CWE-918

Allowed

Server-Side Request Forgery (SSRF)

CVE-2026-18424 (GCVE-0-2026-18424)

Title
Concrete CMS 9.0.0 to 9.5.2 is vulnerable to SSRF protection bypass in remote file import when multiple URLs share a host but use different ports
Summary
Concrete CMS 9.0.0 to 9.5.2 is vulnerable to Server-Side Request Forgery iremote file import via cross-port reuse of a host's validated DNS pin. When multiple remote URLs share the same host, only the first `ValidatedRemoteUrl` is retained and reused for every later URL with that host. A low-privileged authenticated user permitted to import files could therefore supply a DNS-rebinding host that resolved to a public address during validation and to a private or loopback address during the unpinned download, causing the server to fetch internal-only resources such as loopback services, internal admin panels, or cloud metadata endpoints and to save the responses into the file manager. The Concrete CMS security team gave this vulnerability a CVSS v4.0 score of 2.1 with vector CVSS:4.0/AV:N/AC:H/AT:P/PR:H/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N.

Title
Project-koku/koku-metrics-operator: koku-metrics-operator: service-account client credentials sent to user-controlled token_url
Summary
A flaw was found in koku-metrics-operator. The operator's CostManagementMetricsConfig custom resource allows a user able to edit the CR to specify an arbitrary OAuth token endpoint. When authentication.type is set to service-account, the operator sends the tenant's Red Hat SSO client_id and client_secret to this user-controlled URL, allowing the attacker to obtain the credentials.

Title
Project-koku/koku-metrics-operator: koku-metrics-operator: operator service-account token exfiltration via user-controlled prometheus service_address
Summary
A flaw was found in the koku-metrics-operator for Red Hat OpenShift. The operator's CostManagementMetricsConfig custom resource allows a user able to edit the CR to specify an arbitrary upload URL. The operator attaches its own Kubernetes service-account bearer token to queries sent to this user-controlled URL, allowing the attacker to obtain the token.

CVE-2026-18378 (GCVE-0-2026-18378)

Vulnerability from cvelistv5 – Published: 2026-07-30 12:00 – Updated: 2026-10-12 20:41

Title
Project-koku/koku-metrics-operator: koku-metrics-operator: cluster pull-secret token exfiltration via user-controlled api_url (ssrf / confused deputy)
Summary
A flaw was found in koku-metrics-operator. The operator's CostManagementMetricsConfig custom resource allows user able to edit the CR to specify an arbitrary upload URL. When authentication.type is set to token (the default), the cluster-global Red Hat Cloud pull-secret bearer token is attached to HTTP requests sent to this user-controlled URL, allowing the attacker to obtain the token.

CVE-2026-18369 (GCVE-0-2026-18369)

Vulnerability from cvelistv5 – Published: 2026-07-30 10:32 – Updated: 2026-11-05 19:25

Title
Dogtag-pki: pki-core: redhat-pki: pki: acme http-01 validation ssrf via ip literal identifiers and unvalidated redirects
Summary
A flaw was found in Dogtag PKI's ACME responder where the HTTP-01 challenge validator accepts IP address literals as dns identifiers and follows HTTP redirects without validating that the target is a public address. An unauthenticated ACME account holder can exploit this to perform server-side request forgery (SSRF), making the Dogtag server send HTTP GET requests to internal network services. With the InMemory database backend, the response body of internal targets is disclosed to the attacker through the ACME challenge error.

Title
Server-Side Request Forgery (SSRF) in eScriptorium
Summary
Server-side request forgery in the METS and IIIF import URI handling in Scripta eScriptorium through 26.04.1 allows a remote authenticated user to make the server issue arbitrary HTTP requests to internal hosts, including the cloud instance metadata service, via the mets_uri or iiif_uri parameter of POST /api/documents/{pk}/imports/, because the IMPORT_ALLOWED_DOMAINS setting defaults to '*' and no address filtering, redirect cap or timeout is applied

CVE-2026-18353 (GCVE-0-2026-18353)

Vulnerability from cvelistv5 – Published: 2026-07-30 07:23 – Updated: 2026-07-30 13:02

Title
Unauthenticated SSRF in PIA via OIDC issuer allowlist bypass
Summary
PIA's `POST /v1/upload/sbom` endpoint accepts a Bearer JWT and checks its **unverified** `iss` claim against an issuer allowlist using Python's `urlparse` before performing OIDC discovery with `requests`. Because `urlparse` and `requests`/`urllib3` parse an authority string containing a backslash (e.g. `https://attacker-host\@ci.eclipse.org/`) into *different* hostnames, an attacker can craft an issuer that passes the allowlist check yet drives `requests` — and subsequently `urllib.request.urlopen` for JWKS retrieval — to connect to an arbitrary attacker-chosen host, port, and scheme.

Title
Kirki – Freeform Page Builder, Website Builder & Customizer <= 6.2.0 - Unauthenticated Blind Server-Side Request Forgery via 'kirki_data' Parameter
Summary
The Kirki – Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Blind Server-Side Request Forgery in all versions up to, and including, 6.2.0 via the 'kirki_data' Parameter. This makes it possible for unauthenticated attackers to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

CAPEC-664: Server Side Request Forgery

An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
