UNDERGOING ENRICHMENT

The CVE is currently being enriched by the Volerion team. The enrichment process results in the association of reference link tags, CVSS, and CPE applicability statement data.

Description

Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.9.6, Admin-configured OIDC token_url and user_info_url in includes/oidc/handle_oidc_callback.php:18-49 are used directly in curl_init() with zero SSRF filtering. Unlike logo/webhook URLs which have validate_webhook_url_for_ssrf(), OIDC URLs bypass all protections. Admin sets URL to http://169.254.169.254/latest/meta-data/ for cloud metadata access or internal network pivoting. This issue has been patched in version 4.9.6.
