CVE-2024-1978Med0.295.50.00Feb 29, 2024The Friends plugin for WordPress is vulnerable to Server-Side Request Forgery in all versions up to, and including, 2.8.5 via the discover_available_feeds function. This makes it possible for authenticated attackers, with administrator-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.
CVE-2023-37978Med0.294.40.00Nov 13, 2023Server-Side Request Forgery (SSRF) vulnerability in Dimitar Ivanov HTTP Headers.This issue affects HTTP Headers: from n/a through 1.18.11.
CVE-2023-34013Med0.294.40.00Nov 13, 2023Server-Side Request Forgery (SSRF) vulnerability in Poll Maker Team Poll Maker – Best WordPress Poll Plugin.This issue affects Poll Maker – Best WordPress Poll Plugin: from n/a through 4.6.2.
CVE-2023-23684Med0.294.40.00Nov 13, 2023Server-Side Request Forgery (SSRF) vulnerability in WPGraphQL.This issue affects WPGraphQL: from n/a through 1.14.5.
CVE-2021-47958Med0.284.30.00May 15, 2026CouchCMS 2.2.1 contains a server-side request forgery vulnerability that allows authenticated attackers to make arbitrary HTTP requests by uploading malicious SVG files. Attackers can upload SVG files containing external entity references through the browse.php endpoint to access internal services and resources.
CVE-2026-41687Med0.284.30.00May 7, 2026Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.8.1, the SSRF protection in endpoints/subscription/add.php (line 42) and endpoints/payments/add.php (line 40) uses an inline IP validation check (FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE) that does not block CGNAT addresses (100.64.0.0/10, RFC 6598). The includes/ssrf_helper.php file explicitly defines is_cgnat_ip() to cover this gap (used by notification endpoints), but the logo/icon URL fetching in subscription and payment endpoints performs its own inline validation that misses this range. This allows authenticated users to perform Blind SSRF to internal services in Tailscale, Carrier-Grade NAT, and other environments using 100.64.0.0/10 addresses. This issue has been patched in version 4.8.1.
CVE-2026-36757Med0.284.30.00Apr 30, 2026A Server-Side Request Forgery (SSRF) in the /plugins/{name}/upgrade-from-uri endpoint of halo v2.22.14 allows authenticated attackers to scan internal resources via a crafted GET request.

CVE-2025-59809Med0.284.30.00Apr 14, 2026A server-side request forgery (ssrf) vulnerability [CWE-918] vulnerability in Fortinet FortiSOAR PaaS 7.6.4, FortiSOAR PaaS 7.6.0 through 7.6.2, FortiSOAR PaaS 7.5.0 through 7.5.2, FortiSOAR PaaS 7.4 all versions, FortiSOAR PaaS 7.3 all versions, FortiSOAR on-premise 7.6.4, FortiSOAR on-premise 7.6.0 through 7.6.2, FortiSOAR on-premise 7.5.0 through 7.5.2, FortiSOAR on-premise 7.4 all versions, FortiSOAR on-premise 7.3 all versions may allow an authenticated attacker to discover services running on local ports via crafted requests.
CVE-2026-34225Med0.284.30.00Apr 14, 2026Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Versions 0.7.2 and below contain a Blind Server Side Request Forgery in the functionality that allows editing an image via a prompt. The affected function performs a GET request to a user-provided URL with no restriction on the domain, allowing the local address space to be accessed. Since the SSRF is blind (the response cannot be read), the primary impact is port scanning of the local network, as whether a port is open can be determined based on whether the GET request succeeds or fails. These response differentials can be automated to iterate through the entire port range and identify open ports. If the service running on an open port can be inferred, an attacker may be able to interact with it in a meaningful way, provided the service offers state-changing GET request endpoints. This issue was unresolved at the time of publication.
CVE-2026-33534Med0.284.30.01Apr 13, 2026EspoCRM is an open source customer relationship management application. Versions 9.3.3 and below have an authenticated Server-Side Request Forgery (SSRF) vulnerability that allows bypassing the internal-host validation logic by using alternative IPv4 representations such as octal notation (e.g., 0177.0.0.1 instead of 127.0.0.1). This is caused by HostCheck::isNotInternalHost() function relying on PHP's filter_var(..., FILTER_VALIDATE_IP), which does not recognize alternative IP formats, causing the validation to fall through to a DNS lookup that returns no records and incorrectly treats the host as safe, however the cURL subsequently normalizes the address and connects to the loopback destination. Through the confirmed /api/v1/Attachment/fromImageUrl endpoint, an authenticated user can force the server to make requests to loopback-only services and store the fetched response as an attachment. This vulnerability is distinct from CVE-2023-46736 (which involved redirect-based SSRF) and may allow access to internal resources reachable from the application runtime. This issue has been fixed in version 9.3.4.
CVE-2026-34719Med0.284.30.00Apr 8, 2026Zammad is a web based open source helpdesk/customer support system. Prior to 7.0.1 and 6.5.4, the webhook model was missing a proper validation for loop back addresses, or link-local addresses — only the URL scheme (HTTP/HTTPS) as well as the hostname was checked. This could end up in retrieving confidential metadata of cloud/hosting providers. The existing check is now extended and is applied when configuring webhooks as well as triggering webhook jobs. This vulnerability is fixed in 7.0.1 and 6.5.4.
CVE-2026-34753Med0.285.40.00Apr 6, 2026vLLM is an inference and serving engine for large language models (LLMs). From 0.16.0 to before 0.19.0, a server-side request forgery (SSRF) vulnerability in download_bytes_from_url allows any actor who can control batch input JSON to make the vLLM batch runner issue arbitrary HTTP/HTTPS requests from the server, without any URL validation or domain restrictions. This can be used to target internal services (e.g. cloud metadata endpoints or internal HTTP APIs) reachable from the vLLM host. This vulnerability is fixed in 0.19.0.
CVE-2026-34590Med0.285.40.00Apr 2, 2026Postiz is an AI social media scheduling tool. Prior to version 2.21.4, the POST /webhooks/ endpoint for creating webhooks uses WebhooksDto which validates the url field with only @IsUrl() (format check), missing the @IsSafeWebhookUrl validator that blocks internal/private network addresses. The update (PUT /webhooks/) and test (POST /webhooks/send) endpoints correctly apply @IsSafeWebhookUrl. When a post is published, the orchestrator fetches the stored webhook URL without runtime validation, enabling blind SSRF against internal services. This issue has been patched in version 2.21.4.
CVE-2026-4989Med0.284.30.00Apr 1, 2026Improper input validation in the gateway health check feature in Devolutions Server allows a low-privileged authenticated user to perform server-side request forgery (SSRF), potentially leading to information disclosure, via a crafted API request. This issue affects Server: from 2026.1.1 through 2026.1.11, from 2025.3.1 through 2025.3.17.
CVE-2026-3530Med0.284.30.00Mar 26, 2026Server-Side Request Forgery (SSRF) vulnerability in Drupal OpenID Connect / OAuth client allows Server Side Request Forgery.This issue affects OpenID Connect / OAuth client: from 0.0.0 before 1.5.0.

CVE-2025-71258Med0.284.30.02Mar 19, 2026BMC FootPrints ITSM versions 20.20.02 through 20.24.01.001 contain a blind server-side request forgery vulnerability in the searchWeb API component that allows authenticated attackers to cause the server to initiate arbitrary outbound requests. Attackers can exploit improper URL validation to perform internal network scanning or interact with internal services, impacting system availability. The following hotfixes remediate the vulnerability: 20.20.02, 20.20.03.002, 20.21.01.001, 20.21.02.002, 20.22.01, 20.22.01.001, 20.23.01, 20.23.01.002, and 20.24.01.
CVE-2026-28295Med0.284.30.00Feb 26, 2026A flaw was found in the FTP GVfs backend. A malicious FTP server can exploit this vulnerability by providing an arbitrary IP address and port in its passive mode (PASV) response. The client unconditionally trusts this information and attempts to connect to the specified endpoint, allowing the malicious server to probe for open ports accessible from the client's network.
