misskey-dev — Vulnerabilities & Security Advisories 28

Misskey-dev is the primary development entity behind Misskey, a widely adopted open-source federated microblogging platform. The software facilitates decentralized social networking, allowing users to post content, follow others, and interact across independent instances within the Fediverse. Historically, security audits have identified twenty-eight Common Vulnerabilities and Exposures (CVEs) associated with the codebase. These flaws predominantly involve cross-site scripting (XSS), remote code execution (RCE), and privilege escalation vulnerabilities, often stemming from insufficient input validation or improper access control mechanisms in server-side components. While no catastrophic data breaches have been publicly confirmed as direct results of these specific CVEs, the recurring nature of these issues highlights challenges in maintaining secure code practices within a rapidly evolving open-source project. Continuous patching and community-driven security reviews remain essential for mitigating these risks and ensuring the integrity of the federated network infrastructure.
