Blind SSRF in OAuth2 avatar synchronization via unvalidated OIDC picture claim

Gitea 1.26.2 allows fork synchronization to continue after a parent repository changes from public to private, exposing data to a fork that should no longer be authorized.

Gitea versions before 1.25.5 have insufficient permission checks for updating or rebasing pull request branches.

Public-only tokens bypass private-resource restrictions on `/api/v1/user` self routes

Gitea 1.26.2 allows unauthorized users to access labels of private organizations.

Gitea versions before 1.25.5 have insufficient visibility checks in organization permission APIs for hidden members and private organizations.

Gitea versions up to and including 1.26.1 do not apply public-only token filtering consistently to the user organization API, leaving an incomplete fix for CVE-2025-68941.

Gitea versions before 1.25.5 mishandle path resolution during template repository generation, allowing template processing to read or write through symlinked or otherwise non-regular paths.

Gitea versions up to and including 1.25.4 allow redirect bypasses through raw or percent-encoded backslashes in redirect_to values.

Gitea versions before 1.25.5 look up tracked-time entries by time ID without scoping the lookup to the issue in the request URL, allowing deletion attempts to target entries from another issue.

Gitea versions up to and including 1.26.1 allow the Allow edits from maintainers permission path to authorize commits to repositories that the user can read but should not be able to write.

Gitea versions before 1.25.5 do not consistently enforce OAuth2 authorization code expiry and single-use behavior during token exchange.

Gitea versions before 1.25.5 do not persist the OAuth2 PKCE S256 challenge method correctly during authorization, allowing token exchange without the expected verifier check.

Gitea versions before 1.25.5 do not use the migration HTTP transport for LFS push and sync mirror operations, bypassing the configured migration transport protections for those LFS requests.

Gitea versions before 1.25.5 do not enforce a timeout on git grep searches, allowing expensive searches to consume server resources.

Gitea versions before 1.25.5 allow a user to change another user's primary email address.

Gitea versions before 1.25.5 allow draft release data or attachments to be accessed without the required write permission.

Gitea versions up to and including 1.26.2 allow repository RSS and Atom feed endpoints to bypass API access token scope checks, exposing private repository commit data to tokens without the required repository scope.

Gitea versions up to and including 1.26.1 have insufficient permission checks for Composer package source links, which can expose private or internal package source information.

Gitea 1.25.5 caches a branch-specific write-permission result across multiple refs in one pre-receive hook session, allowing a per-branch maintainer-edit grant to be reused for other refs and escalate to full repository write access.

Gitea versions before 1.25.5 accept malformed or injected forwarded-proto values when detecting public URLs, allowing spoofed canonical URL generation.

Gitea versions before 1.26.0 do not fail closed on bufio.Scanner errors while processing pre-receive hook input, allowing oversized input to bypass branch-protection checks.

Gitea versions up to and including 1.26.1 do not enforce repository-unit authorization on issue-template API endpoints.

Gitea versions up to and including 1.26.1 allow OAuth2 access token scope enforcement to be bypassed through HTTP Basic authentication.

Gitea versions before 1.25.5 use release tag names and asset names as filesystem path components when dumping release assets, allowing specially crafted names to affect dump output paths.

Gitea versions from 1.25.0 before 1.26.0 allow stored cross-site scripting through the extensionsRequired field in glTF files rendered by the 3D file viewer.

Gitea versions up to and including 1.26.2 allow Git LFS object reuse to authorize private source objects for users who have repository access but lack Code-unit access.

Gitea versions up to and including 1.26.1 allow Git smart HTTP requests authenticated with bearer tokens to bypass repository token scope checks.

Gitea prior to 1.27.0 contains a server-side request forgery vulnerability that allows authenticated attackers to bypass SSRF protections by exploiting HTTP fetch operations in migration and OAuth avatar code paths that use Go's default ht…
