CVE-2025-12141: Grafana Alerting Editors can edit destination of webhooks they did not create

Noroxi assessment

Priority: Monitor (action score 5/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: grafana (openSUSE:Leap 16.0) 12.4.5-bp160.1.1; grafana (openSUSE:Tumbleweed) 12.4.4-1.1; grafana (SUSE:Linux Enterprise Module for Package Hub 15 SP7) 12.4.5-150200.3.91.1.

Low priority for now. Upgrade to grafana (openSUSE:Leap 16.0) 12.4.5-bp160.1.1; grafana (openSUSE:Tumbleweed) 12.4.4-1.1; grafana (SUSE:Linux Enterprise Module for Package Hub 15 SP7) 12.4.5-150200.3.91.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In Grafana's alerting system, users with edit permissions for a contact point, specifically the permissions “alert.notifications:write” or “alert.notifications.receivers:test” that are granted as part of the fixed role "Contact Point Writer", which is part of the basic role Editor - can edit contact points created by other users, modify the endpoint URL to a controlled server. By invoking the test functionality, attackers can capture and extract redacted secure settings, such as authentication credentials for third-party services (e.g., Slack tokens). This leads to unauthorized access and potential compromise of external integrations.
