Impact fast-uri v4.1.0 and earlier do not treat a literal backslash (U+005C) as an authority delimiter. Node's native WHATWG URL (used by fetch(), undici, and Node's http/https clients) normalizes \ to / for special schemes (http, https, ws, wss, ftp, file), so the two parsers e…
Impact A number of vulnerabilities, two rated as "High" severity using CVSSv4, have been discovered and fixed in the upstream libvips dependency. Those processing untrusted input with versions of sharp prior to 0.35.0 are affected. Patches Using prebuilt binaries provided by …
Impact fast-xml-parser processes multiple "DOCTYPE" declarations within a single XML document. Each declaration passes its entities to @nodable/entities through addInputEntities(). addInputEntities() resets the entity expansion counters every time it is called. An attacker can t…
Summary Repo.clone_from() passes the caller-supplied remote URL through Git.polish_url(), which on every non-Cygwin platform calls os.path.expandvars() on the URL before handing it to git clone. An attacker who controls the URL argument — the documented use case for clone_from() …
Summary There is a possible cross-site scripting vulnerability in rails-html-sanitizer when the sanitizer is configured to allow an SVG reference element such as <use>. See related GHSA-9wjq-cp2p-hrgf in Loofah, whose SVG local-reference logic rails-html-sanitizer mirrors. - Ve…
Summary A WebSocket upgrade request to an upgradeWebSocket route with a missing or malformed Sec-WebSocket-Key header leaks memory permanently. The request's IncomingMessage is retained in an internal map and a pending promise is never settled, even though no connection is estab…
Multiple security vulnerabilities have been identified and addressed in grpc-go affecting the xDS RBAC authorization engine (internal/xds/rbac) and the HTTP/2 transport server implementation (internal/transport). These vulnerabilities could result in: - Authorization Bypass (Fai…
Summary Loofah::HTML5::Scrub.allowed_uri? does not correctly reject javascript: or vbscript: URIs when the scheme is split by a numeric character reference that has no trailing semicolon. A browser decodes such references and resolves the URL to an executable javascript: scheme,…
Summary Loofah's HTML5 sanitizer restricted only the xlink:href attribute on certain SVG elements to local, same-document references. Browsers also accept a plain href attribute as an alternative to the deprecated xlink:href per the SVG 2 spec, but Loofah did not apply the same …
Summary UnwrappedPropertyHandler.processUnwrapped() replays the buffered JSON for a @JsonUnwrapped property by iterating its properties and calling prop.deserializeAndSet() with no prop.visibleInView(ctxt.getActiveView()) guard — the exact guard processUnwrappedCreatorProperties(…
Summary typeorm migration:generate embeds database schema metadata into JS/TS template literals, escaping backticks but not ${...}. An attacker who can write schema metadata (column comments, defaults, view definitions) achieves arbitrary code execution on the host that loads th…
Summary The fix released in jackson-core 2.18.6 and 2.21.1 for GHSA-72hv-8253-57qq (Number Length Constraint Bypass in Async Parser, published 2026-02-28) is incomplete. The fix commit b0c428e6 (#1555) wired validateIntegerLength into a new _setIntLength helper and called it at …
Summary I'm reporting two related TOTP one-time-use defects in Gitea that survive the CVE-2021-45331 fix. The 2018 fix (PR #3878) introduced the TwoFactor.LastUsedPasscode field and added an in-memory inequality check on the web 2FA login path. That check works correctly in the …
Summary A personal access token restricted with the public-only scope can still retrieve private organization membership and organization permission details for its own account through organization-listing endpoints. This bypass breaks the intended guarantee that such tokens are …
Summary Gitea has robust SSRF protection via hostmatcher.NewDialContext() for webhook and migration clone URLs, which validates resolved IPs at the TCP dial level. However, three code paths use raw http.Get() (Go's DefaultClient) which completely bypasses this protection, enabli…
Summary The ToHook() function in services/webhook/general.go decrypts the webhook's HeaderAuthorizationEncrypted field and returns the plaintext authorization header in the API response. Any repository admin can read the full plaintext value of webhook authorization headers (Bea…

Summary GHSA-8fwc-qjw5-rvgp ("Gitea may send release notification emails for private repositories to users whose access has been revoked", fix in PR #36319 / commit 8a98ac22) added repo_model.ClearRepoWatches as a defense for the state transition public→private. The cleanup was …
Summary Gitea's /api/v1/teams/{id} API routes do not correctly enforce the public-only access token restriction. A public-only token is intended to limit API access to public repositories and public organizations. However, several team API routes continue to return private team…
Summary PR #38145 fixed ListPublicMembers and IsPublicMember but missed ListMembers. Any authenticated user can enumerate ALL members (not just public ones) of a private organization. Affected Versions <= v1.26.4 (latest) and main branch Root Cause routers/api/v1/org/member.go …
Summary The OAuth2 sign-in callback in Gitea 1.26.1 unconditionally re-enables a locally-disabled account whenever the user authenticates through a linked external identity provider, silently undoing any administrator-initiated Disable Account action and issuing a fresh authenti…
Summary An information disclosure issue in the Gitea Notification API allows users who have lost access to a private repository to continue accessing private issue or pull request information through existing notification threads. Although repository information is hidden after …
Summary Gitea 1.26.2 does not properly enforce organization visibility restrictions on organization label read endpoints. A user without access to a private organization can retrieve labels belonging to that organization through the Organization Labels API. As a result, label m…

Summary The Locale middleware that runs in front of every unauthenticated request calls golang.org/x/text/language.ParseAcceptLanguage on the raw Accept-Language header without imposing a size or shape filter. The underlying parser has quadratic-time behaviour on long lists of m…
Gitea's SSH key ingestion endpoint accepts keys in RFC 4716 (SSH2) format and normalises them before storage. The normalisation function contains an O(N²) string concatenation loop with no input size limit, meaning a single malicious key submission can force the server to perform…

Summary The AddTime API handler continues execution after an error returned by GetUserByName(). When a repository administrator specifies a non-existent user name, an error response is generated but execution does not stop. Subsequent code dereferences a nil user pointer, resul…
Summary The OIDC userinfo endpoint (GET /login/oauth/userinfo) accepts Gitea API tokens as bearer credentials but does not enforce API token scopes before returning identity claims. A personal access token scoped only to read:misc can successfully retrieve user information from…
Summary A user who previously had access to a private repository can continue to obtain repository metadata through GET /api/v1/user/starred after their access to the repository has been revoked. After a collaborator is removed from a private repository, direct access to the re…
Summary Gitea's internal API HTTP client (modules/private/internal.go) hardcodes TLSClientConfig.InsecureSkipVerify = true with no configuration override. It is the only outbound TLS client in the codebase that cannot be made to verify its peer's certificate — webhook, migration…
Summary The endpoint "/orgs/{org}/public_members/{username}" + GET exposes organization membership of public members in a private organization. PoC 1. Spin up the nightly container of Gitea. 2. Perform the default installation. 3. Register a new user (let's call this user "use…
Summary Gitea's RSS/Atom feed handlers accept API-token Basic auth but perform no token-scope or public-only enforcement. A personal access token that is correctly blocked (HTTP 403) from a private repository on /raw, /media, /archive, and /releases/download/... — because it is …
Summary GetActionsUserRepoPermission (models/perm/access/repo_permission.go) decides whether an Actions task token may access a target repo. Its cross-repo branches each enforce a fork-PR discriminator — except the collaborative-owner branch, which is missing the !task.IsForkPul…
Summary An unbounded io.ReadAll(ctx.Req.Body) call in the NPM package tag API endpoint allows any authenticated user to crash the Gitea server by sending a single large HTTP request. The request body is read entirely into memory with no size limit, causing an Out-of-Memory (OOM) …
Summary The API endpoint DELETE /repos/{owner}/{repo}/issues/{index}/labels/{id} loads the label by ID with a global, unscoped lookup and never verifies the label belongs to the URL's repository (or its owning organization). Because the response status differs by whether the lab…
Summary A personal access token (PAT) or OAuth2 token that does not carry the repository scope or that is public-only is correctly rejected (HTTP 403) by the recently hardened web content routes (archive download, raw/media file download, and repository RSS/Atom feeds). However, …
Summary Gitea allows a public-only,write:repository token to update a private pull request head branch through a public base repository route. The vulnerable endpoint is: POST /api/v1/repos/{public-owner}/{public-repo}/pulls/{index}/update Gitea checks the token's public-only …
Summary Gitea's repository migration URL validation can be bypassed when a migration hostname resolves to multiple IP addresses. The validation logic accepts the destination if any resolved IP is allowed, even if another resolved IP is loopback, private, or otherwise blocked. Th…
Summary Gitea's restore-repo CLI command restores a repository from a dump directory/archive. When parsing pull_request.yml from that dump, the Head.CloneURL field is used to add a git remote and fetch from it with no validation, because the safety check that's supposed to guard …
Details RemoveDependency in routers/web/repo/issue_dependency.go takes a removeDependencyID form parameter identifying the other issue by its global numeric ID, and fetches it with issues_model.GetIssueByID(ctx, depID) - no repository or permission check at all. It then calls iss…
Summary Gitea Actions Artifacts V4 signed upload/download URLs can be rewritten to access a different running task and repository context while preserving the original HMAC signature. An attacker with permission to run a Gitea Actions job can turn a signed URL for an attacker-co…
