Summary Gitea 1.25.4 validates the initial URL provided to the repository migration endpoint (POST /api/v1/repos/migrate) and correctly blocks requests to internal addresses like 127.0.0.1 or RFC1918 ranges. However, if the initial URL points to an attacker-controlled server tha…
Summary A Gitea personal access token (PAT) restricted to a non-repository scope (e.g. read:issue) can read the commit history of any private repository the token owner can access, via the repository RSS/Atom feed endpoints. The same token is correctly denied (403) on /raw, /medi…
Summary A user with Code write access to one repository may be able to associate an existing Git LFS object from a private source repository with their target repository, even when they do not have Code access to the source repository that currently owns the LFS object. The iss…
Summary The Gitea Docker images ship an app.ini template that hard-codes: REVERSE_PROXY_TRUSTED_PROXIES = * The documented default for this setting, in custom/conf/app.example.ini, is 127.0.0.0/8,::1/128, i.e. only loopback is trusted. When an admin enables ENABLE_REVERSE_PRO…
Summary Gitea's default SSRF allow-list (MatchBuiltinExternal, used by both webhook delivery and repository migrations) relies on Go's standard library net.IP.IsPrivate(), which only covers RFC 1918 and RFC 4193. As a result, several IP ranges commonly used for cloud metadata se…
Summary The API endpoint used to fork repositories into organizations performs a weaker authorization check than the corresponding web UI and other repository creation endpoints. When a repository is forked into an organization through the API, the endpoint only verifies that t…
Gitea's API endpoint for creating Personal Access Tokens (POST /users/{username}/tokens) is protected by a middleware (reqBasicOrRevProxyAuth) that is intended to require password-based authentication, preventing a compromised token from being used to mint new ones. However, when…
Gitea's Debian package registry parser contains an unbounded decompression vulnerability in ParseControlFile. When processing an uploaded .deb file, the parser decompresses control.tar.gz and copies the entire uncompressed stream into a strings.Builder via a TeeReader, with no li…

Summary Gitea's draft-release access control is enforced only on the API release endpoints (/api/v1/repos/{owner}/{repo}/releases/{id} and its /assets/... sub-routes) but not on the web-level UUID-based attachment endpoints (/attachments/{uuid}, /{owner}/{repo}/attachments/{uuid…
Summary The web handler EditReleasePost (routers/web/repo/release.go) reads form fields with prefix attachment-edit-{uuid} into a map[uuid]newName, passes that map to release_service.UpdateRelease, which writes the new name to the database via repo_model.UpdateAttachmentByUUID W…
Summary After PR #37118 / CVE-2026-25714 (fix: Unify public-only token filtering in API queries and repo access checks, merged 2026-05-18, backport #37773 to 1.26.2 — the May 2026 unification pass for public-only token filtering, reporter Medoedus per the 1.26.2 release notes), …
Summary Gitea does not re-evaluate the official flag on existing pull request reviews when a PR's target branch is changed. An attacker with write access to a repository can obtain an official: true approval on a PR targeting an unprotected branch, then retarget the PR to a prot…
Summary CVE-2026-20800 fixed private-info leakage to revoked users only for the notification endpoint. Two sibling endpoints that return data keyed on the caller's own relationship still do not re-check repo access at output time: - GET /api/v1/user/starred — getStarredRepos() co…
Affected product Gitea — services/repository/collaboration.go (DeleteCollaboration) + webhook delivery Summary When a collaborator with admin permission on a private repo creates a webhook, that webhook keeps firing after the collaborator's access is revoked. Gitea's revocation …
Summary GitPython spawns the real git binary with an argument vector built from caller-supplied values. To prevent argument injection, GitPython maintains denylists of "unsafe" Git options (--upload-pack, --receive-pack, --exec, -c, --config, …) that can be abused to run arbitra…
Bulletin ID: 2026-061-AWS Scope: AWS Content Type: Important (requires attention) Publication Date: 07/21/2026 12:45 PM PDT Description: Smithy-RS is a Rust code generation and runtime framework that generates HTTP clients and servers from Smithy interface definitions, powering t…
Command injection via long-option prefix abbreviation bypassing check_unsafe_options (incomplete fix of CVE-2026-42215 / GHSA-rpm5-65cw-6hj4) Component: gitpython-developers/GitPython (PyPI: GitPython) Affected: all versions carrying the 3.1.47 blocklist fix, through current mai…
GitPython version 3.1.50 blocks unsafe git clone options such as --upload-pack, -u, --config, and -c unless callers explicitly pass allow_unsafe_options=True. However, the default unsafe-option gate does not recognize joined short-option forms such as -u/path/to/helper. Git itse…
Summary SVGO's removeScripts plugin (disabled by default) removes scripts from the SVG, however executable scripts were left intact in some cases. If a consumer relied on this plugin for sanitization and served them to users, these SVGs could open up doors to XSS. Details SVGO…
Summary There is a possible hook-policy inconsistency in DOMPurify 3.4.11 involving CUSTOM_ELEMENT_HANDLING. When a custom element is allowed via CUSTOM_ELEMENT_HANDLING.tagNameCheck, it appears that the element does not go through afterSanitizeElements in the same way as a nor…
Summary In BeanDeserializer.deserializeUsingPropertyBasedWithExternalTypeId, the active-view (@JsonView) filter was applied only to the regular bean-property branch; the creator-property branch performed no creatorProp.visibleInView(activeView) check. A constructor parameter ann…
Summary Browser Mode exposes a set of built-in "commands" that run on the Node.js side of the test runner and can touch the local filesystem (taking screenshots, managing Playwright traces, uploading files for <input type="file">, comparing screenshots). Several of these comman…
Impact This is a credential-exposure / credential-confusion issue. getRegistryCredentials() reads credentials from the Docker config file (~/.docker/config.json) and selects an entry by checking whether any configured auth key contains the target registry string: Object.keys(d…
Summary For Java Records, POJOPropertiesCollector._removeUnwantedIgnorals() records a @JsonIgnore-annotated component under its original implicit name before _renameUsing() applies the PropertyNamingStrategy. After the rename, _ignoredPropertyNames still holds only the pre-rename…

Repository Migration Follows Git HTTP Redirects After URL Allow/Block Validation, Enabling Internal Git Repository Exfiltration Summary Gitea validates the user-supplied repository migration URL, but the actual clone and later mirror fetch operations are performed by the Git co…
Impact The univ.Real type converted its (mantissa, base, exponent) value to a Python float using exact big-integer exponentiation. A BER/CER/DER-encoded REAL value only a few bytes long can carry a very large exponent, causing this computation to attempt to materialize an astrono…
Impact The BER/CER/DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs. A small crafted payload (tens of kilobytes) containing an OID with many arcs consumes seconds of CPU per decode() call, allowing denial of service i…
Impact The BER decoder (shared by the CER and DER codecs) parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadrati…
Summary When building a source distribution (python -m build --sdist / setup.py sdist), setuptools' FileList applies MANIFEST.in directives (exclude, global-exclude, recursive-exclude, prune) by matching a compiled glob against on-disk file names byte-for-byte, with no Unicode n…
Summary @opentelemetry/propagator-jaeger decodes incoming HTTP header values with decodeURIComponent() without handling decode errors. A single request carrying a malformed percent-encoded value (for example a bare %) in an uber-trace-id or uberctx-* header throws an uncaught UR…
Summary linkify-it's schema-scan loop (.test() / .match(), the documented public API) invokes the mailto: schema validator at every mailto: occurrence in the input text. For each occurrence the validator does text.slice(pos) (an O(n) copy) and runs an email regex whose local-part…
Summary AWS CDK (aws-cdk-lib) is an open-source framework for defining cloud infrastructure in code and provisioning it through AWS CloudFormation. OS command injection issue in the NodejsFunction Docker bundling pipeline in aws-cdk-lib before 2.260.0 that might allow an actor wh…
Impact fast-uri versions >= 2.3.1, <= 4.0.0 fail to canonicalize Unicode/IDN hostnames for HTTP-family URLs. The IDN conversion path calls URL.domainToASCII(...) on the global WHATWG URL constructor, where that helper does not exist. The resulting TypeError is silently routed in…
Summary Immutable.Map and Immutable.Set keep keys that share the same 32-bit hash in a collision bucket that is scanned linearly. The string hash is public and deterministic, so an attacker who controls the keys inserted into a Map can craft many keys that all collide, degrading…
Summary List#set, List#setSize, List#setIn, List#updateIn (and the functional set / setIn / updateIn) mishandle an index or size in the range [2 30, 2 31): - On an empty List the operation enters an uncatchable infinite loop (a tight CPU spin; a surrounding try/catch never rega…
Impact guzzlehttp/psr7 did not reject URI host components containing authority delimiters (/, ?, #, @, or \), an embedded port such as host:8080, or IPv6 brackets that do not frame the host (such as [::1 or ::1]). Uri::assertValidHost() rejected only control characters, so these…

Impact If this library is used to implement a WebSocket server on top of a TCP server, by using the WebSocket::Driver.server() method, then a client can cause the server to crash by sending a Host header that is not a valid host[:port] string. When this happens, a URI::InvalidUR…
Summary hono/jsx did not isolate context values per request during server-side rendering. While an async component was suspended on await, its provided context value stayed observable to other requests rendering concurrently, so useContext() could return a value from a different…
Summary cx() in hono/css composes class names from plain strings but marks the result as already-escaped without HTML-escaping the input. When the result is used as a JSX class attribute during server-side rendering, the value is written into the attribute unescaped, so untruste…
Summary The AWS API Gateway v1 adapter can drop a distinct repeated request header value. When a header appears multiple times, the adapter de-duplicates values using a substring comparison instead of an exact match, so a value that is a substring of another value of the same he…
The same as the hono core Path traversal in serve-static on Windows via encoded backslash (%5C). Summary On Windows hosts, an encoded backslash (%5C) in the request path decodes to \, which the Windows path resolver treats as a separator. serve-static then resolves a single URL…
