Omnispace Agora Critical Flaw Lets Attackers Predict Passwords and Takeover Accounts Before Users Log In
A critical vulnerability in Omnispace Agora Project allows attackers to predict default passwords, enabling account takeover before legitimate users can log in.
Key points
- CVE-2026-63149 affects Omnispace Agora Project versions prior to 26.10.0.
- The flaw is rated Critical with a CVSS score of 9.1 by the NVD.
- Attackers can predict temporary passwords using server time data.
Omnispace Agora Project versions before 26.10.0 contain a critical security flaw that exposes account credentials to prediction. The National Vulnerability Database records this issue as CVE-2026-63149 with a CVSS score of 9.1. This vulnerability allows attackers to bypass authentication by computing default or temporary passwords. The source material does not confirm the availability of a patch or update for affected versions.
How it unfolded
- The NVD published the record for CVE-2026-63149, identifying the insecure randomness issue.
- Analysts determined that the Txt::defaultPassword() function relies on PHP's uniqid().
- It was revealed that uniqid() uses server time in microseconds, making outputs predictable.
- Attackers were found to approximate account creation times to compute valid passwords.
Who is affected
Any deployment running Omnispace Agora Project before version 26.10.0 is vulnerable. The flaw stems from CWE-330, which addresses insecure randomness. Because the password generation depends on server time, attackers who can observe or estimate when an account is created can derive the password. This allows them to take over the account before the legitimate user logs in for the first time.
Our take on the response
The reliance on time-based randomness for security-sensitive data like passwords is a known risk. Using PHP's uniqid() for generating credentials that grant access is insufficient against determined adversaries. That suggests developers should avoid using predictable system states for secret generation. Organizations must treat this as an urgent exposure because the attack window exists before the user even interacts with the system.
Who needs to act first
Managed service providers should immediately inventory all Omnispace Agora Project instances. Teams usually prioritize systems exposed to the internet or those handling sensitive user data. Check whether current deployments are running versions older than 26.10.0. If a fix is not yet available, reduce exposure by restricting network access to these services. Back up configurations before making any changes. Test updates in isolated environments first to ensure stability. Monitor logs for unusual login attempts during this period.
What to do and how to stay safe: Omnispace
- Audit all servers to identify instances of Omnispace Agora Project running versions before 26.10.0.
- Restrict external access to affected systems using firewalls or network segmentation until a fix is applied.
- Monitor authentication logs for successful logins on temporary or default accounts shortly after creation.
- Once the vendor provides an update, test it in a non-production environment before rolling it out broadly.
