octobercms — Vulnerabilities & Security Advisories 39

OctoberCMS is a Laravel-based content management system designed for developers seeking a flexible, self-hosted platform for building custom web applications. Its architecture relies heavily on the Laravel framework, which influences its security posture and dependency management. Historically, the platform has been associated with numerous vulnerabilities, including remote code execution, cross-site scripting, and privilege escalation flaws, often stemming from improper input validation or insecure deserialization practices. With 39 recorded CVEs, many issues relate to outdated dependencies or misconfigured plugins rather than core framework weaknesses. Notable incidents frequently involve plugin-specific exploits that allow attackers to bypass authentication or execute arbitrary commands. The security landscape is further complicated by the fragmented nature of its plugin ecosystem, where third-party extensions may introduce unpatched risks. Users must prioritize regular updates and strict plugin vetting to mitigate these persistent threats inherent in its modular design.
