Title
Mastodon Server-Side Request Forgery vulnerability
Summary
Mastodon is a free, open-source social network server based on ActivityPub. Starting in version 4.2.0-beta1 and prior to version 4.2.0-rc2, by crafting specific input, attackers can inject arbitrary data into HTTP requests issued by Mastodon. This can be used to perform confused deputy attacks if the server configuration includes `ALLOWED_PRIVATE_ADDRESSES` to allow access to local exploitable services. Version 4.2.0-rc2 has a patch for the issue.

Title
GeoNode SSRF Bypass to return internal host data
Summary
GeoNode is an open source platform that facilitates the creation, sharing, and collaborative use of geospatial data. A SSRF vulnerability exists starting in version 3.2.0, bypassing existing controls on the software. This can allow a user to request internal services for a full read SSRF, returning any data from the internal network. The application is using a whitelist, but the whitelist can be bypassed. The bypass will trick the application that the first host is a whitelisted address, but the browser will use `@` or `%40` as a credential to the host geoserver on port 8080, this will return the data to that host on the response. Version 4.1.3.post1 is the first available version that contains a patch.

Title
Partial Server-Side Request Forgery in Home Assistant Core
Summary
Home assistant is an open source home automation. In affected versions the `hassio.addon_stdin` is vulnerable to a partial Server-Side Request Forgery where an attacker capable of calling this service (e.g.: through GHSA-h2jp-7grc-9xpp) may be able to invoke any Supervisor REST API endpoints with a POST request. An attacker able to exploit will be able to control the data dictionary, including its addon and input key/values. This issue has been addressed in version 2023.9.0 and all users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as GitHub Security Lab (GHSL) Vulnerability Report: `GHSL-2023-162`.

Title
Unsecured WMS dynamic styling sld=<url> parameter affords blind unauthenticated SSRF in GeoServer
Summary
GeoServer is an open source software server written in Java that allows users to share and edit geospatial data. The WMS specification defines an ``sld=<url>`` parameter for GetMap, GetLegendGraphic and GetFeatureInfo operations for user supplied "dynamic styling". Enabling the use of dynamic styles, without also configuring URL checks, provides the opportunity for Service Side Request Forgery. This vulnerability can be used to steal user NetNTLMv2 hashes which could be relayed or cracked externally to gain further access. This vulnerability has been patched in versions 2.22.5 and 2.23.2.

Title
Controlled SSRF through URL in the WireMock
Summary
WireMock is a tool for mocking HTTP services. WireMock can be configured to only permit proxying (and therefore recording) to certain addresses. This is achieved via a list of allowed address rules and a list of denied address rules, where the allowed list is evaluated first.
Until WireMock Webhooks Extension 3.0.0-beta-15, the filtering of target addresses from the proxy mode DID NOT work for Webhooks, so the users were potentially vulnerable regardless of the `limitProxyTargets` settings. Via the WireMock webhooks configuration, POST requests from a webhook might be forwarded to an arbitrary service reachable from WireMock’s instance. For example, If someone is running the WireMock docker Container inside a private cluster, they can trigger internal POST requests against unsecured APIs or even against secure ones by passing a token, discovered using another exploit, via authentication headers. This issue has been addressed in versions 2.35.1 and 3.0.3 of wiremock. Wiremock studio has been discontinued and will not see a fix. Users unable to upgrade should use external firewall rules to define the list of permitted destinations.

Title
LibreY Server-Side Request Forgery (SSRF) vulnerability via wikipedia_language cookie
Summary
LibreY is a fork of LibreX, a framework-less and javascript-free privacy respecting meta search engine. LibreY is subject to a Server-Side Request Forgery (SSRF) vulnerability in the `engines/google/text.php` and `engines/duckduckgo/text.php` files in versions before commit be59098abd119cda70b15bf3faac596dfd39a744. This vulnerability allows remote attackers to request the server to send HTTP GET requests to arbitrary targets and conduct Denial-of-Service (DoS) attacks via the `wikipedia_language` cookie. Remote attackers can request the server to download large files to reduce the performance of the server or even deny access from legitimate users. This issue has been patched in https://github.com/Ahwxorg/LibreY/pull/9. LibreY hosters are advised to use the latest commit. There are no known workarounds for this vulnerability.

Summary
LibreY is a fork of LibreX, a framework-less and javascript-free privacy respecting meta search engine. LibreY is subject to a Server-Side Request Forgery (SSRF) vulnerability in the `image_proxy.php` file of LibreY before commit 8f9b9803f231e2954e5b49987a532d28fe50a627. This vulnerability allows remote attackers to use the server as a proxy to send HTTP GET requests to arbitrary targets and retrieve information in the internal network or conduct Denial-of-Service (DoS) attacks via the `url` parameter. Remote attackers can use the server as a proxy to send HTTP GET requests and retrieve information in the internal network. Remote attackers can also request the server to download large files or chain requests among multiple instances to reduce the performance of the server or even deny access from legitimate users. This issue has been addressed in https://github.com/Ahwxorg/LibreY/pull/31. LibreY hosters are advised to use the latest commit. There are no known workarounds for this vulnerability.

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.
