Title
Penpot: SSRF guard bypass via IPv6 transition addresses (NAT64/6to4/Teredo) in webhook delivery and media download
Summary
Penpot is an open-source design and prototyping platform. Prior to 2.18.0, app.util.ssrf/blocked-address? relies on Java InetAddress predicates that do not classify NAT64, 6to4, or Teredo addresses and applies additional CIDR checks only to IPv4 values. Exploitation requires routing through a NAT64 gateway or an attacker-controlled DNS AAAA record; cloud environments with NAT64 gateways are directly exploitable. A user controlling a media import URL, or an administrator controlling a webhook URL, can then supply an IPv6 transition address that embeds a cloud-metadata, loopback, link-local, or private IPv4 target and bypasses the intended SSRF restrictions. Media import can disclose response bodies, while webhook delivery can expose response status as a network-probing side channel. This issue is fixed in version 2.18.0.

Title
Ghost: Private IP Filtering Bypass via IPv6 Transition Addresses
Summary
Ghost is a Node.js content management system. From 6.0.9 until 6.65.0, a validation issue allowed some functionality, such as Webmentions, to be abused by an unauthenticated user to make limited HTTP requests to hosts in the Ghost server's internal network on some network configurations. A successful attack would not result in any response data being returned. This issue is fixed in version 6.65.0.

Title
Ghost: Server-Side Request Forgery in Bookmark Fetching
Summary
Ghost is a Node.js content management system. From 6.54.1 until 6.65.0, a validation issue allowed some functionality, such as Webmentions, to be abused by an unauthenticated user to make limited HTTP requests to hosts in the Ghost server's internal network. A successful attack would not result in any response data being returned. This issue is fixed in version 6.65.0.

CVE-2026-105636 (GCVE-0-2026-105636)

Vulnerability from cvelistv5 – Published: 2026-10-05 18:02 – Updated: 2026-10-07 21:39

Title
Plane: SSRF via HTTP redirect in webhook delivery (allow_redirects not set)
Summary
Plane is an open-source project management tool. Prior to 1.4.0, the webhook delivery task in apps/api/plane/bgtasks/webhook_task.py calls requests.post() without allow_redirects=False and does not validate redirect targets. validate_url() blocks private, loopback, link-local, and reserved addresses in the original webhook URL, but the final URL reached after one or more redirects is not checked. A user who can create a workspace can register a webhook pointing to an attacker-controlled public endpoint that returns a 302 redirect to an internal address. The Plane worker then fetches internal resources, including cloud metadata, and stores the response body in webhook_logs, where the attacker can retrieve it through the workspace webhook-logs API. This issue is fixed in 1.4.0.

CVE-2026-105628 (GCVE-0-2026-105628)

Title
Plane: OAuth Avatar Redirect SSRF Leads to Internal Data Exfiltration via Static Asset Endpoint
Summary
Plane is an open-source project management tool. Prior to 1.4.0, Plane's OAuth avatar synchronization flow fetches avatar_url from provider user data through a server-side HTTP request without internal IP validation and follows redirects by default. An attacker can provide an avatar URL that redirects to an internal-only resource, such as a metadata endpoint, and Plane uploads the fetched response as a user avatar file. The object is then exposed through /api/assets/v2/static/{asset_id}/, allowing exfiltration of internally fetched content. This issue is fixed in 1.4.0.

Title
O2OA General url ActionUploadExcelWithUrl server-side request forgery
Summary
A flaw has been found in O2OA up to 10.0.1-ce. This affects the function ActionUploadExcelWithUrl of the file /x_general_assemble_control/jaxrs/excel/upload/with/url of the component General Module. Executing a manipulation of the argument fileUrl can lead to server-side request forgery. The attack can be launched remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.

This candidate was rejected after further investigation determined that it is not a security vulnerability. The client certificate chain is validated during mTLS negotiation at the TLS layer or reverse proxy before Keycloak processes CRL Distribution Point or OCSP URLs, so only certificates issued by a CA explicitly trusted by the administrator can trigger these requests.

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.
