Any user able to execute arbitrary queries \u2014 including unauthenticated guests when --allow-guests is enabled \u2014 can use built-in string functions to construct a large string and pass it to the JavaScript runtime for compilation, triggering a null pointer dereference in the underlying QuickJS-NG engine. This causes the server process to terminate immediately without graceful shutdown, requiring a manual restart. The issue was fixed by updating the rquickjs dependency from v0.9.0 to v0.11.0."

"value": "Woodpecker before 3.15.0 registers the /api/orgs/lookup/*org_full_name endpoint without authentication middleware, and the LookupOrg handler unconditionally dereferences the session user (user.ForgeID, via ForgeFromUser) when selecting the forge to query. For an unauthenticated request session.User returns nil, so any unauthenticated HTTP request triggers a NULL pointer dereference in the handler. The panic is recovered by gin recovery middleware and the server continues serving (returning HTTP 500), but each request writes a multi-line panic stack trace to the error log. A low-bandwidth unauthenticated attacker can repeatedly probe the endpoint to flood the logs (about 37 lines per request), inflating disk usage and downstream log-ingestion cost and burying legitimate log events."

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
