Impact
Kuicms Php EE 2.0 contains a persistent cross‑site scripting flaw that occurs when user‑submitted content from the bbs reply endpoint is stored without proper escaping. An attacker can send a POST request to /web/?c=bbs&a=reply with JavaScript and HTML in the content parameter, and the payload is stored and rendered in browsers when the reply is viewed, allowing arbitrary script execution. This weakness is a classic input validation error (CWE‑79).
Affected Systems
The vulnerability targets the Kuicms Php EE 2.0 CMS. No other versions are reported as affected. Administrators should confirm whether their deployed instances run version 2.0 and whether the bbs reply feature is enabled.
Risk and Exploitability
The CVSS score of 5.1 indicates medium severity. EPSS data is not available and the flaw is not listed in the CISA KEV catalogue, suggesting no documented exploitation to date. Attackers can reach the vulnerable endpoint without authentication by sending a crafted POST request to /web/?c=bbs&a=reply, so the attack vector is unauthenticated network access to the application.
