 that could cause sharing groups on synced attributes to become misaligned, potentially exposing shared threat data to unintended audiences. The advisory urges all MISP instance administrators to update to remediate the issue.

Server sync rule management was also reworked with a friendlier UI and automatic tag retrieval for pull filters. The release further includes new dashboard widgets for usage statistics and updates to misp-objects, misp-taxonomies, and misp-galaxy, notably expanding the Ransomware galaxy to over 1600 documented ransomware families.
