AVAST — Vulnerabilities & Security Advisories 23

AVAST operates primarily as a provider of consumer cybersecurity software, offering antivirus protection, network security tools, and privacy utilities to millions of users globally. Its extensive software portfolio, which includes desktop applications and browser extensions, has historically been susceptible to a variety of vulnerability classes, including remote code execution (RCE), cross-site scripting (XSS), and privilege escalation flaws. These weaknesses often stem from complex codebases and third-party dependencies within its endpoint protection agents. Notable security incidents include the 2020 data breach where user data from its subsidiary, Jumpshot, was exposed, raising significant privacy concerns. With 24 recorded CVEs, the company faces ongoing challenges in maintaining robust security hygiene across its diverse product ecosystem, requiring continuous patching and rigorous code audits to mitigate risks associated with its widespread deployment in consumer environments.
