Mistune inline_parser: quadratic-time parsing on long runs of `**x**` and `***x***` emphasis pairs

Summary Type: Algorithmic-complexity DoS in core emphasis parsing. A long sequence of well-formed x strong or x strong-emphasis combined pairs causes ON² parser work. Distinct from the bracket-bomb DoS repetition and from the formatting-plugin DoS /==/^^; this one fires on default-config mistune...

GHSA-FFQ3-XPV3-J92Q Mistune block_parser: quadratic-time parsing on long lists of repeated reference-link definitions

Summary Type: Algorithmic-complexity DoS in reference-link definition handling. A markdown document with N reference-link definitions of the same key or many distinct keys takes ON² parser time. 5000 repeated a: u\n definitions take 1.1 second; 10000 → 4.5 seconds.

Summary js-yaml v5.x introduces YAML11SCHEMA support with the !!omap ordered map tag. The omapTag.addItem function performs a linear On scan for duplicate key detection on every insertion, resulting in On^2 total time to parse a document with n omap entries. An attacker can send a small crafted...

brace-expansion: DoS via exponential-time expansion of consecutive non-expanding {} groups

Summary brace-expansion's expand exhibits exponential-time - O2ⁿ - behavior in the number of consecutive non-expanding groups. A short, all-ASCII input 90 bytes/30 groups blocks the calling thread for minutes; a slightly longer input hangs it effectively indefinitely. Because the dominant consume...
