The vulnerability arises due to unsafe usage of the logo_uri parameter in the Dynamic Client Registration request. An unauthenticated attacker can make a HTTP request from the vulnerable server to any address in the internal network and obtain its response (which might, for example, have a JavaScript payload for resultant XSS). The issue can be exploited to bypass network boundaries, obtain sensitive data, or attack other hosts in the internal network.","publishedAt":"2021-03-25T08:07:32.000Z","updatedAt":"2024-08-03T20:33:40.437Z","severity":null,"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://github.com/mitreid-connect/OpenID-Connect-Java-Spring-Server/releases","https://portswigger.net/research/hidden-oauth-attack-vectors"],"weaknesses":[],"ingestedAt":"2026-10-29T19:48:13.210Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2021/26xxx/CVE-2021-26715.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2021-26715","state":"PUBLISHED","datePublished":"2021-03-25T08:07:32.000Z","dateUpdated":"2024-08-03T20:33:40.437Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2021-02-05T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"The OpenID Connect server implementation for MITREid Connect through 1.3.3 contains a Server Side Request Forgery (SSRF) vulnerability.
