CVE-2024-0809

16
FAUCET Score

CVE-2024-0809 describes an inappropriate implementation in Google Chrome's Autofill feature, affecting versions prior to 121.0.6167.85, as well as Fedora Project's Chrome and Fedora. This vulnerability allows a remote attacker to bypass Autofill restrictions through a specially crafted HTML page. With a CVSS score of 4.3 (Medium), it requires user interaction (UI:R) and has a low impact on integrity (I:L), meaning it could lead to unintended data autofill but not data confidentiality or availability compromise. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating a low current threat level.
