    CVE-2026-78329Source published Source updated

    This bulletin covers 2 CVEs. The products, versions, score and guidance below describe the bulletin; check its source for applicability to this specific CVE.

    Improper input validation vulnerability in Apache Camel Undertow component. This issue affects Apache Camel: from 4.11.0 before 4.14.9, from 4.15.0 before 4.18.4, from 4.19.0 before 4.22.0. UndertowEndpoint defaulted its headerFilterStrategy field to the base HttpHeaderFilterStrategy and pushed that instance into the UndertowHttpBinding it creates lazily, overwriting the UndertowHeaderFilterStrategy that DefaultUndertowHttpBinding installs in its own constructor.

    Source-reported fixed versions

    Mitigation guidance
    • Users are recommended to upgrade to version 4.22.0, which fixes the issue.
    • If users are on the 4.14.x LTS releases stream, then they are suggested to upgrade to 4.14.9.
    • If users are on the 4.18.x releases stream, then they are suggested to upgrade to 4.18.4.
    • For deployments that cannot upgrade immediately, configure the strategy explicitly rather than relying on the default, for example by binding an UndertowHeaderFilterStrategy in the registry and referencing it on the endpoint as undertow:http://0.0.0.0:8080/foo?headerFilterStrategy=#myStrategy, and additionally strip the dispatch headers at the trust boundary with removeHeaders(“websocket.*”).
