CVE-2025-11256

Kognetiks Chatbot <= 2.3.5 - Missing Authorization to Unauthenticated Limited File Uploads and Conversation Erasing

Published Oct 18, 2025 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed

Description

The Kognetiks Chatbot plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions in all versions up to, and including, 2.3.5. This makes it possible for unauthenticated attackers to upload limited safe files and erase conversations.

Analysis

Technical impact

The Kognetiks Chatbot WordPress plugin permits attackers without authentication to bypass authorization checks and upload a restricted set of files that the plugin deems safe. In addition, an unauthenticated attacker can invoke the delete function to erase all stored conversation data. This missing capability verification is a classic unauthorized access flaw, classified as CWE‑285, allowing data modification and loss of user interactions, which may compromise confidentiality or disrupt service continuity.

Affected Systems

WordPress installations that use the Kognetiks Chatbot plugin, versions 2.3.5 and earlier, are impacted by this vulnerability.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate severity, while an EPSS score of less than 1% suggests a very low likelihood of exploitation. The flaw is not currently listed in the CISA KEV catalog, meaning it has not been widely observed in the wild. Attackers can exploit the issue unauthenticated through web requests to the plugin’s upload or conversation‑erase endpoints, and doing so requires only internet access to the affected WordPress site.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Scan the site for any unexpected or unauthenticated uploaded files and remove them, and restore critical conversation data from backups if available.
