SCA: security update for samlify (GHSA-34r5-q4jw-r36m)

high Tenable Cloud Security Plugin ID 442259

Description

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

 - samlify is a Node.js library for SAML single sign-on. Prior to version 2.13.0, samlify’s template
 substitution only escapes attribute contexts. Values inserted into element text (e.g.,
 <saml:AttributeValue>) are not escaped. A normal user can inject XML markup into an attribute value (e.g.,
 email, name) and add new <saml:Attribute> elements inside the signed assertion. The IdP then signs the
 tampered assertion and the SP accepts the injected attributes as trusted. This allows privilege escalation
 when attributes are used for authorization (roles/groups). This issue has been patched in version 2.13.0.
 (CVE-2026-46490)

Solution

Update the samlify library and its related packages to version 2.13.0 or later.
