Browse all 2185 CVE security advisories affecting Mozilla. AI-powered Chinese analysis, POCs, and references for each vulnerability.

Mozilla operates as a non-profit organization primarily known for developing the Firefox web browser and maintaining the Gecko rendering engine. Its software portfolio serves millions of users globally, focusing on open-source web technologies and privacy-centric browsing solutions. Historically, the codebase has been susceptible to a wide array of vulnerabilities, including remote code execution, cross-site scripting, and memory corruption issues such as buffer overflows. These flaws often stem from complex JavaScript engines and network stack implementations. While Mozilla maintains a robust security response team and regularly issues patches, the sheer volume of recorded Common Vulnerabilities and Exposures highlights the challenges inherent in maintaining large-scale, cross-platform applications. The organization continues to prioritize security audits and community-driven bug bounty programs to mitigate risks associated with its extensive feature set and widespread adoption.
