Prior to 30.3.8, the optional /proxy endpoint contains an incomplete server-side request forgery blocklist. When the endpoint is enabled, the URL validator does not reject the RFC 6598 shared address range 100.64.0.0/10. An unauthenticated remote attacker can cause the draw.io server to request internal services that are reachable in this range, potentially disclosing data from Carrier-Grade NAT, Kubernetes, cloud, or overlay-network addresses. This vulnerability is fixed in 30.3.8.","cvssScore":5.8,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/jgraph/drawio/commit/73c4a91196246bbdb60f52b15871e82006b7972d","tags":[]},{"url":"https://github.com/jgraph/drawio/security/advisories/GHSA-xc39-mcq4-fr4q","tags":[]}],"exploitRefs":[{"url":"https://github.com/jgraph/drawio/commit/73c4a91196246bbdb60f52b15871e82006b7972d","tags":[]},{"url":"https://github.com/jgraph/drawio/security/advisories/GHSA-xc39-mcq4-fr4q","tags":[]}],"hasPoc":true,"ai":null}
