DescriptionCVE.org

A security vulnerability has been detected in SeaCMS up to 13.6. This impacts the function parseIf of the file seacms_locoy_news.php of the component Locoy Collector. The manipulation of the argument pwd leads to code injection. The attack may be initiated remotely. The exploit has been disclosed publicly and may be used.

AnalysisAI

Code injection in SeaCMS's Locoy Collector module (versions up to 13.6) allows remote unauthenticated attackers to execute arbitrary PHP code by manipulating the pwd argument to the parseIf function in seacms_locoy_news.php. A publicly available proof-of-concept exploit exists, documented in a GitHub security advisory, elevating practical risk above the conservative 6.9 base score. …

Vulnerability AssessmentAI

Exploitation The Locoy Collector module (`seacms_locoy_news.php`) must be reachable over the network - if this is a default-installed component in SeaCMS, no special configuration beyond a standard installation is required. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 attack vector attributes (AV:N/AC:L/AT:N/PR:N/UI:N) characterize this as network-exploitable, unauthenticated, and requiring no special conditions - making it trivially automatable. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation No vendor-released patch version is identified in the available data - neither the VulDB report nor the GitHub advisory references an official upstream fix or patched release. … Detailed patch versions, workarounds, and compensating controls in full report.
