A vulnerability in Open VSX allows an unauthenticated attacker to poison the per-extension metadata cache by supplying a crafted X-Forwarded-Host header, replacing download, signature, and public-key URLs with attacker-controlled ones. The cache keys do not include the host, so poisoned entries are served to all clients for the entry's lifetime (1 hour by default, cluster-wide with Redis).

Original NVD description (English source)
Insecure permissions in fail2ban-client v0.11.2 allows attackers with limited sudo privileges to perform arbitrary operations as root. NOTE: this is disputed by multiple parties because the action for a triggered rule can legitimately be an arbitrary operation as root. Thus, the software is behaving in accordance with its intended privilege model.
