CVE-2025-8343

CVE-2025-8343 is a critical path traversal vulnerability affecting viglet shio versions up to 0.3.8, specifically within the shStaticFilePreUpload function. This flaw allows an unauthenticated attacker to remotely manipulate the fileName argument, potentially leading to unauthorized access, modification, or deletion of arbitrary files on the system. With a CVSS score of 9.8 (CRITICAL), it presents a severe risk due to its network-based attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability. While the exploit has been publicly disclosed, there is currently no evidence of active exploitation, nor are there readily available Metasploit, Nuclei, or ExploitDB modules, and community discussion remains minimal.
