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]
