websocket-driver is a WebSocket protocol handler with pluggable I/O. Prior to 0.7.5, if this library is used with the permessage-deflate extension, a WebSocket server or client can be made to accept messages that are larger than the configured maximum message size because the limit is checked against the message frames' length headers, which give the size of the compressed data, not the size after decompression in lib/websocket/driver/hybi.js. This can lead to applications accepting larger messages than expected and exceeding their intended resource usage. This issue is fixed in version 0.7.5.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21448-1 advisory.

    - CVE-2025-7783: form-data: unsafe `Math.random()` function is used to select a boundary value for     multipart       form-encoded data (bsc#1246822).
    - CVE-2026-12143: form-data: CRLF injection via unescaped multipart field names and filenames     (bsc#1272310).
    - CVE-2026-13149: brace-expansion: `expand()` function exhibits exponential-time complexity when     processing       non-expanding `{}` brace groups (bsc#1269927).
    - CVE-2026-13311: shell-quote: quadratic complexity in `parse()` function when processing specially     crafted strings       (bsc#1269359).
    - CVE-2026-13676: fast-uri: host-based policy bypass due to failure to canonicalize Unicode/IDN hostnames     for       HTTP-family URLs (bsc#1269595).
    - CVE-2026-27601: underscore: DoS via stack overflow due to missing depth limits in `_.flatten` and     `_.isEqual`       functions (bsc#1259169).
    - CVE-2026-40181: react-router: open redirect to an external domain due to path values starting with `//`     being       reinterpreted as protocol-relative URLs (bsc#1272311).
    - CVE-2026-49356: @babel/core: arbitrary file read via `sourceMappingURL` comment (bsc#1272317).
    - CVE-2026-53550: js-yaml: quadratic complexity in merge-key processing when processing a crafted YAML     document       (bsc#1268851).
    - CVE-2026-53632: launch-editor: NTLMv2 hash disclosure via UNC path handling on Windows (bsc#1272319).
    - CVE-2026-54466: websocket-driver: message corruption via abuse of protocol length headers (bsc#1272312).
    - CVE-2026-54490: websocket-driver: resource limit bypass via message compression (bsc#1272313).
    - CVE-2026-55602: http-proxy-middleware: Host-header-driven backend routing bypass via `router` host+path     substring       matching (bsc#1272318).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
