Debian-specific Redis Server Lua Sandbox Escape Vulnerability

Redis · Debian-specific Redis Servers

CVSS 10 EPSS 100% no public exploit indexed Fix deadline passed 18 April 2022

What it is

Redis is prone to a (Debian-specific) Lua sandbox escape, which could result in remote code execution.

Why we say that

  • EPSS puts exploitation in the next 30 days at 100%
  • CISA's federal remediation deadline (2022-04-18) has passed
  • CVSS 10 critical
  • Listed in the CISA Known Exploited Vulnerabilities catalogue

Every line above comes from a named public source. Where the evidence is thin, we say so rather than inventing confidence — see methodology.

What to do

Apply updates per vendor instructions.
