GHSA-6C6R-5XR4-CR5M Gitea: Cross-repository issue/comment attachment re-linking can expose private attachment content

Summary Gitea's issue and comment attachment update paths accept attachment UUIDs without verifying that each attachment belongs to the target issue/comment repository. If an authenticated attacker knows a victim attachment UUID, they can re-link that attachment to an attacker-controlled issue or...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the oauth2UpdateAvatarIfNeed function. An attacker can cause the server to make arbitrary outbound HTTP GET requests by supplying a crafted avatar URL through the OAuth2/OIDC picture claim. This can...

GHSA-X77V-Q46J-393G Gitea: Blind SSRF in OAuth2 avatar synchronization via unvalidated OIDC picture claim

Summary When oauth2client UPDATEAVATAR = true is enabled, Gitea fetches the avatar URL received from an OAuth2/OIDC provider using Go's default HTTP client. The URL comes from the user's OAuth/OIDC avatar value, commonly the OIDC picture claim. The affected code path calls http.Geturl without...

GHSA-9MQ6-MQJJ-C2C5 Gitea: Unbounded Arch package file metadata can cause resource amplification in Gitea package uploads

Summary Hello Gitea Security Team, Thank you for your continued work on Gitea. I would like to responsibly report a potential availability-impact issue that I observed in Gitea’s Arch package registry implementation. During local testing, I noticed that Gitea records non-dot regular file entries...
