CVE-2024-49400: Facebook Tacquito

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

Tacquito prior to commit 07b49d1358e6ec0b5aa482fcd284f509191119e2 was not properly performing regex matches on authorized commands and arguments. Configured allowed commands/arguments were intended to require a match on the entire string, but instead only enforced a match on a sub-string. That would have potentially allowed unauthorized commands to be executed.
