Linux Distros Unpatched Vulnerability : CVE-2026-5038

high Nessus Plugin ID 341742

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

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

- Impact: multer versions 2.0.0-alpha.1 through 2.1.1 and 3.0.0-alpha.1 are vulnerable to a Denial of Service when using diskStorage. Aborted or malformed multipart uploads leave orphaned partial files on disk because the Readable.pipe() call does not propagate the stream destroy signal to the underlying fs.WriteStream. An attacker can exhaust disk space by triggering many aborted uploads, with no application bug required. Patches: Users should upgrade to multer 2.2.0 (2.x line) or 3.0.0-alpha.2 (3.x prerelease).
Both versions track in-flight write streams and clean them up on the abort path. Workarounds: None.
(CVE-2026-5038)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
