Description
An SQL injection vulnerability in Friendica through the 2026.08-dev branch allows unauthenticated remote attackers to execute arbitrary SQL statements via the photo-view order parameter. The parameter is concatenated unescaped into a SHOW COLUMNS query via a bare PDO::query() call, enabling stacked statement injection. An unauthenticated attacker can read, modify, or delete the entire database.

KEV Icon
CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is an SQL injection vulnerability in Friendica through the 2026.08-dev branch. It allows unauthenticated remote attackers to execute arbitrary SQL statements via the photo-view order parameter. The parameter is inserted directly into a SHOW COLUMNS query without proper escaping, enabling stacked statement injection.

Detection Guidance

To detect this SQL injection vulnerability in Friendica, inspect network traffic for requests to the photo-view endpoint with unusual order parameters. Check server logs for SHOW COLUMNS queries containing unescaped user input. Use tools like SQLMap to test for injection points in the order parameter.

Impact Analysis

An attacker could read, modify, or delete the entire Friendica database. This includes sensitive user data, credentials, and system configurations. Since no authentication is required, any internet-facing instance is at risk of full compromise.

Compliance Impact

This vulnerability likely violates GDPR due to unauthorized data access and potential data breaches. HIPAA compliance could also be affected if the Friendica instance stores protected health information. Organizations must address this to avoid regulatory penalties and legal consequences.

Mitigation Strategies

Immediately update Friendica to the latest patched version. If an update is unavailable, disable the photo-view functionality or restrict access to trusted users. Apply input validation to sanitize the order parameter before database queries. Monitor database logs for suspicious activity.
