v1.14.2

andimarafioti/faster-qwen3-ttsv1.14.2Aug 13, 2026by abimaelmartell

AI Summary

This release hardens the parser against pathological PDFs by capping resource expansion limits to prevent crafted documents from causing unbounded CPU or memory usage. It also improves the extraction of nested form text and table structures.

Key Highlights

Caps expansion for Form XObjects, CID ranges, and content streams to prevent DoS
Form XObjects now track the text line matrix and honor spacing operators
Small-caps runs merge instead of being read as extra table columns

New Features

Form XObject text line matrix tracking
Small-caps run merging
Expansion caps for CID ranges and content streams
Detector lookback bounds for Tj/TJ operators

## 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)
