GHSA-CWC7-Q2Q7-QMR2

Vulnerability from github – Published: 2026-01-14 06:30 – Updated: 2026-01-14 06:30
VLAI
Details

The GetContentFromURL plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 1.0. This is due to the plugin using wp_remote_get() instead of wp_safe_remote_get() to fetch content from a user-supplied URL in the 'url' parameter of the [gcfu] shortcode. This makes it possible for authenticated attackers, with Contributor-level access and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

Vulnerability from github – Published: 2026-04-30 17:28 – Updated: 2026-05-08 21:47
VLAI
Summary
Weblate Vulnerable to Authenticated SSRF via Project Backup Import bypassing validate_repo_url
Details

Impact

An authenticated user with project.add permission (default on hosted Weblate SaaS and for any user holding an active billing/trial plan) can import a crafted project backup ZIP whose components/<name>.json contains an attacker-chosen repo URL pointing at a private address (e.g. http://127.0.0.1:9999/) or using a non-allow-listed scheme (e.g. file://, git://). Weblate persists the component via Component.objects.bulk_create([component])[0], which bypasses Django's full_clean() and therefore never runs the validate_repo_url validator. The URL is subsequently written verbatim into .git/config by configure_repo(pull=False).

Summary
Statamic Vulnerable to Server-Side Request Forgery via Glide
Details

Impact

When Glide image manipulation is used in insecure mode (which is not the default), the image proxy can be abused by an unauthenticated user to make the server send HTTP requests to arbitrary URLs—either via the URL directly or via the watermark feature. That can allow access to internal services, cloud metadata endpoints, and other hosts reachable from the server.

Patches

This has been fixed in 5.73.11 and 6.4.0.

VLAI
Details

A vulnerability was determined in prasathmani TinyFileManager up to 2.6. Affected by this vulnerability is an unknown functionality of the file /filemanager.php?p= ajax=true&type=upload of the component File Upload Handler. This manipulation of the argument uploadurl causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized. The vendor was contacted early about this disclosure but did not respond in any way.

GHSA-CXFM-5M4G-X7XP

Vulnerability from github – Published: 2021-08-25 14:47 – Updated: 2022-02-08 20:43
VLAI
Summary
A Server-Side Forgery Request can be activated unmarshalling with XStream to access data streams from an arbitrary URL referencing a resource in an intranet or the local host
Details

Impact

The vulnerability may allow a remote attacker to request data from internal resources that are not publicly available only by manipulating the processed input stream with a Java runtime version 14 to 8. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types.

Patches

If you rely on XStream's default blacklist of the Security Framework, you will have to use at least version 1.4.18.

Workarounds

See workarounds for the different versions covering all CVEs.

References

See full information about the nature of the vulnerability and the steps to reproduce it in XStream's documentation for CVE-2021-39150.

Credits

Lai Han of NSFOCUS security team found and reported the issue to XStream and provided the required information to reproduce it.

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.
