An attacker could potentially send a large number of emails if they know the email addresses of users in Kiwi TCMS. Additionally that may strain SMTP resources. \n\n### Patches\nUsers should upgrade to v12.0 or later.\n\n### Workarounds\nUsers may install and configure a rate-limiting proxy in front of Kiwi TCMS such as Nginx and/or configure rate limits on their email server when possible.\n\n### References\n[Disclosed by Ahmed Rabeaa Mosaa](https://huntr.dev/bounties/3b712cb6-3fa3-4f71-8562-7a7016c6262e)\n\n\n## Affected packages\n\n- `kiwitcms < 12.0`\n\n## Remediation\n\nUpgrade to a patched release:\n\n- `kiwitcms 12.0`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
