The MISP project released version 2.4.110, a maintenance and feature update to the open-source threat intelligence sharing platform. Alongside new capabilities such as expanded misp-modules support for the full MISP standard format, local tagging, and a Norwegian translation, the release addresses a security vulnerability tracked as CVE-2019-12868.
The flaw affected MISP 2.4.109 and stemmed from unsafe use of PHP's file_exists function with user-controlled input, where phar:// URLs could trigger PHP object deserialization leading to remote command execution. Exploitation required site administrator privileges, limiting the practical attack surface to a malicious or compromised super admin account rather than an unauthenticated remote attacker. The issue was reported by Dawid Czarnecki and has been resolved in this release along with several STIX export/import parsing fixes.
Organizations running MISP instances should upgrade to 2.4.110 to remediate the deserialization vulnerability, though the requirement for existing admin-level access reduces the urgency compared to unauthenticated RCE issues. The release also includes numerous quality-of-life and API improvements contributed by the community and partners such as Siemens and SANS.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,433 reports from 149 sources, 661 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
