SCA: security update for undici (GHSA-vxpw-j846-p89q)
high Tenable Self-Hosted Container Security Plugin ID 443580
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Impact: The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a
message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream
many small or empty continuation frames that each pass per-frame and cumulative-size validation,
collectively causing unbounded memory growth in the client process. The result is memory exhaustion and a
denial of service. Affected applications are those using the undici WebSocket client (new WebSocket(...))
or the WebSocketStream API that can be induced to connect to an attacker-controlled or compromised
WebSocket endpoint. All releases starting at undici 6.17.0 are affected. Patches: Upgrade to undici >=
6.26.0, >= 7.28.0, or >= 8.5.0. Workarounds: No workaround is available. The fix must be applied through
an upgrade. (CVE-2026-12151)
Solution
Update the undici library and its related packages to version 6.27.0 or later.See Also
