GHSA-4QPC-3HR4-R2P4 Symfony's YAML Parser Vulnerable to Exponential Memory Allocation via Recursive Collection-Alias Expansion ("Billion Laughs")

Description Symfony\Component\Yaml\Parser resolves YAML aliases anchor during parsing. Aliases that reference collections arrays, stdClass, TaggedValue-wrapped collections can themselves point to other collections containing aliases, creating exponential expansion at resolution time. A small inpu...

GHSA-C2P3-7M5P-CV8X Symfony hardened the parser when handling untrusted input

Description Symfony\Component\Yaml\Parser is the entry point for parsing YAML strings into PHP values via Yaml::parse. When the parser is exposed to attacker-controlled input, deeply nested mappings or sequences cause both the block-level Parser::parseBlock and inline Inline::parseSequence /...
