Sources and claim methodology

  • GitHub security advisorygithub.com
  • Source referencevulncheck.com
Upstream source description

REDAXO core from 5.3.0 before 5.21.4 contains an authentication bypass vulnerability in the structure/history plugin that allows unauthenticated attackers to forge temporary login tokens. Attackers can force the session-tied secret into a predictable state and forge tokens for accounts like admin, gaining backend access and code execution outside live mode.
