Description

The metascraper-logo-favicon plugin makes HTTP requests to URLs extracted from attacker-controlled HTML without going through the application’s validateUrl() SSRF protections. This allows any authenticated user to make the server fetch arbitrary internal URLs by bookmarking a page containing a crafted <link rel="icon"> tag.

Recommendation

Update the @karakeep/sdk package to the latest compatible version. Followings are version details:

  • Affected version(s): <= 0.31.0
  • Patched version(s): 0.32.0
