CVE-2019-5838

18
FAUCET Score

CVE-2019-5838 is a medium-severity vulnerability affecting Google Chrome prior to version 75.0.3770.80, as well as Debian, Fedora, and OpenSUSE distributions. It involves insufficient policy enforcement in the extensions API, allowing a malicious Chrome extension to bypass file URI restrictions if a user is convinced to install it. The attack requires user interaction (UI:R) and has a low impact on integrity (I:L), with no impact on confidentiality or availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in CISA's KEV catalog, and community discussion and media coverage are minimal.
