add-ons.org — Vulnerabilities & Security Advisories 18

Add-ons.org serves as a repository for browser extensions and plugins, enabling users to enhance functionality across various platforms. Historically, the platform has been associated with multiple security vulnerabilities, including 18 recorded CVEs, with common classes being remote code execution (RCE), cross-site scripting (XSS), and privilege escalation issues. These vulnerabilities often stem from insufficient input validation and improper permission handling. While no major public security incidents have been widely documented, the consistent presence of CVEs indicates ongoing security challenges. The platform's reliance on third-party contributions increases the risk of malicious or poorly coded extensions being distributed, necessitating robust vetting processes to maintain user safety.
