Optimizely CMS: Weak Password Requirements
CVE-2025-22390 is a high-severity weak password requirements vulnerability in Optimizely CMS from Optimizely, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version 12.32.0 as the first without the flaw, so updating Optimizely CMS to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.36% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Optimizely CMS to 12.32.0 or a later version.
- Read the advisory on support.optimizely.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
An issue was discovered in Optimizely EPiServer.CMS.Core before 12.32.0. A medium-severity vulnerability exists in the CMS due to insufficient enforcement of password complexity requirements. The application permits users to set passwords with a minimum length of 6 characters, lacking adequate complexity to resist modern attack techniques such as password spraying or offline password cracking.

The underlying weakness: Weak Password Requirements
The product does not require that users should have strong passwords.
How developers prevent this class of flaw
- Consider a second authentication factor beyond the password, which prevents the password from being a single point of failure. See CWE-308 for further information.
- Consider implementing a password complexity meter to inform users when a chosen password meets the required attributes.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: yes, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
