[Security] Bump path-to-regexp and express

Dependabot requested to merge dependabot-npm_and_yarn-multi-2ed376dc12 into master

Bumps path-to-regexp to 8.1.0 and updates ancestor dependency express. These dependencies need to be updated together.

Updates path-to-regexp from 0.1.7 to 8.1.0 This update includes a security fix.

Vulnerabilities fixed

path-to-regexp outputs backtracking regular expressions

Impact

In certain cases, path-to-regexp will output a regular expression that can be exploited to cause poor performance.

Patches

For users of 0.1, upgrade to 0.1.10. All other users should upgrade to 8.0.0.

Version 0.1.10 adds backtracking protection when a custom regular expression is not provided, so it's still possible to manually create a ReDoS vulnerability if you are providing custom regular expressions.

Version 8.0.0 removes all features that can cause a ReDoS and stops exposing the regular expression directly.

Workarounds

All versions can be patched by providing a custom regular expression for parameters after the first in a single segment. As long as the custom regular expression does not match the text before the parameter, you will be safe. For example, change /:a-:b to /:a-:b([^-/]+).

If paths cannot be rewritten and versions cannot be upgraded, another alternative is to limit the URL length. For example, halving the attack string improves performance by 4x faster.

Release notes

Sourced from path-to-regexp's releases.

v8.1.0

Added

  • Adds pathToRegexp method back for generating a regex
  • Adds stringify method for converting TokenData into a path string

Simpler API

Heads up! This is a fairly large change (again) and I need to apologize in advance. If I foresaw what this version would have ended up being I would not have released version 7. A longer blog post and explanation will be incoming this week, but the pivot has been due to work on Express.js v5 and this will the finalized syntax used in Express moving forward.

Added

  • Adds key names to wildcards using *name syntax, aligns with : behavior but using an asterisk instead

Changed

  • Removes group suffixes of ?, +, and * - only optional exists moving forward (use wildcards for +, {*foo} for *)
  • Parameter names follow JS identifier rules and allow unicode characters

Added

  • Parameter names can now be quoted, e.g. :"foo-bar"
  • Match accepts an array of values, so the signature is now string | TokenData | Array<string | TokenData>

Removed

  • Removes loose mode
  • Removes regular expression overrides of parameters

https://github.com/pillarjs/path-to-regexp/compare/v7.1.0...v8.0.0

Support array inputs (again)

Added

  • Support array inputs for match and pathToRegexp 3fdd88f

https://github.com/pillarjs/path-to-regexp/compare/v7.1.0...v7.2.0

Strict mode

Added

  • Adds a strict option to detect potential ReDOS issues

Fixed

  • Fixes separator to default to suffix + prefix when not specified
  • Allows separator to be undefined in TokenData
    • This is only relevant if you are building TokenData manually, previously parse filled it in automatically

Changelog

Sourced from path-to-regexp's changelog.

Moved to GitHub Releases

3.0.0 / 2019-01-13

  • Always use prefix character as delimiter token, allowing any character to be a delimiter (e.g. /:att1-:att2-:att3-:att4-:att5)
  • Remove partial support, prefer escaping the prefix delimiter explicitly (e.g. \\/(apple-)?icon-:res(\\d+).png)

2.4.0 / 2018-08-26

  • Support start option to disable anchoring from beginning of the string

2.3.0 / 2018-08-20

  • Use delimiter when processing repeated matching groups (e.g. foo/bar has no prefix, but has a delimiter)

2.2.1 / 2018-04-24

  • Allow empty string with end: false to match both relative and absolute paths

2.2.0 / 2018-03-06

  • Pass token as second argument to encode option (e.g. encode(value, token))

2.1.0 / 2017-10-20

  • Handle non-ending paths where the final character is a delimiter
    • E.g. /foo/ before required either /foo/ or /foo// to match in non-ending mode

2.0.0 / 2017-08-23

  • New option! Ability to set endsWith to match paths like /test?query=string up to the query string
  • New option! Set delimiters for specific characters to be treated as parameter prefixes (e.g. /:test)
  • Remove isarray dependency
  • Explicitly handle trailing delimiters instead of trimming them (e.g. /test/ is now treated as /test/ instead of /test when matching)
  • Remove overloaded keys argument that accepted options
  • Remove keys list attached to the RegExp output
  • Remove asterisk functionality (it's a real pain to properly encode)
  • Change tokensToFunction (e.g. compile) to accept an encode function for pretty encoding (e.g. pass your own implementation)

1.7.0 / 2016-11-08

  • Allow a delimiter option to be passed in with tokensToRegExp which will be used for "non-ending" token match situations

1.6.0 / 2016-10-03

  • Populate RegExp.keys when using the tokensToRegExp method (making it consistent with the main export)
  • Allow a delimiter option to be passed in with parse
  • Updated TypeScript definition with Keys and Options updated

1.5.3 / 2016-06-15
