Release Notes

eemeli/yaml (yaml)

v2.9.1

• Limit recursive merge aliases (#​685, #​713)
• Simplify line unfolding during quoted string parsing (#​714)

v2.9.0

Compare Source

The changes here are really only patches, but I'm releasing this as a minor version to note a small change to the documentation of parseDocument() and parseAllDocuments(): I've removed the claim that they'll "never throw".

It remains the case that practically all non-malicious inputs will be handled without emitting an error, but there is a decent chance that code paths remain where e.g. a RangeError due to call stack exhaustion can be triggered by malicious inputs. Up to now, I've considered these as security vulnerabilities, and in fact it's the only category of error for which yaml CVEs have been issued so far.

Starting from this release, I'll be considering such errors as bugs, but not vulnerabilities. I do welcome people and/or LLMs looking for them, but please report them as normal issues rather than suspected security vulnerabilities. This also applies to previously undiscovered bugs in earlier releases.

• fix: Avoid calling Array.prototype.push.apply() with large source array
• fix(lexer): Avoid recursive calls that may exhaust the call stack

v2.8.4

Compare Source

• Disable alias resolution with maxAliasCount:0 (#​677)
• Handle invalid unicode escapes (e1a1a77)
• Apply minFractionDigits only to decimal strings (#​676)
