Summary
wg7.php in Webgalamb 7.0 makes opportunistic calls to htmlspecialchars() instead of using a templating engine with proper contextual encoding. Because it is possible to insert arbitrary strings into the database, any JavaScript could be executed by the administrator, leading to XSS.
Exploit prediction
1.06% chance of exploitation in the next 30 days, higher than 64% of all scored CVEs (FIRST EPSS, 2026-11-08).
