A SQL injection vulnerability in the activities API in OpenProject before 8.3.2 allows a remote attacker to execute arbitrary SQL commands via the id parameter. The attack can be performed unauthenticated if OpenProject is configured not to require authentication for API access.

→Monitor HTTP requests to /api/v3/activities/ where the `id` path parameter contains SQL metacharacters such as parentheses, encoded comparison operators (%3d), or time-delay payloads (PG_SLEEP) ↗
→Look for blind time-based SQLi patterns in requests to /api/v3/activities/ — specifically URL-encoded payloads containing PG_SLEEP, AND clauses, and numeric equality checks injected after the activity ID ↗
→Alert on unauthenticated requests (no session/API token) to /api/v3/activities/ endpoints, especially when the instance is configured to allow unauthenticated API access ↗

·The SQL injection is exploitable without authentication only when OpenProject is configured to allow unauthenticated API access; instances requiring authentication are harder to exploit remotely ↗
·All OpenProject versions from 5.0.0 through 8.3.1 are affected; versions older than 5.0.0 are not vulnerable ↗
