chore(deps): bump lxml from 6.0.0 to 6.1.0

[dependabot]

Bumps lxml from 6.0.0 to 6.1.0.

Changelog

Sourced from lxml's changelog.

6.1.0 (2026-04-17)

This release fixes a possible external entity injection (XXE) vulnerability in iterparse() and the ETCompatXMLParser.

Features added

• GH#486: The HTML ARIA accessibility attributes were added to the set of safe attributes in lxml.html.defs. This allows lxml_html_clean to pass them through. Patch by oomsveta.

• The default chunk size for reading from file-likes in iterparse() is now configurable with a new chunk_size argument.

Bugs fixed

• LP#2146291: The resolve_entities option was still set to True for iterparse and ETCompatXMLParser, allowing for external entity injection (XXE) when using these parsers without setting this option explicitly. The default was now changed to 'internal' only (as for the normal XML and HTML parsers since lxml 5.0). Issue found by Sihao Qiu as CVE-2026-41066.

6.0.4 (2026-04-12)

Bugs fixed

• LP#2148019: Spurious MemoryError during namespace cleanup.

6.0.3 (2026-04-09)

Bugs fixed

• Several out of memory error cases now raise MemoryError that were not handled before.

• Slicing with large step values (outside of +/- sys.maxsize) could trigger undefined C behaviour.

• LP#2125399: Some failing tests were fixed or disabled in PyPy.

• LP#2138421: Memory leak in error cases when setting the public_id or system_url of a document.
