CVE-2021-23927 describes a Server-Side Request Forgery (SSRF) vulnerability in OX App Suite versions through 7.10.4. This flaw allows an authenticated attacker to craft a PUT request to the appsuite/api/oauth/proxy endpoint, using a URL containing an "@" character to bypass security controls and make the server request arbitrary internal or external resources. Rated 6.4 MEDIUM, the vulnerability has a network attack vector and low attack complexity, potentially leading to limited confidentiality and integrity impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or inclusion in CISA's KEV catalog, though it has garnered minimal community discussion and media coverage.
