Quick assessment

Affected
woodpecker-ci woodpecker
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

woodpecker-ci Woodpecker是woodpecker-ci团队开源的一个简单而强大的 CI/CD 引擎。 Woodpecker 3.15.0之前版本存在异常处理不当漏洞，该漏洞源于/api/orgs/lookup/*org_full_name端点注册了无身份验证中间件，且LookupOrg处理程序无条件取消引用会话用户，可能导致未经身份验证的攻击者通过触发空指针取消引用导致拒绝服务。

Vulnerability Title
Woodpecker < 3.15.0 - Unauthenticated NULL Pointer Dereference in /api/orgs/lookup Enables Log-Flooding Denial of Service
Source: CVE Program / CVE List V5
Vulnerability Description
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.
