Linux Distros Unpatched Vulnerability : CVE-2026-39825

medium Nessus Plugin ID 313257

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.

 - ReverseProxy can forward queries containing parameters not visible to Rewrite functions. When used with a Rewrite function, or a Director function which parses query parameters, ReverseProxy sanitizes the forwarded request to remove query parameters which are not parsed by url.ParseQuery. ReverseProxy does not take ParseQuery's limit on the total number of query parameters (controlled by GODEBUG=urlmaxqueryparams=N) into account. This can permit ReverseProxy to forward a request containing a query parameter that is not visible to the Rewrite function. For example, the query a1=x&a2=x&...&a10000=x&hidden=y can forward the parameter hidden=y while hiding it from the proxy's Rewrite function. (CVE-2026-39825)

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

Solution

There is no known solution at this time.
