ANALYZED

This CVE record has been analyzed and enriched by NVDAPI.com as an independent party.

Description

The YML for Yandex Market plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 5.10.0 via the 'y4ym_check_action' parameter. This makes it possible for unauthenticated attackers to extract the merchant's plaintext Yandex Market API key written to the publicly accessible log file at wp-content/uploads/y4ym/yml-for-yandex-market.log, granting full control over the merchant's marketplace catalogue, prices, and stock. Exploitation requires that the targeted feed has a stored Yandex Market API key and that the y4ym_keeplogs option is enabled — both conditions that represent normal, documented plugin usage actively encouraged by the plugin's own support and feedback workflow.
