Bump sanitize-html from 2.17.1 to 2.17.5

[dependabot]

Bumps sanitize-html from 2.17.1 to 2.17.5.

Changelog

Sourced from sanitize-html's changelog.

2.17.5 (2026-06-10)

Security

• Added a number of new attributes to be protected against unsafe URLs, e.g. javascript: and similar. None of these are used in the default configuration of sanitize-html or apostrophe or likely to be used there, and some attributes, like an action for a form, are inherently unsafe to allow if XSS protection is your goal. Nevertheless it makes sense to block certain URL types where they are not appropriate. Some attributes are not supported at all by modern browsers but are included for completeness. Thanks to crattack for reporting the vulnerability.
• Address a potential vulnerability when nonTextTags is configured in a nonstandard way. While it is never a good idea to remove known non-text tags from the standard list e.g. script, styles, etc., this change ensures that doing so does not result in nested tags being passed through without sanitization when they are not expressly allowed. (ApostropheCMS would never trigger this situation.) Thanks to Dipanshu singh for pointing out the issue and contributing the fix.

2.17.4

Changes

• sanitize-html and launder now share a single implementation of naughtyHref, based on that which previously existed in sanitize-html.

Security

• Security vulnerability: the xmp tag could be used to pass forbidden markup through sanitize-html, even when xmp itself is not explicitly allowed All users of sanitize-html should update immediately. Thanks to Vincenzo Turturro for reporting the vulnerability.

2.17.3 (2026-04-15)

Security

• Fix vulnerability introduced in version 2.17.2 that allowed XSS attacks if the developer chose to permit option tags. There was no vulnerability when not explicitly allowing option tags.

2.17.2 (2026-03-19)

Changes

• Upgrade htmlparser2 from 8.x to 10.1.0. This improves security by correctly decoding zero-padded numeric character references (e.g., &[#0000001](https://github.com/apostrophecms/apostrophe/tree/HEAD/packages/sanitize-html/issues/0000001)) that previously bypassed javascript: URL detection. Also fixes double-encoding of entities inside raw text elements like textarea and option.
