Project: Open Social [1] Date: 2024-September-04 Security risk: *Moderately critical* 10∕25 AC:Basic/A:None/CI:None/II:None/E:Theoretical/TD:All [2] Vulnerability: 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.

The distribution didn't validate the flood control limits on the password reset form correctly resulting in a potential attacker flooding the password reset which could result in a Denial of Service. Fortunately the message does not disclose any information to the attacker.

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]
