CVE-2017-0893 describes a Cross-Site Scripting (XSS) vulnerability in Nextcloud Server versions prior to 9.0.58, 10.0.5, and 11.0.3. This flaw originated from a vulnerable JavaScript library used for sanitizing user input, specifically due to a behavior change in Safari 10.1 and 10.2. Rated with a CVSS score of 5.4 (Medium), the vulnerability requires user interaction and low privileges, with a potential impact of limited confidentiality and integrity compromise. However, Nextcloud's strict Content-Security-Policy significantly mitigates exploitation on modern web browsers. There is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) or community discussion has been identified for this CVE. It is not listed on the KEV catalog or Hot List, indicating a low current threat level.
