Lifecycle Timeline

Vvveb before 1.0.8.2 contains an information disclosure vulnerability in the cron controller that allows unauthenticated attackers to retrieve the application's secret cron key. Attackers can access the cron controller without authentication and retrieve the exposed secret key from the response, enabling them to trigger scheduled task execution outside of the intended schedule.
AnalysisAI
Vvveb before 1.0.8.2 exposes the application's secret cron key through an unauthenticated cron controller endpoint, allowing remote attackers to retrieve this sensitive credential and trigger scheduled tasks outside their intended execution windows. The vulnerability affects all deployments with the vulnerable cron controller accessible over the network, with CVSS 5.3 reflecting confidentiality impact from information disclosure without authentication requirements.
Technical ContextAI
Vvveb is a PHP-based page builder and content management system. The vulnerability exists in the cron controller (app/controller/cron.php), which is responsible for managing scheduled task execution. The root cause is CWE-497 (Exposure of Sensitive System Information to an Unauthorized Control Sphere), where the cron controller inappropriately exposes the secret cron key in HTTP responses without authentication. The cron key is a shared secret meant to authorize legitimate scheduled task invocations; exposing it allows attackers to forge legitimate-appearing requests. The fix (commit 517bc09) removes the code that echoes the URL containing the key parameter, preventing disclosure.
RemediationAI
Upgrade Vvveb to version 1.0.8.2 or later, which includes the fix that removes the cron key exposure from controller output. The patch is available from the vendor repository (https://github.com/givanz/Vvveb/commit/517bc09faf44136e72de391aacc8b90a706f7ae7). For organizations unable to upgrade immediately, implement network-level access controls to restrict access to the cron controller endpoint (typically /cron or /app/controller/cron.php) to only trusted internal or scheduled-task-initiating systems; this prevents unauthenticated external attackers from reaching the endpoint while permitting legitimate cron execution. Additionally, rotate the cron key in the application configuration after patching if the key was previously exposed, as any attacker with network access prior to remediation may have retrieved it. Monitor application logs for unauthorized cron endpoint access from unexpected IP ranges.
