  "details": "Parse Server before 4.10.0 was affected by a supply chain incident in which incorrect version tags were pushed to the official repository pointing to an unreviewed personal fork of a contributor with write access. No releases were published with these tags; a project was exposed only if it defined a git-based dependency referencing one of the affected tags (for example, parse-server#4.9.3). The code behind the tags was not reviewed or approved, and although no malicious code was identified, the introduction of security vulnerabilities could not be ruled out.",
