code-projects E-Commerce Website CVE-2025-12335

No vendor-released patch is identified at time of analysis. The primary mitigation is to upgrade from version 1.0 if a patched version becomes available from the code-projects maintainer (check https://code-projects.org/). Until a patch exists, implement immediate input validation and output encoding: ensure all user input to supp_name and supp_address parameters is validated against a whitelist of allowed characters (alphanumeric, spaces, hyphens) and reject or sanitize special characters such as < > " ' &. Apply context-aware HTML entity encoding (e.g., htmlspecialchars() in PHP with ENT_QUOTES flag) to all output rendered in /pages/supplier_update.php. Alternatively, disable the supplier update functionality entirely if not business-critical, or restrict access to this endpoint by IP whitelist or require strong authentication (multi-factor if possible) to reduce user interaction risk. Implement Content Security Policy (CSP) headers to mitigate the impact of injected scripts. Monitor web server logs for requests containing JavaScript patterns (script, onerror, onload, etc.) in these parameters to detect exploitation attempts.
