This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify inventory and deployment contexts for potential exposure. Remediation priority is high due to the critical CVSS score of 9.1.

Why it matters

CVE-2026-63149 is a critical vulnerability in Omnispace Agora Project that allows attackers to predict default account passwords due to the use of PHP's uniqid() function. Defenders should prioritize remediation and assess exposure.

• Attackers can predict and compute default account passwords if they observe or approximate the account creation time.
• Account takeover is possible before the legitimate user logs in.
• Defenders should verify inventory and deployment contexts for potential exposure.
• Remediation priority is high due to the critical CVSS score of 9.1.

Technical summary

The Omnispace Agora Project before version 26.10.0 contains an insecure randomness vulnerability that allows attackers to predict temporary or default account passwords generated by Txt::defaultPassword() using PHP's uniqid() function based on server time in microseconds. Attackers who observe or approximate the account creation time can compute the predictable password and take over the account before the legitimate user logs in. The vulnerability has a critical CVSS score of 9.1, indicating a high severity level. Defenders should prioritize remediation and assess exposure.
