Project: Open Social [1]
Date: 2024-September-04
Security risk: *Moderately critical* 13∕25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default [2]
Vulnerability: Cross Site Scripting, Denial of Service

Affected versions: <12.3.8 || >=12.4.0 <12.4.5 || >=13.0.0 <13.0.0-alpha11
Description: 
Open Social is a Drupal distribution for online communities, which ships with
an optional module called Social Embed.

This module allows a website to display embedded content (such as photos or
videos) when a user posts a link to that resource, without having to parse
the resource directly.

Added URL's were not sufficiently validated which could lead to a DoS via
Blind SSRF and/or Application Takeover via Stored XSS.

This vulnerability is mitigated by the fact that social_embed submodule needs
to be enabled.

Solution: 
Install the latest version:

   * If you use Open Social 12.3.x, upgrade to Open Social 12.3.8 [3]
   * If you use Open Social 12.4.x, upgrade to Open Social 12.4.5 [4]
