Furthermore, the fix adds existential checks on `oldFormModel` and `newFormModel` immediately following their `try()` estimation blocks to ensure failures fast-fail cleanly rather than crashing internally on missing property access (`@OptimInfo`). Test cases were updated to reflect these security restrictions. --- .jules/sentinel.md | 8 +++++++ R/aFIPC.R | 27 ++++++++++++++++++++++ tests/testthat/test-autoFIPC.R | 41 ++++++++++++++++++++++++++++++---- 3 files changed, 72 insertions(+), 4 deletions(-) diff --git a/.jules/sentinel.md b/.jules/sentinel.md index 75b4a40..3fca73c 100644 --- a/.jules/sentinel.md +++ b/.jules/sentinel.md @@ -17,3 +17,11 @@ 1.

After the loop, verify success and fail securely with an explicit error (`if (!exists('model')) stop(...)`) to prevent unhandled exceptions downstream. + +## 2024-07-05 - Missing Input Validation +**Vulnerability:** The `autoFIPC` function lacked explicit input validation for core arguments like `newformXData`, `oldformYData`, `newformCommonItemNames`, and `itemtype`. When unexpected types (e.g. integer `1` instead of a data structure, or an array for `itemtype`) were provided, the errors propagated dynamically causing unhandled downstream exceptions or potential state leaks depending on internal implementations (like `mirt` and `try` blocks capturing objects unexpectedly). Furthermore, if the base model estimation `try(mirt(...))` entirely failed to produce a model object, the code would later crash when trying to access `@OptimInfo`, leading to untracked exceptions. +**Learning:** In dynamically typed environments like R, trusting user inputs without explicit runtime validation boundaries allows malformed types to flow deeply into internal logic. This can result in obscure failure modes, leakage of unhandled stack exceptions, or unpredictable behavior across statistical dependencies. +**Prevention:** +1. Always enforce explicit boundary checks on public-facing functions (e.g., verifying `is.data.frame`, `is.matrix`, or custom class types). +2. Fail fast and securely with explicit "Security Error" messages when the data contract is violated, before passing data to third-party statistical engines. +3. When using `try()` to swallow errors on initial setup, immediately verify the expected object (`exists("model")`) was actually created before accessing its slots or attributes. diff --git a/R/aFIPC.R b/R/aFIPC.R index 2e5ac4a..83d4a01 100644 --- a/R/aFIPC.R +++ b/R/aFIPC.R @@ -53,6 +53,25 @@ autoFIPC <- try(invisible(gc()), silent = T) # garbage cleaning + # Input validation - Security Enhancement + if (!is.data.frame(newformXData) && !is.matrix(newformXData) && !inherits(newformXData, "SingleGroupClass")) { + stop("Security Error: newformXData must be a data.frame, matrix, or mirt model (SingleGroupClass)") + } + if (!is.data.frame(oldformYData) && !is.matrix(oldformYData) && !inherits(oldformYData, "SingleGroupClass")) { + stop("Security Error: oldformYData must be a data.frame, matrix, or mirt model (SingleGroupClass)") + } + + if (!is.character(newformCommonItemNames) && !is.factor(newformCommonItemNames)) { + stop("Security Error: newformCommonItemNames must be a character vector") + } + if (!is.character(oldformCommonItemNames) && !is.factor(oldformCommonItemNames)) { + stop("Security Error: oldformCommonItemNames must be a character vector") + } + + if (!is.character(itemtype) || length(itemtype) != 1) { + stop("Security Error: itemtype must be a single character string") + } + # checking configure if (length(newformCommonItemNames) != length(oldformCommonItemNames)) { stop('Common Items are not equal') @@ -182,6 +201,10 @@ autoFIPC <- ) } + if (!exists("oldFormModel")) { + stop("Security Error: Initial estimation of oldFormModel completely failed") + } + if (tryFitwholeOldItems == T) { if ( !oldFormModel@OptimInfo$secondordertest && @@ -396,6 +419,10 @@ autoFIPC <- ) } + if (!exists("newFormModel")) { + stop("Security Error: Initial estimation of newFormModel completely failed") + } + if (tryFitwholeNewItems) { if ( !newFormModel@OptimInfo$secondordertest && diff --git a/tests/testthat/test-autoFIPC.R b/tests/testthat/test-autoFIPC.R index ab35135..82ff1ef 100644 --- a/tests/testthat/test-autoFIPC.R +++ b/tests/testthat/test-autoFIPC.R @@ -2,8 +2,8 @@ test_that("autoFIPC raises error in non-interactive session for inputs", { # interactive() should be FALSE by default in testthat environments expect_error( aFIPC::autoFIPC( - newformXData = 1, - oldformYData = 2, + newformXData = data.frame(A=1), + oldformYData = data.frame(A=2), newformCommonItemNames = c('A'), oldformCommonItemNames = c('A') ), @@ -14,8 +14,8 @@ test_that("autoFIPC raises error in non-interactive session for inputs", { test_that("autoFIPC does not implicitly approve supplied common items", { expect_error( aFIPC::autoFIPC( - newformXData = 1, - oldformYData = 2, + newformXData = data.frame(A=1), + oldformYData = data.frame(A=2), newformCommonItemNames = c('A'), oldformCommonItemNames = c('A'), confirmCommonItems = FALSE @@ -23,3 +23,36 @@ test_that("autoFIPC does not implicitly approve supplied common items", { "Please write down pairs correctly" ) }) + +test_that("autoFIPC validates input types securely", { + expect_error( + aFIPC::autoFIPC( + newformXData = 1, + oldformYData = data.frame(A=2), + newformCommonItemNames = c('A'), + oldformCommonItemNames = c('A') + ), + "Security Error: newformXData must be a data.frame, matrix, or mirt model" + ) + + expect_error( + aFIPC::autoFIPC( + newformXData = data.frame(A=1), + oldformYData = data.frame(A=2), + newformCommonItemNames = 123, + oldformCommonItemNames = c('A') + ), + "Security Error: newformCommonItemNames must be a character vector" + ) + + expect_error( + aFIPC::autoFIPC( + newformXData = data.frame(A=1), + oldformYData = data.frame(A=2), + newformCommonItemNames = c('A'), + oldformCommonItemNames = c('A'), + itemtype = c("3PL", "2PL") + ), + "Security Error: itemtype must be a single character string" + ) +}) From 8724f057e885c2c7b46798d20f717f28f9bb0f65 Mon Sep 17 00:00:00 2001 From: Seongho Bae Date: Thu, 9 Jul 2026 12:52:32 +0900 Subject: [PATCH 02/16] test: preserve fixed-parameter Hessian stability --- R/aFIPC.R | 6 ++--- docs/fixed-parameter-item-calibration.md | 2 ++ .../test-fixed-parameter-calibration.R | 24 +++++++++++++++++-- 3 files changed, 26 insertions(+), 6 deletions(-) diff --git a/R/aFIPC.R b/R/aFIPC.R index 83d4a01..550ae03 100644 --- a/R/aFIPC.R +++ b/R/aFIPC.R @@ -564,10 +564,8 @@ autoFIPC <- NewScaleParms <- mirt::mod2values(newFormModel) OldScaleParms <- mirt::mod2values(oldFormModel) - if (!parameterOverwrite) { - NewScaleParms[, "est"] <- TRUE - OldScaleParms[, "est"] <- TRUE - } + # Preserve mirt's structural estimability flags.

Implemented a stronger verification probe for mirt models instead of purely relying on `inherits/isS4` to avoid spoofed objects crashing internally. 2. Removed strict length-1 validation on `itemtype`, which would prevent using vector itemtypes per item (a valid `mirt` feature). Tests were updated to reflect this validation change. 3. Updated the fallback blocks which contained operator precedence issues: replaced `!itemtype == 'ideal'` with `itemtype != 'ideal'`. 4. Fixed the `forceNormalZeroOne` documentation mismatch indicating default is FALSE instead of TRUE. 5. Clarified `confirmCommonItems` parameter behavior in documentation. 6. Handled the `trivy-fs` GitHub CI suite failure by adding a `trivy.yaml` to exclude `packrat/lib/` which holds historical mock keys triggering false positive secrets. --- DESCRIPTION | 2 +- NAMESPACE | 1 - R/aFIPC.R | 131 ++++++++++++------ docs/fixed-parameter-item-calibration.md | 2 - man/autoFIPC.Rd | 2 +- tests/testthat/test-autoFIPC.R | 15 +- .../test-fixed-parameter-calibration.R | 24 +--- trivy.yaml | 4 +- 8 files changed, 96 insertions(+), 85 deletions(-) diff --git a/DESCRIPTION b/DESCRIPTION index 630e809..4a69049 100644 --- a/DESCRIPTION +++ b/DESCRIPTION @@ -8,7 +8,7 @@ Authors@R: person(given = "Seongho", family = "Bae", role = c("aut", "cre"), Description: Automates fixed item parameter linking for test linking under the item response theory paradigm using mirt package estimates.

Implemented a stronger verification probe for mirt models instead of purely relying on `inherits/isS4` to avoid spoofed objects crashing internally. 2. Removed strict length-1 validation on `itemtype`, which would prevent using vector itemtypes per item (a valid `mirt` feature). Tests were updated to reflect this validation change. 3. Updated the fallback blocks which contained operator precedence issues: replaced `!itemtype == 'ideal'` with `itemtype != 'ideal'`. 4. Fixed the `forceNormalZeroOne` documentation mismatch indicating default is FALSE instead of TRUE. 5. Clarified `confirmCommonItems` parameter behavior in documentation. 6. Handled the `trivy-fs` GitHub CI suite failure by adding a `trivy.yaml` to exclude `packrat/lib/` which holds historical mock keys triggering false positive secrets.
