Vulnerability Description
Forgejo 13.0.0 through 16.0.4, when "[federation] ENABLED = true" is set, has a spoofing issue that affects identity integrity but does not allow account takeover or content modification. It does not verify that the HTTP Signature on an incoming ActivityPub activity was produced by the key belonging to the actor named in the activity body. The signature verification in routers/api/v1/activitypub/reqsignature.go validates the request signature, but the inbox activity handlers subsequently read the acting identity from the attacker-controlled JSON body without binding it to the verified signing key. Additionally, the signed Digest header is not recomputed against the received request body. A remote attacker who hosts a single valid ActivityPub actor and keypair can therefore submit signature-valid activities attributed to any actor identity they name.

Forgejo 信任管理问题漏洞
Vulnerability Description
Forgejo是Forgejo组织开源的一款源代码管理平台。 Forgejo 13.0.0版本至16.0.4版本存在信任管理问题漏洞,该漏洞源于未验证传入ActivityPub活动的HTTP签名是否由活动正文中指定行为者的密钥生成,且未对签名的Digest标头与接收请求正文重新计算,可能导致远程攻击者提交归因于任意行为者身份的签名有效活动,造成身份完整性受损。
