The undertow client is not checking the server identity presented by the server certificate in https connections. This is a compulsory step (at least it should be performed by default) in https and in http/2. I would add it to any TLS client protocol.

link_to_local_path in ebooks/conversion/plugins/html_input.py in calibre before 6.19.0 can, by default, add resources outside of the document root.

A flaw was found in Keycloak before 13.0.0, where it is possible to force the server to call out an unverified URL using the OIDC parameter request_uri. This flaw allows an attacker to use this parameter to execute a Server-side request forgery (SSRF) attack.

Server-Side Request Forgery in Canvas LMS 2020-07-29 allows a remote, unauthenticated attacker to cause the Canvas application to perform HTTP GET requests to arbitrary domains.

DNN (formerly DotNetNuke) is an open-source web content management platform (CMS) in the Microsoft ecosystem. A bypass has been identified for the previously known vulnerability CVE-2017-0929, allowing unauthenticated attackers to execute arbitrary GET requests against target systems, including internal or adjacent networks. This vulnerability facilitates a semi-blind SSRF attack, allowing attackers to make the target server send requests to internal or external URLs without viewing the full responses. Potential impacts include internal network reconnaissance, bypassing firewalls. This vulnerability is fixed in 9.13.8.

A vulnerability in Cisco TelePresence Video Communication Server (VCS) and Cisco Expressway Series software could allow an unauthenticated, remote attacker to cause an affected system to send arbitrary network requests. The vulnerability is due to improper restrictions on network services in the affected software. An attacker could exploit this vulnerability by sending malicious requests to the affected system. A successful exploit could allow the attacker to send arbitrary network requests sourced from the affected system.

Apache Batik is vulnerable to server-side request forgery, caused by improper input validation by the "xlink:href" attributes. By using a specially-crafted argument, an attacker could exploit this vulnerability to cause the underlying server to make arbitrary GET requests.

rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source.

A Server-Side Request Forgery (SSRF) vulnerability was identified in the Requests utility of significant-gravitas/autogpt versions prior to v0.4.0. The vulnerability arises due to a hostname confusion between the `urlparse` function from the `urllib.parse` library and the `requests` library. A malicious user can exploit this by submitting a specially crafted URL, such as `http://localhost:\@google.com/../`, to bypass the SSRF check and perform an SSRF attack.

A vulnerability in Cisco Finesse could allow an unauthenticated, remote attacker to bypass access controls and conduct a server-side request forgery (SSRF) attack on an affected system. The vulnerability exists because the affected system does not properly validate user-supplied input. An attacker could exploit this vulnerability by sending a crafted request to a user of the web application. A successful exploit could allow the attacker to access the system and perform unauthorized actions.

A Server-Side Request Forgery vulnerability in the SonicOS SSH management interface allows a remote attacker to establish a TCP connection to an IP address on any port when the user is logged in to the firewall.

The curl URL parser wrongly accepts percent-encoded URL separators like '/'when decoding the host name part of a URL, making it a *different* URL usingthe wrong host name when it is later retrieved.For example, a URL like `http://example.com%2F127.0.0.1/`, would be allowed bythe parser and get transposed into `http://example.com/127.0.0.1/`. This flawcan be used to circumvent filters, checks and more.

SSRF in Apache HTTP Server with mod_proxy loaded allows an attacker to send outbound proxy requests to a URL controlled by the attacker.  Requires an unlikely configuration where mod_headers is configured to modify the Content-Type request or response header with a value provided in the HTTP request. Users are recommended to upgrade to version 2.4.64 which fixes this issue.

Rollup 18 for Microsoft Exchange Server 2010 SP3 and previous versions has an SSRF vulnerability via the username parameter in /owa/auth/logon.aspx in the OWA (Outlook Web Access) login page.

Microsoft ADFS 4.0 Windows Server 2016 and previous (Active Directory Federation Services) has an SSRF vulnerability via the txtBoxEmail parameter in /adfs/ls.

The MailConnect feature on D-Link Central WiFiManager CWM-100 1.03 r0098 devices is intended to check a connection to an SMTP server but actually allows outbound TCP to any port on any IP address, leading to SSRF, as demonstrated by an index.php/System/MailConnect/host/127.0.0.1/port/22/secure/ URI.

In WordPress before 4.7.5, there is insufficient redirect validation in the HTTP class, leading to SSRF.

Zoho ManageEngine ADSelfService Plus before 6112 is vulnerable to SSRF.

SSRF exists in Webmin 1.850 via the PATH_INFO to tunnel/link.cgi, as demonstrated by a GET request for tunnel/link.cgi/http://INTRANET-IP:8000.

All request mappings in `StreamingCoordinatorController.java` handling `/kylin/api/streaming_coordinator/*` REST API endpoints did not include any security checks, which allowed an unauthenticated user to issue arbitrary requests, such as assigning/unassigning of streaming cubes, creation/modification and deletion of replica sets, to the Kylin Coordinator. For endpoints accepting node details in HTTP message body, unauthenticated (but limited) server-side request forgery (SSRF) can be achieved. This issue affects Apache Kylin Apache Kylin 3 versions prior to 3.1.2.

An issue was discovered in ProxyServlet.java in the /proxy servlet in Zimbra Collaboration Suite (ZCS) 8.8.15 and 9.0. The value of the X-Forwarded-Host header overwrites the value of the Host header in proxied requests. The value of X-Forwarded-Host header is not checked against the whitelist of hosts that ZCS is allowed to proxy to (the zimbraProxyAllowedDomains setting).
