Agora Project: Use of Insufficiently Random Values

Published Updated By the CyberSecBulletin desk

CVE-2026-63149 is a high-severity use of insufficiently random values vulnerability in Agora Project from Omnispace, with a CVSS 3.1 base score of 7.4 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 26.10.0 as the first without the flaw, so updating Agora Project to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.38% chance of exploitation within 30 days, which is low compared with other CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update Agora Project to 26.10.0 or a later version.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description

Omnispace Agora Project before 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 underlying weakness: Use of Insufficiently Random Values

The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.

How developers prevent this class of flaw

  • Use a well-vetted algorithm that is currently considered to be strong by experts in the field, and select well-tested implementations with adequate length seeds. In general, if a pseudo-random number generator is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts. Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a random enough number.
  • Consider a PRNG that re-seeds itself as needed from high quality pseudo-random output sources, such as hardware devices.
  • Use products or modules that conform to FIPS 140-2 to avoid obvious entropy problems. Consult FIPS 140-2 Annex C (Approved Random Number Generators).
