Title
HumanSignal Label Studio - Server-Side Request Forgery
Summary
A server-side request forgery vulnerability in HumanSignal Label Studio through 1.24.0.dev0 exists because SSRF_PROTECTION_ENABLED is set to false by default. The import-from-URL endpoint fetches any caller-supplied URL including internal loopback addresses on the default installation. An authenticated user can use this to reach internal services, cloud metadata endpoints, and other resources not intended for external access.

Title
Dub Dub - Server-Side Request Forgery
Summary
A server-side request forgery vulnerability in Dub as of 2026-07-10 allows unauthenticated remote attackers to make the server issue HTTP requests to arbitrary internal or external hosts via the metatags edge endpoint. The endpoint fetches any caller-supplied URL without applying a denylist or requiring authentication. An attacker can use this to scan internal services or exfiltrate data from cloud metadata endpoints.

Title
unstructured: Server-Side Request Forgery in the URL-based partitioning
Summary
The unstructured library provides open-source components for ingesting and pre-processing images and text documents, such as PDFs, HTML, Word docs, and many more. From 0.4.7 until 0.24.0, the url argument of partition, partition_html, and partition_md is fetched without host validation in unstructured/partition/auto.py, unstructured/partition/html/partition.py, and unstructured/partition/md.py. An attacker who controls that URL can make a server-side ingestion service request loopback addresses, internal HTTP services, or cloud metadata endpoints through direct targets, redirects, or DNS rebinding. The response body is returned as Element text, allowing internal response disclosure, and side-effecting GET endpoints may also be triggered. This issue is fixed in version 0.24.0.

Title
Awx: notification backends allow ssrf and credential leakage
Summary
A server-side request forgery (SSRF) vulnerability was found in multiple AWX notification backends. The webhook, Mattermost, Rocket.Chat, and Grafana notification backends use notification template URLs as direct HTTP request targets without validating the target address against private, loopback, or reserved IP ranges. An organization notification administrator can create notification templates pointing to internal or loopback addresses, causing the AWX control node to issue HTTP requests to services that are not externally accessible. Additionally, the webhook notification backend follows HTTP redirects and resends configured Basic Authentication credentials to redirect targets regardless of host change, allowing an attacker to exfiltrate notification credentials by redirecting to an attacker-controlled host. The Grafana backend sends its API key in the Authorization header to the configured target URL.

An organization notification administrator can create notification templates pointing to internal or loopback addresses, causing the AWX control node to issue HTTP requests to services that are not externally accessible. Additionally, the webhook notification backend follows HTTP redirects and resends configured Basic Authentication credentials to redirect targets regardless of host change, allowing an attacker to exfiltrate notification credentials by redirecting to an attacker-controlled host. The Grafana backend sends its API key in the Authorization header to the configured target URL."

Title
Awx: webhook status callback ssrf leaks the git pat
Summary
A server-side request forgery (SSRF) vulnerability was found in AWX's webhook status callback mechanism. When processing GitHub pull request webhooks, AWX extracts the status callback URL (pull_request.statuses_url) from the incoming webhook payload without validating the target host against the expected Git provider. This URL is persisted in job extra variables and later used to send authenticated status updates. A user with admin role on a webhook-enabled job template can read the template's webhook signing key, forge a signed GitHub webhook payload with an arbitrary statuses_url, and cause AWX to POST status updates to an attacker-controlled or internal URL. The status update request includes the configured Git Personal Access Token (PAT) in the Authorization header, resulting in credential leakage to the attacker-specified endpoint.

Title
Lemur: Incomplete fix for CVE-2026-55166 -- ACME authority update endpoint allows non-admin to replace `acme_url` with internal IP, bypassing allowlist
Summary
Lemur manages TLS certificate creation. Prior to 1.9.3, _validate_acme_url enforced ACME_DIRECTORY_HOST_ALLOWLIST when an authority was created, but PUT /api/1/authorities/ passed options to lemur/authorities/service.py without applying the same check. A user holding an authority role could replace the stored acme_url with an internal service or instance-metadata URL such as 169.254.169.254. The next issuance operation loaded that value and passed it to ClientV2.get_directory, causing an outbound request from the Lemur backend. This bypassed the creation-time mitigation for CVE-2026-55166 and could expose internal services or cloud metadata. The fix revalidates acme_url whenever authority options are updated. This issue is fixed in version 1.9.3.

Memos Webhook SSRF via 0.0.0.0 Reserved-IP Bypass
Summary
Memos' webhook URL validation, isReservedIP (internal/webhook/validate.go), checks a candidate IP against a reservedCIDRs list that omits 0.0.0.0/8 and never calls ip.IsUnspecified — unlike the correctly implemented sibling function isInternalIP in internal/httpgetter/html_meta.go, which does.

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.
