SCA: security update for idno/known (GHSA-fcrh-fqxh-6fx6)

critical Tenable Self-Hosted Container Security Plugin ID 438071

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Idno is a social publishing platform. Prior to version 1.6.4, a logic error in the API authentication flow
 causes the CSRF protection on the URL unfurl service endpoint to be trivially bypassed by any
 unauthenticated remote attacker. Combined with the absence of a login requirement on the endpoint itself,
 this allows an attacker to force the server to make arbitrary outbound HTTP requests to any host,
 including internal network addresses and cloud instance metadata services, and retrieve the response
 content. This issue has been patched in version 1.6.4. (CVE-2026-28508)
