CVE-2025-53106

25
FAUCET Score

CVE-2025-53106 is a high-severity privilege escalation vulnerability affecting Graylog versions 6.2.0 through 6.2.3 and 6.3.0-alpha.1 through 6.3.0-rc.1. An authenticated attacker can exploit a weak permission check in the REST API to create API tokens for other users, including administrators, thereby gaining elevated privileges. This allows for full compromise of confidentiality, integrity, and availability. While no public exploits or active exploitation have been observed, the vulnerability has a CVSS score of 8.8 (High) and a FAUCET Risk Score of 83/100, indicating a significant risk. Patches are available in versions 6.2.4 and 6.3.0-rc.2, and a workaround involves disabling personal access token creation.
