Full Changelog: thephpleague/commonmark@2.10.0...2.10.1

2.10.0

This is a security release to address a denial of service vulnerability in the AttributesExtension.

Added

• Added a new table_of_contents/max_placeholder_entries option to limit how many table of contents entries a document may render across all of its placeholders (#1134)
• Added Cursor::matchInPlace(), which matches a regular expression at the cursor's position within the line using PCRE's native offset semantics instead of copying the remainder (#1145)
  • \G anchors at the cursor, ^ anchors at the start of the line, and lookbehinds and \b see the characters actually preceding the cursor; this keeps scanning loops linear and enables left-context assertions that match() cannot express
• Added RegexHelper::PARTIAL_LINK_TITLE_UNANCHORED and RegexHelper::PARTIAL_LINK_DESTINATION_BRACES, unanchored fragments so each call site can supply its own anchor
• Added a default_attributes configuration format which pairs the node attribute map with a new strict_callables option: ['default_attributes' => ['attributes' => [...], 'strict_callables' => true]]. With strict_callables enabled, only closures and invokable objects are treated as callbacks, so strings and arrays are always used as literal attribute values. Callbacks written as string or array callables can be wrapped with Closure::fromCallable(). The original format - passing the node map directly - is still accepted, and defaults strict_callables to false.
• Added a new slug_normalizer/reserved option which treats the given slugs as already-used, so colliding headings receive an incremental numeric suffix just like duplicate headings do (#1080)

Changed

• Changed the TableOfContents extension to render the table of contents once and share it across all placeholders instead of cloning it into each one (#1134)
  • A custom renderer registered for the TableOfContents node is no longer called once per placeholder, so it must return the same markup each time it is called for a given document (#1134)
  • The first placeholder receives the table of contents itself, so a document still contains a TableOfContents node for listeners which locate and reposition it (#1143)
• $environment->getConfiguration()->get('default_attributes') now returns the normalized structure with attributes and strict_callables keys instead of the node map; read default_attributes/attributes to get the map. Configuration written in either format continues to work unchanged.

Deprecated

• Deprecated RegexHelper::PARTIAL_LINK_TITLE and RegexHelper::REGEX_LINK_DESTINATION_BRACES; use the unanchored variants with an explicit anchor instead
• Deprecated the default_attributes strict_callables option, which will be removed in 3.0 when only closures and invokable objects will ever be treated as callbacks.

Fixed

• Fixed default_attributes values which happen to match the name of a PHP function - such as 'class' => 'link', 'header', 'key', 'range', or 'current' - being invoked as callbacks, producing errors like link() expects exactly 2 arguments, 1 given. Enable strict_callables to treat strings and arrays as literal attribute values (#1123)
• Fixed the DefaultAttributesExtension re-testing every configured value with is_callable() once per matching node, which asked the autoloader whether the first element of each array value named a real class every single time
• Fixed a default_attributes value which PHP treats as callable reporting its failure from inside whichever function it collided with; the error now names the attribute and node class responsible, and keeps the original error as its previous exception
• Fixed custom UniqueSlugNormalizerInterface implementations being wrapped by the built-in UniqueSlugNormalizer and never receiving the documented clearHistory() calls, which caused slug history to leak across documents when slug_normalizer/unique was set to 'document' (#1080)
  • Custom implementations are now trusted to enforce uniqueness themselves, per the interface contract; the extra deduplication layer the wrapper used to provide is no longer applied on top of them
• Fixed the AttributesExtension re-merging and re-filtering everything a node had already collected each time another attribute node was applied to it, causing long runs of distinctly-named attributes to be resolved in quadratic time, which could be abused to cause a denial of service - this completes the fix for GHSA-jjv6-8j6v-6j52, which covered only the class attribute (GHSA-8rr7-cvq3-gmfh)
• Fixed the AttributesExtension re-merging everything an attribute block had already collected on each of its continuation lines, causing long runs of distinctly-named attributes on consecutive lines to be resolved in quadratic time, which could be abused to cause a denial of service (GHSA-8rr7-cvq3-gmfh)

2.9.2

This release fixes a regression introduced in 2.9.0 which changed the behavior of Cursor::match() for certain regular expression patterns.

Changed

• Improved performance of reading single characters from multibyte lines
• Improved performance of locating the next non-space character on lines without tabs
• Optimized Cursor::advanceToNextNonSpaceOrNewline() to scan the line in place instead of copying everything left in the block on every call
• Optimized inline link destination parsing to scan the line in place, so its cost follows the length of the destination rather than the length of everything left in the block

Fixed

• Fixed a regression introduced in 2.9.0 where Cursor::match() treated text before the cursor as part of the match subject (#1145). Patterns were matched against the whole line at an offset, which silently changed the meaning of \b, \B, \A, lookbehinds, a ^ anywhere other than the very start of the pattern, and a leading ^ combined with the m modifier. match() once again matches against the remainder, exactly as it did in 2.8; the core parsers keep the optimized in-place matching via a new internal method with PCRE's native offset semantics, anchoring their patterns at the cursor with \G

• Fixed heading permalinks rendered with aria-hidden="true" remaining in the keyboard tab order; they are now also given tabindex="-1", as a focusable element removed from the accessibility tree has no accessible name to announce when focused (WCAG 4.1.2)
• Fixed cloning a node breaking the link from the original node's children back to their parent, silently corrupting the document that node belonged to; detaching or inserting around those children afterwards could drop nodes from the tree

Review was skipped due to path filters

⛔ Files ignored due to path filters (1)

• composer.lock is excluded by !**/*.lock

CodeRabbit blocks several paths by default. You can override this behavior by explicitly including those paths in the path filters. For example, including **/dist/** will override the default block on the dist directory, by removing the pattern from both the lists.
