WordPress InPost Gallery <2.1.4.1 - Local File Inclusion

id: CVE-2022-4063

info:
  name: WordPress InPost Gallery <2.1.4.1 - Local File Inclusion
  author: theamanrawat
  severity: critical
  description: |
    WordPress InPost Gallery plugin before 2.1.4.1 is susceptible to local file inclusion. The plugin insecurely uses PHP's extract() function when rendering HTML views, which can allow attackers to force inclusion of malicious files and URLs. This, in turn, can enable them to execute code remotely on servers.
  impact: |
    The vulnerability allows an attacker to read arbitrary files on the server, potentially exposing sensitive information or executing malicious code.
  remediation: Fixed in version 2.1.4.1.
