LinkWarden: Server-Side Request Forgery (SSRF) in Link Creation via fetchTitleAndHeaders Function

Linkwarden is a self-hosted, open-source collaborative bookmark manager to collect, organize and archive webpages. Prior to version 2.13.0, a Server-Side Request Forgery (SSRF) vulnerability in the fetchTitleAndHeaders function allows authenticated users to make arbitrary HTTP requests to internal services due to insufficient URL validation that only checks for "http://" or "https://" prefixes. This issue has been patched in version 2.13.0.

Soft Serve: SSRF via unvalidated LFS endpoint in repo import

Soft Serve is a self-hostable Git server for the command line. From version 0.6.0 to before version 0.11.4, an authenticated SSH user can force the server to make HTTP requests to internal/private IP addresses by running repo import with a crafted --lfs-endpoint URL. The initial batch request is blind (the response from a metadata endpoint won't parse as valid LFS JSON), but an attacker hosting a fake LFS server can chain this into full read access to internal services by returning download URLs that point at internal targets. This issue has been patched in version 0.11.4.

Spinnaker clouddriver and orca URL validation bypass via underscores in hostnames

### Impact Spinnaker updated URL Validation logic on user input to provide sanitation on user inputted URLs for clouddriver. However, they missed that Java URL objects do not correctly handle underscores on parsing. This led to a bypass of the previous CVE (CVE-2025-61916) through the use of carefully crafted URLs. Note, Spinnaker found this not just in that CVE, but in the existing URL validations in Orca fromUrl expression handling. This CVE impacts BOTH artifacts as a result. ### Patches This has been merged and will be available in versions 2025.4.1, 2025.3.1, 2025.2.4 and 2026.0.0. ### Workarounds You can disable the various artifacts on this system to work around these limits.

LibreChat is vulnerable to Server-Side Request Forgery due to missing restrictions

LibreChat is a ChatGPT clone with additional features. Version 0.8.1-rc2 is prone to a server-side request forgery (SSRF) vulnerability due to missing restrictions of the Actions feature in the default configuration. LibreChat enables users to configure agents with predefined instructions and actions that can interact with remote services via OpenAPI specifications, supporting various HTTP methods, parameters, and authentication methods including custom headers. By default, there are no restrictions on accessible services, which means agents can also access internal components like the RAG API included in the default Docker Compose setup. This issue is fixed in version 0.8.1-rc2.
