What is in scope
7 targets. 5 excluded.

Web
-
Credential and PKI handling in the pki tool and the credential plugins: X.509 chain building, CRL and OCSP processing, and the RSA and ECDSA verification paths
Products and areas
-
Reports go to the strongSwan security address, which also serves as the project's OSS-Fuzz contact, and the object is the upstream strongSwan tree rather than a vendor's appliance fork or another IPsec implementation
Products and areas
-
The authentication plugin family end to end, EAP-TLS, EAP-TTLS and EAP-MSCHAPv2 included, together with the identity-matching logic that turns an exchange into an authentication decision
Products and areas
-
The charon daemon in full: the IKEv1 and IKEv2 message parsers reachable pre-authentication on UDP/500 and UDP/4500, and the state machine behind them
Products and areas
-
The kernel interface plugins, kernel-netlink above all, and XFRM policy and SA installation, where a policy confusion becomes a traffic-selector bypass
Products and areas
-
The vici and swanctl control interface and the legacy stroke socket
Products and areas
No target matches. Try part of a host name, such as the company name.
Out of scope 5
Don't test these. A program can exclude a host another program covers; the program you report to decides.
-
Kernel XFRM and IPsec bugs, which belong to the Linux kernel scope row rather than to strongSwan
-
Libreswan and other IPsec implementations, which are separate projects with no OSS-Fuzz integration and no pathway
-
One-line fixes for non-exploitable crashes, which the Patch Rewards rules exclude
-
Vendor firmware forks shipped inside appliances rather than the upstream repository
-
Weak proposals or pre-shared keys the operator chose, which is configuration rather than a code defect
