Technical details
The vulnerability exists in Liman Render Engine's key exchange implementation, which fails to authenticate one or both communicating entities before establishing an encrypted channel. This permits an adversary-in-the-middle (AiTM) attack over a network to intercept, read, and potentially modify encrypted data. The flaw affects versions 1.0 through 1.2-74, with a fix available in version 1.2-75 and later.
