Omnispace Agora Project before 26.10.0 contains a predictable password-reset token vulnerability that allows unauthenticated attackers to take over user accounts by computing the reset token as sha1(login.password), a deterministic and reusable value. Attackers can derive or brute-force the reset token from known or guessed login and password combinations to forge valid password-reset requests and hijack arbitrary accounts.
