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.

π Info: Trailing-newline anchoring safe under default regex engine
$ in ^[^\x00-\x1F\x7F]+$ matches before a trailing newline under Python re, which would let "foo\n" pass. Pydantic v2 defaults to the Rust regex engine where $ is end-of-text, and no regex_engine override exists, so no bypass. Consistent with prior use in ProjectCreateIn and ConnectionCreateIn.

π¨ Severity: MEDIUM
π‘ Vulnerability: Several Pydantic string fields representing names (in
DiagramViewCreateIn,TableAnnotationUpsertIn, andApiKeyCreateInschemas) lacked strict validation against control characters.π― Impact: Permitting ASCII control characters (like
\n,\r,\t,\x00) in user input can lead to log injection (CRLF), null byte injection, or terminal escape sequence injection if these values are subsequently rendered or logged verbatim.π§ Fix: Added the
pattern=r"^[^\x00-\x1F\x7F]+$"regex constraint to these specific string fields to reject all ASCII control characters while permitting standard alphanumeric and unicode inputs.β Verification: Verified by running the backend test suite via
uv run pytest, which passes successfully, ensuring normal inputs are unaffected. Added a finding to.jules/sentinel.md.PR created automatically by Jules for task 2881124898739978992 started by @seonghobae
