### Summary MCP SSE redirects could forward Authorization headers. In affected versions, a lower-trust caller or configured input path could execute or persist actions beyond the caller's intended authorization. This advisory is scoped to the named feature and configuration. It does not change OpenClaw's trusted-operator model: authenticated Gateway operators, installed plugins, and intentional local execution surfaces remain trusted unless a separate policy, approval, allowlist, sandbox, or a

## Actor MCP path authority injection leaks Apify token ### Summary `@apify/actors-mcp-server` version `0.10.7` builds Actor standby URLs by directly concatenating a trusted base URL with an attacker-controlled `webServerMcpPath` value taken from an Actor definition returned by the Apify API. An attacker who publishes a malicious Actor with a crafted `webServerMcpPath` (e.g., `@attacker.example/mcp`) can cause the MCP client to resolve the final URL to an entirely different host. Because the M

# Share-link `?token=…` redemption races past download limit **Ecosystem:** Go **Package:** `goshs.de/goshs/v2` (`github.com/patrickhener/goshs`) **Affected:** `<= v2.0.9` (every release that shipped the share-link feature) ## Summary `ShareHandler` reads the share token's `DownloadLimit` under `RLock`, releases the lock, serves the file, then re-acquires the lock to increment the counter. Concurrent requests all read the same `Downloaded`/`DownloadLimit` snapshot, all pass the check, and all

### Impact When Ghost is behind a shared caching layer that results in cached content being shared between different visitors (e.g., Fastly, Cloudflare, nginx proxy_cache, and others), an unauthenticated user could send an `x-ghost-preview` header that altered the rendered frontend response. In affected cache configurations, that response could be stored and served to subsequent visitors requesting the same page, allowing cache poisoning of request-specific preview output. When running Ghost'

# WebDAV listener ignores `--read-only`, `--upload-only`, and `--no-delete` mode flags **Ecosystem:** Go **Package:** `goshs.de/goshs/v2` (`github.com/patrickhener/goshs`) **Affected:** `<= v2.0.9` (every release that ships the WebDAV handler) ## Summary When `goshs` is launched with WebDAV enabled (`-w`), the mode-restriction flags `--read-only`, `--upload-only`, and `--no-delete` are enforced only on the primary HTTP port. The WebDAV port is wired straight to `golang.org/x/net/webdav.Handle

# ORAS Go forwards registry credentials across registry redirects Reporter / public credit: JUNYI LIU ## Summary ORAS Go can forward registry credentials configured for one registry origin to a different HTTP origin during registry redirects. There are two related paths: 1. A manifest or metadata request authenticates to the origin registry, then the origin returns a redirect to another host or port. The redirected request can carry the origin `Authorization` header to the redirect target.

## Summary A flaw in `com.ongres.scram:scram-client` allows an attacker capable of performing a TLS man-in-the-middle (MITM) attack to silently downgrade a connection from `SCRAM-SHA-256-PLUS` (with channel binding) to standard `SCRAM-SHA-256` (without channel binding), bypassing strict client-side enforcement policies. ## Component Breakdown This occurs due to a two-part failure in `TlsServerEndpoint` when a server presents an `X.509` certificate using a modern signature algorithm that lacks

### Root cause The tar-extraction helper `ensureLinkPath` at [`content/file/utils.go:262-275`](https://github.com/oras-project/oras-go/blob/main/content/file/utils.go#L262-L275) validates that a hardlink's target resolves inside the extract base, but then returns the original unresolved `target` string back to the caller: ```go func ensureLinkPath(baseAbs, baseRel, link, target string) (string, error) { path := target if !filepath.IsAbs(target) { path = filepath.Join(filepath.D

The file content store in `oras-go` attempts to confine writes to `workingDir` when `AllowPathTraversalOnWrite=false`, but the guard is lexical and does not account for symlink traversal. If `workingDir` contains a symlink path component and an attacker-controlled blob title (via `ocispec.AnnotationTitle`) targets a path under that symlink, `pushFile()` can create a file outside `workingDir`. ## relevant links - repository: https://github.com/oras-project/oras-go - commit: 03243809936cce826494

The massive FortiBleed credential theft campaign has been linked to the INC and Lynx ransomware operations, suggesting the stolen Fortinet credentials were intended to fuel future network intrusions. [...]

## Summary oras-go follows a registry-controlled `Location` header during the monolithic blob upload flow and reuses the `Authorization` header from the initial `POST` request for the subsequent `PUT` request. If a malicious registry returns a cross-host `Location`, oras-go can send the caller's credentials to an attacker-controlled endpoint. ## Affected Versions tested: v2.6.0 (commit 03243809936cce826494b5506f724c6dc11115b1, as-of 2026-01-24) range: unknown; likely affects earlier v2.x rele

### Description A flaw was found in Keycloak's Fine-Grained Admin Permissions (FGAPv2) feature. An administrator with limited client management permissions can exploit this vulnerability to assign any realm role, including highly privileged roles, to a client's scope mapping. This bypasses intended security controls, allowing the injected role to be projected into a user's authentication token when they access the modified client. This could lead to unauthorized privilege escalation within the K

Heap-based buffer overflow in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally.

Improper neutralization of input during web page generation ('cross-site scripting') in Microsoft Entra ID allows an authorized attacker to perform spoofing over a network.
