Technical description

swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/resolved-swagger-schema.ts warmUpRemoteSchemasCache resolves external $ref URLs and fetchRemoteSchemaDocument uses isHttpUrl to fetch any http or https target without private IP, redirect, DNS rebinding, or same-origin validation, allowing an attacker-controlled OpenAPI spec to make the generator issue requests to internal or link-local services. This issue is fixed in version 13.12.2.

———Prebid Server is an open-source solution for running real-time advertising auctions in the cloud. Prior to version 4.4.0, certain bidder adapters in Prebid Server interpolate user-supplied parameters into outbound request URLs without properly validating host and subdomain values, allowing crafted bid request parameters to cause server-side requests to unintended destinations and potentially expose internal network services or sensitive server endpoints. This issue is fixed in version 4.4.0.5h CVE-2026-546607.4 HIG

———swagger-typescript-api generates API clients for Fetch or Axios from OpenAPI specifications. Prior to 13.12.2, src/resolved-swagger-schema.ts getRemoteRequestHeaders forwards --authorizationToken to every URL fetched by fetchRemoteSchemaDocument while warmUpRemoteSchemasCache resolves external $ref URLs, allowing an attacker-controlled OpenAPI spec to exfiltrate the developer or CI bearer token to a cross-origin endpoint. This issue is fixed in version 13.12.2.6h CVE-2026-181745.3 MED

———@fastify/forwarded resolves client addresses from the X-Forwarded-For header. In versions before 3.0.2, when the header contains two or more comma separated entries, the parser trims only space characters and does not strip horizontal tabs, even though RFC 7230 defines optional whitespace as both space and tab. As a result, an entry padded with a tab keeps the literal tab in the resolved address string. Applications that make exact string match security decisions on the resolved client IP, such as an allowlist, a blocklist, a per IP rate limit key, or audit log correlation, can be evaded because the tab corrupted string no longer matches the expected value. This does not cross the trust boundary, since a tab corrupted string is not a valid IP and cannot be mistaken for a trusted proxy. The issue is fixed in @fastify/forwarded 3.0.2.5h CVE-2026-65891—

The issue also allowed existing files at the destination path to be unintentionally replaced.8h CVE-2026-60894.9 MED

——0The WP CTA plugin for WordPress is vulnerable to Server-Side Request Forgery via the 'sticky_s_media' parameter in imported JSON files in all versions up to, and including, 2.1.2. This is due to the import_sidebars() function passing user-supplied URLs from imported JSON data to file_get_contents() with only FILTER_VALIDATE_URL validation (which allows internal IPs). This makes it possible for authenticated attackers, with Administrator-level access and above, to make web requests to arbitrary locations originating from the web application, which can be used to query and modify information from internal services. The response content is saved as a WordPress media attachment, making this a full-read SSRF.6h CVE-2026-581897.5 HIG
