2.6.0

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

Added

• Addedmax_delimiters_per_line config option to prevent denial of service attacks when parsing malicious input
• Addedtable/max_autocompleted_cells config option to prevent denial of service attacks when parsing large tables
• TheAttributesExtension now supports attributes without values (#985,#986)
• TheAutolinkExtension 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
• AddedRegexHelper::isWhitespace() method to check if a given character is an ASCII whitespace character
• AddedCacheableDelimiterProcessorInterface to ensure linear complexity for dynamic delimiter processing
• AddedBracket delimiter type to optimize bracket parsing

Changed

• [ and] are no longer added asDelimiter objects on the stack; a newBracket 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 viaDelimiterInterface::getIndex()
  • We'll attempt to infer the index based on surrounding delimiters where possible
• TheDelimiterStack now accepts integer positions for any$stackBottom argument
• Several small performance optimizations

2.5.3

Changed

• Made compatible with CommonMark spec 0.31.1, including:
  • Removesource, addsearch to list of recognized block tags

2.5.2

Changed

• Boolean attributes now require an explicittrue value (#1040)

Fixed

• Fixed regression where text could be misinterpreted as an attribute (#1040)
