- Issue
- TL;DR This vulnerability affects all Kirby sites that use the snippet() helper or $kirby-snippet() method with a dynamic snippet name (such as a snippet name that depends on request or user data). Sites that only use fixed calls to the snippet() helper/$kirby-snippet() method (i.e. calls with a simple string for the snippet name) are not affected. ---- Introduction Kirby's snippet() helper and $kirby-snippet() method (in the following abbreviated to the snippet() helper) allow to load PHP snippet files that are normally stored in the site/snippets folder or registered by plugins through the snippets plugin extension. If the snippet() helper is called with an arbitrary snippet name, Kirby first checks if a file with this name exists in the snippets root (which defaults to site/snippets). This logic was vulnerable against path traversal attacks. By using special elements such as .. and / separators, attackers can escape outside of the restricted location to access files or directories…
Recommended action: Upgrade to 4.7.1, 3.10.1.2 or 3.9.8.3 by release line, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
