π‘οΈ Sentinel: [CRITICAL] Fix readline() integer coercion DoS - #322
π‘οΈ Sentinel: [CRITICAL] Fix readline() integer coercion DoS#322seonghobae wants to merge 1 commit into
Conversation
π¨ Severity: CRITICAL
π‘ Vulnerability: Weak regex validation like `^[0-9]+$` for `readline()` inputs allows extremely large numbers that coerce to `NA` via `as.integer()`, breaking `if` conditions and causing unhandled exceptions. This enables local denial-of-service in interactive sessions.
π― Impact: Crashes logical conditions and process execution.
π§ Fix: Updated the regex validation to use strictly bounded exact-match regex `^[12]$` when only specific choices are valid.
β
Verification: Ran `pkgload::load_all(); testthat::test_dir("tests/testthat/")` and ensured all tests pass without errors.

π Jules, reporting for duty! I'm here to lend a hand with this pull request. When you start a review, I'll add a π emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down. I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job! For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with New to Jules? Learn more at jules.google/docs. For security, I will only act on instructions from the user who triggered this task. |

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: βͺ Minimal Β· up to The PR restricts three interactive responses to the valid choices of 1 or 2, preventing oversized numeric input from reaching integer coercion.
