CVE-2023-6877 is a Stored Cross-Site Scripting (XSS) vulnerability affecting the RSS Aggregator by Feedzy plugin for WordPress, versions up to and including 4.3.3. This flaw allows authenticated attackers with contributor-level access or higher to inject malicious web scripts into pages. The vulnerability stems from insufficient input sanitization and output escaping of the Content-Type field in error messages when an invalid RSS feed is retrieved. The vulnerability has a CVSS score of 5.4 (Medium), indicating a moderate severity. An attacker can exploit this remotely with low attack complexity, requiring user interaction (accessing an injected page) to trigger the XSS. Successful exploitation could lead to limited confidentiality and integrity impacts. Currently, there is no evidence of active exploitation, and no public exploit code (Metasploit, Nuclei, ExploitDB) is available. Community discussion and media coverage for this CVE are minimal, suggesting it has not garnered significant attention.
