CVE-2026-58455: Execution After Redirect (EAR) in Notifiarr dockwatch
Dockwatch versions up to 0.6.567 contain a critical unauthenticated OS command injection vulnerability. This flaw arises from a missing exit() call after an authentication redirect in loader.php combined with unsanitized input passed to shell_exec() in ajax/compose.php. Attackers can exploit this by setting a session flag through the incomplete authentication check and then injecting arbitrary shell commands via the composePath POST parameter. The vulnerability enables full host compromise, especially since the standard deployment mounts the Docker socket, increasing the attack surface.
AI Analysis
Technical Summary
CVE-2026-58455 is an unauthenticated OS command injection vulnerability in Notifiarr's dockwatch up to version 0.6.567. The issue stems from a missing exit() after an authentication redirect in loader.php, allowing attackers to bypass authentication checks and seed a session flag. Subsequently, unsanitized input passed to shell_exec() in ajax/compose.php's composePull action enables remote attackers to execute arbitrary shell commands. The typical deployment mounts the Docker socket, facilitating full host compromise through this vulnerability.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary shell commands on the host without authentication, leading to full host compromise. The presence of the Docker socket mount in standard deployments increases the severity by enabling container and host-level control.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the dockwatch service to trusted networks and users only. Monitor for unusual activity related to composePull actions and consider disabling or restricting the composePath parameter if possible.
