An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-46454 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.apache.camel:camel-cometd (Maven): affected from 4.0.0; fixed in 4.14.8\n- org.apache.camel:camel-cometd (Maven): affected from 4.0.0; fixed in 4.14.8\n- org.apache.camel:camel-cometd (Maven): affected from 4.15.0; fixed in 4.18.3\n- org.apache.camel:camel-cometd (Maven): affected from 4.15.0; fixed in 4.18.3\n- org.apache.camel:camel-cometd (Maven): affected from 4.19.0; fixed in 4.21.0\n- org.apache.camel:camel-cometd (Maven): affected from 4.19.0; fixed in 4.21.0\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-46454/ (Markdown: https://insights.sbomify.com/CVE-2026-46454/index.md)","id":"CVE-2026-46454","markdown":"https://insights.sbomify.com/CVE-2026-46454/index.md","name":"CVE-2026-46454","record":{"aliases":["GHSA-r9cc-j7wr-p329"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache Camel Cometd component","requires_auth":"none","summary":"Unauthenticated attackers can inject Camel control headers via CometD messages, potentially redirecting producers or modifying data flow in Apache Camel routes.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"camel","vendor":"apache"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Improper Input Validation vulnerability in Apache Camel Cometd Component.\n\nThe camel-cometd component maps inbound Bayeux (CometD) message headers into the Camel Exchange without applying a HeaderFilterStrategy. CometdBinding.populateExchangeFromMessage copies the entire ext.CamelHeaders map supplied by the CometD client directly onto the Camel message (message.setHeaders), so any header name - including Camel-internal control headers such as CamelHttpUri, CamelFileName or CamelJmsDestinationName - is accepted unmodified. Because a CometdComponent installs no Bayeux SecurityPolicy by default, any client that can complete the Bayeux handshake against the CometD endpoint can publish such a message without authentication. An attacker can therefore inject arbitrary Camel control headers that influence the behaviour of downstream producers in the route (for example redirecting an HTTP producer, changing a file name, or overriding a JMS destination); the injected headers also persist across internal direct, seda and vm hops. The concrete downstream impact depends on which producers the route uses.\nThis 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.\n\nUsers 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 implements a HeaderFilterStrategy in the camel-cometd binding (a long-standing TODO in the code) that filters the Camel header namespace case-insensitively on inbound mapping, so client-supplied Camel* / camel* headers are no longer copied into the Exchange. For deployments that cannot upgrade immediately, strip the Camel control headers from inbound CometD messages before they reach any downstream producer (for example removeHeaders('Camel*') and removeHeaders('camel*') at the start of the route), and install an explicit Bayeux SecurityPolicy on the CometdComponent so that only authenticated clients can publish.","ecosystems":["Maven"],"exploits":{"exploitdb":0,"first_seen":"2026-07-13","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-07-13T12:58:04Z","kind":"github_poc","ref":"https://github.com/oscerd/CVE-2026-46454","stars":0,"title":"Reproducer
