Bumps highlight.js from 9.18.1 to 9.18.5. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Prototype Pollution in highlight.js

Impact

Affected versions of this package are vulnerable to Prototype Pollution. A malicious HTML code block can be crafted that will result in prototype pollution of the base object's prototype during highlighting. If you allow users to insert custom HTML code blocks into your page/app via parsing Markdown code blocks (or similar) and do not filter the language names the user can provide you may be vulnerable.

The pollution should just be harmless data but this can cause problems for applications not expecting these properties to exist and can result in strange behavior or application crashes, i.e. a potential DOS vector.

If your website or application does not render user provided data it should be unaffected.

Patches

Versions 9.18.2 and 10.1.2 and newer include fixes for this vulnerability. If you are using version 7 or 8 you are encouraged to upgrade to a newer release.

Workarounds

Patch your library

Manually patch your library to create null objects for both languages and aliases:

const HLJS = function(hljs) {
</tr></table> ... (truncated)
Affected versions: < 9.18.2

Changelog

Sourced from highlight.js's changelog.

Release v9.18.5

Version 9 has reached end-of-support and will not receive future updates or fixes.

Please see VERSION_10_UPGRADE.md and perhaps SECURITY.md.

  • enh: Post-install script can be disabled with HLJS_HIDE_UPGRADE_WARNING=yes
  • fix: Deprecation notice logged at library startup a console.log vs console.warn.
    • Notice only shown if actually highlighting code, not just requiring the library.
    • Node.js treats warn the same as error and that was problematic.
    • You (or perhaps your indirect dependency) may disable the notice with the hideUpgradeWarningAcceptNoSupportOrSecurityUpdates option
    • You can also set HLJS_HIDE_UPGRADE_WARNING=yes in your envionment to disable the warning

Example:

hljs.configure({
  hideUpgradeWarningAcceptNoSupportOrSecurityUpdates: true
})

Reference: highlightjs/highlight.js#2877

Release v9.18.4

Version 9 has reached end-of-support and will not receive future updates or fixes.
