CVE-2018-5180

24
FAUCET Score

CVE-2018-5180 is a use-after-free vulnerability in Mozilla Firefox versions prior to 60, specifically occurring during WebGL operations. This flaw could lead to a potentially exploitable crash due to memory being freed and then reused within a brief window of the same callstack. With a CVSS score of 7.5 (HIGH), it has a network attack vector and low attack complexity, but its impact is limited to availability (denial of service). There is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage.
