CVE-2018-7726

22
FAUCET Score

CVE-2018-7726 describes a denial-of-service vulnerability in ZZIPlib 0.13.68, specifically within the __zzip_parse_root_directory function, which can be triggered by a specially crafted zip file. This medium-severity vulnerability (CVSS 6.5) requires user interaction (UI:R) and network access (AV:N) to exploit, leading to a high impact on availability (A:H) due to a bus error. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting it is not widely targeted.
