Summary#

Validate real runtime boundaries, not just surface-form assumptions

Problem#

Security and correctness bugs often appear when code trusts lexical paths, nominal shapes, or unvalidated serialized input. Chained symlinks, malformed binary payloads, and shader/index math can all look valid until resolved or executed.

Solution#

Check resolved paths and runtime invariants at the point of use: validate actual prefixes after symlink resolution, reject corrupted or non-finite serialized values, and add explicit bounds checks around generated indexing logic.

Failure Modes#

  • Sanitizing only string form while resolved targets still escape the intended root
  • Assuming upstream data is well-formed and skipping defensive validation
  • Adding checks only for the direct case while missing chained or nested variants
