In versions 3.2.2 and earlier and version 4.0.0, auth0/node-jws has an improper signature verification vulnerability when using the HS256 algorithm under specific conditions. Applications are affected when they use the jws.createVerify() function for HMAC algorithms and use user-provided data from the JSON Web Signature protected header or payload in HMAC secret lookup routines, which can allow attackers to bypass signature verification. This issue has been patched in versions 3.2.3 and 4.0.1. ## Affected - `node-jws < 3.2.3` - `node-jws = 4.0.0` ## Remediation Upgrade past the affected range: - `node-jws 3.2.3` ## Vendor advisories - **RHSA-2026:0261** · Red Hat · fixed in: Red Hat Developer Hub 1.7 · released 2026-01-07 · [advisory](https://access.redhat.com/errata/RHSA-2026:0261) - **RHSA-2026:0531** · Red Hat · fixed in: Red Hat Developer Hub 1.8 · released 2026-01-13 · [advisory](https://access.redhat.com/errata/RHSA-2026:0531) - **RHSA-2026:2456** · Red Hat · fixed in: Red Hat OpenShift Dev Spaces (RHOSDS) 3.26 · released 2026-02-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:2456) - **RHSA-2026:2762** · Red Hat · fixed in: Red Hat Quay 3.10 · released 2026-02-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:2762) - **RHSA-2026:1730** · Red Hat · fixed in: Red Hat Quay 3.12 · released 2026-02-02 · [advisory](https://access.redhat.com/errata/RHSA-2026:1730) - **RHSA-2026:4185** · Red Hat · fixed in: Red Hat Quay 3.13 · released 2026-03-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:4185) - **RHSA-2026:4215** · Red Hat · fixed in: Red Hat Quay 3.14 · released 2026-03-10 · [advisory](https://access.redhat.com/errata/RHSA-2026:4215) - **RHSA-2026:1942** · Red Hat · fixed in: Red Hat Quay 3.15 · released 2026-02-04 · [advisory](https://access.redhat.com/errata/RHSA-2026:1942) - **RHSA-2026:2681** · Red Hat · fixed in: Red Hat Quay 3.16 · released 2026-02-12 · [advisory](https://access.redhat.com/errata/RHSA-2026:2681) - **RHSA-2026:2754** · Red Hat · fixed in: Red Hat Quay 3.9 · released 2026-02-16 · [advisory](https://access.redhat.com/errata/RHSA-2026:2754) - **RHSA-2026:2921** · Red Hat · fixed in: Red Hat Trusted Artifact Signer 1.2 · released 2026-02-18 · [advisory](https://access.redhat.com/errata/RHSA-2026:2921) - **Red Hat VEX** · Important · affected: Red Hat build of Apicurio Registry 2, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift Container Platform 4, Red Hat Openshift Data Foundation 4 · no fix planned: Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift Container Platform 4, Red Hat build of Apicurio Registry 2, Red Hat Openshift Data Foundation 4 · updated 2026-09-09 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2025/cve-2025-65945.json)
