• Severity: medium (CVSS 6.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.3% probability of exploitation in the next 30 days
• Public exploit or detection template: yes
• Published: 2026-03-07 · updated 2026-06-17
• Weakness: CWE-79

Description

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, passwordreset.php outputs $_GET["token"] and $_GET["email"] directly into HTML input value attributes using <?= $token ?> and <?= $email ?> without calling htmlspecialchars(). This allows reflected XSS by breaking out of the attribute context. This issue has been patched in version 4.6.2.

Affected products

• ellite Wallos: before 4.6.2 — fixed in 4.6.2

How to fix

Upgrade to a fixed version: ellite Wallos 4.6.2. Check the vendor advisory for mitigations.
