CVE-2022-0951

22
FAUCET Score

CVE-2022-0951 describes a file upload restriction bypass vulnerability in star7th/showdoc versions prior to 2.10.4, which can lead to a stored Cross-Site Scripting (XSS) attack. This medium-severity vulnerability (CVSS 6.1) allows an unauthenticated attacker to execute arbitrary scripts in a victim's browser if they interact with a maliciously uploaded file. While the attack complexity is low, it requires user interaction for successful exploitation, potentially leading to limited impact on confidentiality and integrity. There is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
