CVE-2026-55994 (GCVE-0-2026-55994)

Vulnerability from cvelistv5 – Published: 2026-07-06 08:13 – Updated: 2026-07-06 21:13

Title
Apache Camel Iggy: The inbound consumer maps externally-supplied Iggy message user-headers into the Exchange without a HeaderFilterStrategy, allowing injection of Camel control headers - enabling control over internal behaviour
Summary
Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Iggy component. The camel-iggy consumer mapped the user-headers of inbound Iggy messages into the Camel Exchange header map without applying any HeaderFilterStrategy (IggyFetchRecords copied the message user-headers straight into the Exchange). Because nothing blocked the Camel header namespace, an actor able to publish to the consumed Iggy stream/topic could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as message user-headers. In a route where the Iggy consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable reference, an application property, or a vault reference - are resolved to their real values and sent to the attacker, disclosing environment variables, application properties and vault secrets. This issue affects Apache Camel: from 4.17.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix adds a dedicated IggyHeaderFilterStrategy (and a headerFilterStrategy endpoint option) that filters the Camel header namespace case-insensitively on inbound mapping, so externally-supplied Camel* / camel* headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from the inbound message before they reach any downstream producer (for example removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route), restrict who can publish to the consumed Iggy stream/topic, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.

Title
Apache Camel Atmosphere Websocket: The inbound consumer maps externally-supplied WebSocket query parameters into the Exchange without a HeaderFilterStrategy, allowing injection of Camel control headers - enabling influencing internal behaviour
Summary
Improper Input Validation, Exposure of Sensitive Information to an Unauthorized Actor, Server-Side Request Forgery (SSRF) vulnerability in Apache Camel in Atmosphere Websocket Component. The camel-atmosphere-websocket consumer mapped inbound WebSocket query parameters into the Camel Exchange header map without applying any HeaderFilterStrategy (WebsocketConsumer.sendEventNotification() iterates the query-string map collected in WebsocketConsumer.service() and copies each entry into the Exchange). Because nothing blocked the Camel header namespace, a client connecting to the WebSocket endpoint could set Camel-internal control headers - including CamelHttpUri (Exchange.HTTP_URI) - simply by supplying them as query parameters. In a route where the WebSocket consumer feeds a downstream HTTP producer, the injected CamelHttpUri redirects the server-side HTTP request to an attacker-chosen destination (server-side request forgery - for example to an internal service or a cloud metadata endpoint). In addition, the HTTP producer resolves Camel property placeholders on the resulting (attacker-controlled) URI, so placeholders embedded in the injected value - such as an environment-variable reference, an application property, or a vault reference - are resolved to their real values and sent to the attacker, disclosing environment variables, application properties and vault secrets. When the WebSocket endpoint is exposed without authentication, this is reachable by an unauthenticated remote attacker. This issue affects Apache Camel: from 4.0.0 before 4.14.8, from 4.15.0 before 4.18.3, from 4.19.0 before 4.21.0. Users are recommended to upgrade to version 4.21.0, which fixes the issue. If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.8. If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.3. The fix makes the consumer apply the HeaderFilterStrategy it already inherits from the HTTP/servlet stack, filtering the Camel header namespace case-insensitively on inbound mapping, so externally-supplied Camel* / camel* headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from the inbound message before they reach any downstream producer (for example removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route), require authentication on the WebSocket endpoint, and avoid bridging an untrusted consumer directly into an HTTP producer whose target URI can be driven from message headers.

Title
Apache Hive: SSRF vulnerability in Hive Avro Serde due to Insufficient input validation on avro.schema.url
Summary
Server-Side Request Forgery (SSRF) in Avro SerDe schema resolution in Apache Hive before 4.2.1 allows an authenticated remote attacker with CREATE TABLE privilege to cause the Hive server to fetch an attacker-controlled URL when resolving the avro.schema.url table property on an Avro table that is subsequently queried. This can expose cloud instance metadata, internal network services, or local server files to the Hive process identity. Users are recommended to upgrade to version 4.2.1, which fixes this issue. Attacker access requirements: * Network access to HiveServer2 / Metastore: required (remote attacker model). * Valid Hive authentication: required. * CREATE TABLE (or equivalent) privilege: required, so the attacker can set avro.schema.url in table properties. * SELECT privilege on the malicious table: not required for the creator, who can typically query their own table; any other user granted SELECT can also trigger the fetch. * Write access to the table LOCATION: not required; the attack uses the schema URL, not the data path. * Admin / superuser privileges: not required; an ordinary authenticated user with DDL rights is sufficient. * External tables enabled: typically required in practice, and enabled by default in most deployments. Detection guidance: * Inspect metastore / Hive table metadata for Avro tables whose avro.schema.url uses unexpected schemes such as http, https, file, or ftp, or points at link-local / cloud metadata addresses (for example 169.254.169.254) or other internal hosts. * Review HiveServer2 and Metastore logs around CREATE/ALTER TABLE and queries against Avro tables for schema-resolution failures or outbound fetches of avro.schema.url. * Correlate CREATE TABLE / ALTER TABLE activity that sets avro.schema.url with subsequent SELECT activity on the same table, especially when the URL target is unusual for schema distribution. * On cloud deployments, check instance / VPC flow logs and metadata service access logs for unexpected requests from Hive host identities shortly after Avro DDL or query activity.

CVE-2026-55791 (GCVE-0-2026-55791)

Title
Craft CMS: Blind SSRF and Arbitrary JavaScript Injection via Host Header Poisoning in actionResourceJs
Summary
Craft CMS is a content management system (CMS). Versions 4.0.0-RC1 and above, prior to 4.18.0 and 5.0.0-RC1, and above, prior to 5.10.0, are vulnerable to Server-Side Request Forgery (SSRF) and Arbitrary JavaScript Injection through the /actions/app/resource-js endpoint. By exploiting the default permissive trustedHosts configuration, an attacker can poison the Host or X-Forwarded-Host header to manipulate the application’s $baseUrl. This bypasses the endpoint’s internal URL validation, forcing the backend Guzzle client to fetch a malicious payload from an attacker-controlled server and reflect it to the client with a Content-Type: application/javascript header. The vulnerability manifests when assetManager.cacheSourcePaths is set to false. This issue has been fixed in versions 4.18.0 and 5.10.0.

Title
CC: Tweaked: Incomplete fix for GHSA-5jh9-2h63-pw4q: RFC 8215 NAT64 prefix (64:ff9b:1::/96) bypasses SSRF protection
Summary
CC: Tweaked is a mod for Minecraft which adds programmable computers, turtles, and more to the game. Prior to 1.120.0, the SSRF protection in projects/core/src/main/java/dan200/computercraft/core/apis/http/options/AddressPredicate.java blocks the RFC 6052 64:ff9b::/96 NAT64 prefix but omits the RFC 8215 64:ff9b:1::/48 local-use prefix. On a dual-stack server using RFC 8215 NAT64, an unauthenticated user who can execute Lua code can use http.request or http.websocket with an address under 64:ff9b:1::/48 to reach loopback, RFC 1918, cloud metadata, or internal API endpoints because PrivatePattern.matches() does not classify the mapped IPv6 address as private. This issue is fixed in version 1.120.0.

Title
ZITADEL: Server-Side Request Forgery (SSRF) and Denylist Bypass in Outgoing HTTP Components
Summary
ZITADEL is an open source identity management platform. From 4.0.0-rc.1 through 4.15.1, ZITADEL's HTTP notification channels, OIDC BackChannel Logout, and SAML metadata URL fetches do not consistently validate user-defined URLs against protected denylist handling, allowing server-side requests to loopback, internal IP, link-local, or redirected endpoints through DNS rebinding, redirects, or protocol downgrades. This issue is fixed in version 4.15.2.

CVE-2026-55641 (GCVE-0-2026-55641)

Vulnerability from cvelistv5 – Published: 2026-07-10 15:36 – Updated: 2026-07-10 19:06

Title
9router: Unauthenticated `/v1` proxy access via `Host`-header spoofing → open AI relay + SSRF
Summary
9Router is an AI router & token saver. Prior to 0.5.2, 9router determines whether a /v1 LLM proxy request is local by reading the client-controlled Host header, allowing a remote unauthenticated attacker to send Host: localhost and bypass API-key authentication. In the default configuration, this exposes the /v1 proxy to upstream provider calls using stored provider credentials and allows /v1/search with the searxng provider_options.baseUrl parameter to drive server-side requests to internal or cloud-metadata hosts. This issue is fixed in version 0.5.2.

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.
