0 CVE-2026-21907 is a medium severity vulnerability in Juniper Networks Junos Space affecting versions before 24.1R5. It involves the use of static key ciphers in the TLS/SSL server, which are considered broken or risky cryptographic algorithms. These static key ciphers reduce the confidentiality of data by allowing potential on-path attackers to decrypt traffic and do not support Perfect Forward Secrecy (PFS), compromising long-term confidentiality. The vulnerability does not affect integrity or availability and requires no authentication or user interaction but has a high attack complexity. No known exploits are currently reported in the wild. European organizations using Junos Space for network management should prioritize upgrading to versions 24.1R5 or later to mitigate this risk. Countries with significant Juniper Networks deployments, such as Germany, France, and the UK, are more likely to be impacted due to their extensive telecommunications and enterprise infrastructure. Mitigation involves disabling static key ciphers and enabling PFS-capable cipher suites, alongside applying vendor patches once available.
