Para is a multitenant backend server/framework for object persistence and retrieval. A vulnerability that exists in versions prior to 1.50.8 in `FacebookAuthFilter.java` results in a full request URL being logged during a failed request to a Facebook user profile. The log includes the user's access token in plain text. Since WARN-level logs are often retained in production and accessible to operators or log aggregation systems, this poses a risk of token exposure. Version 1.50.8 fixes the issue.

Affected: Maven: com.erudika:para-server

CWE ID: CWE-532 (Insertion of Sensitive Information into Log File) CVSS: 6.2 (Medium) Vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N

**Affected Component:** Facebook Authentication Logging **Version:** Para v1.50.6 **File Path:** para-1.50.6/para-server/src/main/java/com/erudika/para/server/security/filters/FacebookAuthFilter.java **Vulnerable Line(s):** Line 184 (logger.warn(...) with raw access token)

Technical Details:

The vulnerability is located in FacebookAuthFilter.java, where a failed request to Facebook’s user profile endpoint triggers the following log statement: ```java logger.warn("Facebook auth request failed: GET " + PROFILE_URL + accessToken, e);` ```

Here, `PROFILE_URL` is a constant: ```java private static final String PROFILE_URL = "https://graph.facebook.com/me?fields=name,email,picture.width(400).type(square).height(400)&access_token="; ``` This results in the full request URL being logged, including the user's access token in plain text. Since WARN-level logs are often retained in production and accessible to operators or log aggregation systems, this poses a risk of token exposure.
