String processing operations should always bound their inputs first if the input is untrusted and can be arbitrarily large. **Prevention:** Cap the length of client-provided filename strings early by slicing them (e.g. `filename = filename[-512:]`) before doing more complex string parsing or regex replacements, especially when only the basename suffix is relevant. - -## 2026-09-02 - Prevent Memory Exhaustion via Unbounded Form Fields -**Vulnerability:** Textual `Form` fields in FastAPI (`language`, `mode`) lacked `max_length` limits, which could allow memory exhaustion via large payloads since `python-multipart` loads form data into memory before routing. -**Learning:** Even though payload size limits might exist for uploaded files, missing constraints on simple form fields allow attackers to send massive strings in multipart payloads, causing memory bloat (DoS). -**Prevention:** Always set explicit `max_length` attributes on `Form()` fields in FastAPI endpoints. - -## 2026-09-03 - Upgrade pypdf to 6.16.2 to resolve CVEs -**Vulnerability:** pypdf versions below 6.16.2 contain security vulnerabilities flagged by trivy-fs (CVE-2026-84309, CVE-2026-84310, CVE-2026-84311). -**Learning:** When updating the `pypdf` dependency to address security vulnerabilities from `trivy-fs` CI failures, version assertions in `tests/test_project_metadata.py` and the specific constants (`_REQUIRED_PYPDF_VERSION`, `_LOCKED_PYPDF_REQUIREMENT`) in `tests/test_pypdf_security_floor.py` must be updated to match the new version to prevent test failures. -**Prevention:** Regularly scan dependencies with trivy and upgrade vulnerable packages, updating hardcoded test assertions accordingly.

This can allow command or log injection even when `shell=False` is used, by passing arguments containing newlines. +**Vulnerability:** The blocklist regex `_UNSAFE_CHARS_PATTERN` for CLI arguments did not explicitly filter newline (\n) or carriage return (\r) characters. This can allow command or log injection even when `shell=False` is used, by passing arguments containing newlines. **Learning:** Shell metacharacter blocklists must include whitespace metacharacters like newlines and carriage returns, as these can bypass checks and manipulate logs or downstream argument parsing. **Prevention:** Explicitly add \n and \r to the `_UNSAFE_CHARS_PATTERN` blocklist for CLI arguments.
