Doc Text:	A flaw was found in graphite-web. The send_email in the graphite-web/webapp/graphite/composer/views.py function is vulnerable to a Server-side request forgery (SSRF). This flaw allows an attacker to use the vulnerable SSRF endpoint to have the Graphite web server request any resource. An attacker can exfiltrate any information due to the response the SSRF request encodes into an image file sent to an email address supplied by the attacker.	Story Points:	---

Description Marian Rehak 2021-09-07 10:38:46 UTC

send_email in graphite-web/webapp/graphite/composer/views.py is vulnerable to SSRF. The vulnerable SSRF endpoint can be used by an attacker to have the Graphite web server request any resource. The response to this SSRF request is encoded into an image file and then sent to an e-mail address that can be supplied by the attacker. Thus, an attacker can exfiltrate any information.
