    fix: add depth limit to TableBorderProcessor to prevent stack overflow

    frostbyte_neo 发布于 2026-02-05 05:45:36 +00:00

    Add defensive depth limit (MAX_NESTED_TABLE_DEPTH=10) for nested table
    processing. Uses ThreadLocal to track recursion depth and prevents
    stack overflow from malicious or malformed PDFs with deeply nested tables.

    Real-world PDFs rarely have tables nested more than 2-3 levels, so
    depth limit of 10 provides ample margin for legitimate use cases.
