What is CVE-2022-46908?

SQLite versions up to 3.40.0 exhibit a flaw when executing untrusted command-line interface (CLI) scripts while using the --safe option. The azProhibitedFunctions protection mechanism is not correctly enforced, potentially allowing unrestricted user-defined functions (UDFs) to be executed, such as WRITEFILE. This oversight can lead to unintended interactions with the file system, posing a risk for data leakage or modification.
