Attackers controlling a tool endpoint can return a 302 redirect to internal services, allowing the UTCP client to reach cloud metadata endpoints or internal HTTP services and return their response bodies to the caller.","cvssScore":8.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/universal-tool-calling-protocol/python-utcp/security/advisories/GHSA-9qhg-99ww-9mqc","tags":[]},{"url":"https://www.vulncheck.com/advisories/python-utcp-before-1.1.4-ssrf-via-unvalidated-http-redirects","tags":[]},{"url":"https://github.com/universal-tool-calling-protocol/python-utcp/security/advisories/GHSA-9qhg-99ww-9mqc","tags":[]}],"exploitRefs":[{"url":"https://github.com/universal-tool-calling-protocol/python-utcp/security/advisories/GHSA-9qhg-99ww-9mqc","tags":[]},{"url":"https://github.com/universal-tool-calling-protocol/python-utcp/security/advisories/GHSA-9qhg-99ww-9mqc","tags":[]}],"hasPoc":true,"ai":null}
