anomalyco/opentuiv1.14.2Aug 13, 2026by abimaelmartell

AI Summary

Focuses on hardening parsing against pathological PDFs to prevent unbounded CPU or memory usage, with specific improvements to text extraction accuracy in complex layouts.

Key Highlights

Caps Form XObject expansion to prevent DoS attacks
Limits CID `/W` ranges and content-stream decode operations
Tracks text line matrix in Form XObjects for better spacing
Merges small-caps runs to prevent table column misreading

New Features

Resource bounds enforcement for Form XObjects and CID ranges
Content-stream decode bounds
Text line matrix tracking (T*, TL, etc.)
Small-caps run merging

## Highlights

- Caps Form XObject expansion, CID `/W` ranges, Encoding/ToUnicode CMaps, content-stream decode, detector `Tj`/`TJ` lookback, and disjoint-rect clustering so crafted PDFs cannot force unbounded CPU or memory (#370, #372, #373, #375, #379, #380, #381).
- Form XObjects now track the text line matrix and honor `T*` / `TL` / `'` / `"` / `Tc` / `Tw`, so nested form text keeps the right spacing (#369).
- Small-caps runs merge instead of being read as extra table columns (#371).

## Changes since 1.14.1

Source: [`f4aab3b...4bee4f9`](https://github.com/firecrawl/pdf-inspector/compare/f4aab3b...4bee4f9)

### Resource bounds
- Bound Form XObject expansion per page (#370)
- Bound CID `/W` range expansion (#372)
- Cap content-stream decode before allocating operators (#373)
- Bound Encoding CMap `cidrange` expansion (#375)
- Bound ToUnicode `bfrange` expansion during subset remap (#379)
- Bound detector `Tj`/`TJ` operand lookback to the previous operator (#380)
- Bound disjoint-rect table clustering so overlap tests stay subquadratic (#381)

### Extraction quality
- Track the text line matrix and handle `T*` / `TL` / `'` / `"` / `Tc` / `Tw` in Form XObjects (#369)
- Merge small-caps runs so they stop reading as table columns (#371)
