This allows an attacker to input excessively large strings of numbers (e.g., "9999999999999999999999"), which pass the regex check but when passed to `as.integer()` are coerced to `NA`. This causes the script to crash or behave unexpectedly down the line since `NA` is not handled. +**Learning:** Using overly permissive unbounded regex checks (like `^[0-9]+$`) for specific menu selections fails to protect against bounds limits of integer data types. Strict matching to exact required values is necessary. +**Prevention:** Strictly match against exact expected values (e.g., `grepl("^[12]$", n)`) rather than unbounded digit classes. This ensures that the input is exactly one of the permitted options before coercion to integer. + ## 2024-07-12 - Fix missing parameter validations **Vulnerability:** Unvalidated inputs passed to `if()` statements can cause process crashes (`condition has length > 1`) or unexpected coercion vulnerabilities. **Learning:** In R, optional boolean parameters that default to `NULL` should be validated using explicit runtime type validation (e.g., `if (!is.null(flag) && (!is.logical(flag) || length(flag) != 1 || is.na(flag)))`). diff --git a/DESCRIPTION b/DESCRIPTION index f31d3e1..c90753c 100644 --- a/DESCRIPTION +++ b/DESCRIPTION @@ -10,7 +10,7 @@ Description: Automates fixed item parameter linking for test linking under the item response theory paradigm using mirt package estimates.
