Bumps league/commonmark from 2.5.3 to 2.6.0.

Release notes

Sourced from league/commonmark's releases.

2.6.0

This is a security release to address potential denial of service attacks when parsing specially crafted, malicious input from untrusted sources (like user input). See GHSA-c2pc-g5qf-rfrf for more details.

Added

  • Added max_delimiters_per_line config option to prevent denial of service attacks when parsing malicious input
  • Added table/max_autocompleted_cells config option to prevent denial of service attacks when parsing large tables
  • The AttributesExtension now supports attributes without values (#985, #986)
  • The AutolinkExtension exposes two new configuration options to override the default behavior (#969, #987):
    • autolink/allowed_protocols - an array of protocols to allow autolinking for
    • autolink/default_protocol - the default protocol to use when none is specified
  • Added RegexHelper::isWhitespace() method to check if a given character is an ASCII whitespace character
  • Added CacheableDelimiterProcessorInterface to ensure linear complexity for dynamic delimiter processing
  • Added Bracket delimiter type to optimize bracket parsing

Changed

  • [ and ] are no longer added as Delimiter objects on the stack; a new Bracket type with its own stack is used instead
  • UrlAutolinkParser no longer parses URLs with more than 127 subdomains
  • Expanded reference links can no longer exceed 100kb, or the size of the input document (whichever is greater)
  • Delimiters should always provide a non-null value via DelimiterInterface::getIndex()
    • We'll attempt to infer the index based on surrounding delimiters where possible
  • The DelimiterStack now accepts integer positions for any $stackBottom argument
  • Several small performance optimizations
