CVE-2025-12898

Pretty Google Calendar <= 2.0.0 - Missing Authorization to Unauthenticated Google API Key Exposure

Published Dec 20, 2025 CVSS 3.1 · 5.3 Medium EPSS < 1% KEV · Not listed

Description

The Pretty Google Calendar plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the pgcal_ajax_handler() function in all versions up to, and including, 2.0.0. This makes it possible for unauthenticated attackers to retrieve the Google API key set in the plugin's settings.

Analysis

Technical impact

The Pretty Google Calendar WordPress plugin up to version 2.0.0 contains a missing capability check in the pgcal_ajax_handler function, allowing any user to trigger the AJAX endpoint and read the stored Google API key. This provides attackers with a credential that can be used to access the user’s Google Calendar data or impersonate the user in Google services. The weakness is classified as CWE‑862, reflecting an authorization error, and the CVSS score of 5.3 indicates moderate severity.

Affected Systems

All installations of the Pretty Google Calendar plugin v2.0.0 or earlier are affected. The plugin is distributed by lbell and is available through the WordPress plugin repository.

Risk and Exploitability

The exploit requires no special privileges; any unauthenticated visitor can invoke the vulnerable endpoint, so the attack vector is inferred as public. The low EPSS (<1%) suggests that this vulnerability is not commonly exploited in the wild. It is not listed in CISA’s KEV catalog. Therefore the risk is primarily the exposure of an API key, which can lead to privacy and potentially service disruption if the key is abused. The CVSS score indicates a moderate impact that should be remediated promptly.

Affected Products

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

Update Pretty Google Calendar to the latest release that includes a capability check for the AJAX handler.

Rotate or invalidate any Google API keys that may have been exposed as a precaution.
