CVE-2026-1336 Overview
The AI ChatBot with ChatGPT and Content Generator by AYS plugin for WordPress contains a critical authorization vulnerability that allows unauthenticated attackers to access, modify, or delete sensitive API credentials. The vulnerability stems from missing capability checks on the store_data() and get_chatgpt_api_key() functions, enabling unauthorized manipulation of the plugin's ChatGPT API key configuration.
Critical Impact
Unauthenticated attackers can view, modify, or delete ChatGPT API keys, potentially leading to service disruption, unauthorized API usage, or financial impact through compromised credentials.
Affected Products
- AI ChatBot with ChatGPT and Content Generator by AYS plugin versions up to and including 2.7.5
- WordPress installations running affected plugin versions

Technical Details for CVE-2026-1336
Vulnerability Analysis
This vulnerability is classified as CWE-862 (Missing Authorization), a broken access control flaw that occurs when an application fails to verify whether a user has the necessary permissions to perform a sensitive action. In this case, the plugin exposes administrative functions without implementing proper WordPress capability checks, allowing any unauthenticated visitor to invoke these functions.
The attack is network-accessible and requires no user interaction or authentication, making it particularly dangerous for publicly accessible WordPress installations. An attacker can remotely access the vulnerable endpoints to steal the ChatGPT API key, which could then be used to generate unauthorized API requests or be sold on underground markets. Additionally, attackers can modify or delete the API key, disrupting the site's chatbot functionality.
Root Cause
The root cause is the absence of WordPress capability checks (such as current_user_can()) in the store_data() and get_chatgpt_api_key() functions. These functions handle sensitive API key operations but fail to verify that the requesting user has appropriate administrative privileges before executing. This violates the principle of least privilege and exposes critical functionality to unauthorized users.
The vulnerable code can be found in class-chatgpt-assistant-admin.php and class-chatgpt-assistant-db-actions.php within the plugin's codebase.
Attack Vector
The vulnerability is exploitable over the network without authentication. An attacker can send crafted HTTP requests to the WordPress installation targeting the vulnerable plugin endpoints. The get_chatgpt_api_key() function can be called to exfiltrate the stored API key, while store_data() can be leveraged to overwrite or delete the key configuration.
The vulnerability is exploited through direct HTTP requests to the plugin's AJAX handlers or REST endpoints. Since no capability checks are enforced, the plugin processes these requests regardless of the caller's authentication status. Attackers can craft requests that invoke the vulnerable functions, extracting or manipulating the ChatGPT API key stored in the WordPress database. For technical details, refer to the WordPress Plugin File - Admin and WordPress Plugin File - DB Actions references.
Detection Methods for CVE-2026-1336
Indicators of Compromise
- Unexpected changes to ChatGPT API key configuration in the plugin settings
- Unusual API usage or billing anomalies from OpenAI indicating unauthorized ChatGPT API consumption
- HTTP requests to plugin AJAX endpoints from unauthenticated sources or suspicious IP addresses
- WordPress error logs showing unauthorized access attempts to chatgpt-assistant endpoints
Detection Strategies
- Monitor WordPress access logs for requests to wp-admin/admin-ajax.php with actions related to the AYS ChatGPT plugin from non-authenticated users
- Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the vulnerable endpoints
- Review server logs for patterns of enumeration or exploitation attempts against WordPress plugin endpoints
- Deploy endpoint detection solutions capable of identifying unauthorized plugin configuration changes
Monitoring Recommendations
- Enable detailed logging for WordPress AJAX requests and plugin activity
- Configure alerts for any modification to the ChatGPT API key settings outside of authenticated admin sessions
- Monitor OpenAI API usage dashboards for unexpected activity indicating potential key theft
- Implement file integrity monitoring on plugin configuration files
How to Mitigate CVE-2026-1336
Immediate Actions Required
- Update the AI ChatBot with ChatGPT and Content Generator by AYS plugin to version 2.7.6 or later immediately
- Rotate any ChatGPT API keys that may have been exposed on vulnerable installations
- Review OpenAI API usage logs for signs of unauthorized access or unusual consumption patterns
- Audit WordPress access logs for any indicators of exploitation prior to patching
Patch Information
The vulnerability was partially addressed in version 2.7.5 and fully remediated in version 2.7.6. Site administrators should update to version 2.7.6 or later through the WordPress plugin update mechanism. After updating, it is strongly recommended to regenerate the ChatGPT API key as a precautionary measure, as the previous key may have been compromised.
For detailed vulnerability information, see the Wordfence Vulnerability Report.
Workarounds
- If immediate patching is not possible, temporarily disable the AI ChatBot with ChatGPT and Content Generator plugin until the update can be applied
- Implement WAF rules to block unauthenticated requests to the vulnerable plugin endpoints
- Remove or rotate the ChatGPT API key from the plugin configuration until the patch is deployed
- Restrict access to WordPress admin-ajax.php through server-level controls for non-authenticated users where feasible
# Temporary mitigation: Disable plugin via WP-CLI
wp plugin deactivate ays-chatgpt-assistant
# After updating, rotate API keys and verify plugin version
wp plugin update ays-chatgpt-assistant
wp plugin get ays-chatgpt-assistant --field=version
