SCA: security update for miniflux.app/v2 (GHSA-xwh2-742g-w3wp)

medium Tenable Cloud Security Plugin ID 436611

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Miniflux 2 is an open source feed reader. Prior to version 2.2.16, Miniflux's media proxy endpoint (`GET
 /proxy/{encodedDigest}/{encodedURL}`) can be abused to perform Server-Side Request Forgery (SSRF). An
 authenticated user can cause Miniflux to generate a signed proxy URL for attacker-chosen media URLs
 embedded in feed entry content, including internal addresses (e.g., localhost, private RFC1918 ranges, or
 link-local metadata endpoints). Requesting the resulting `/proxy/...` URL makes Miniflux fetch and return
 the internal response. Version 2.2.16 fixes the issue. (CVE-2026-21885)
