SCA: security update for gogs.io/gogs (GHSA-3w28-36p9-w929)

medium Tenable Cloud Security Plugin ID 443808

Description

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

 - Gogs is an open source self-hosted Git service. Prior to 0.14.3, the Jupyter Notebook (ipynb) sanitizer
 endpoint at POST /-/api/sanitize_ipynb allows arbitrary data: URIs without proper restrictions,
 potentially leading to Cross-Site Scripting (XSS). The endpoint uses bluemonday.UGCPolicy() with
 p.AllowURLSchemes("data") which permits all data URI schemes including data:text/html, enabling attackers
 to inject malicious HTML/JavaScript. Additionally, the endpoint has no authentication middleware, allowing
 any registered user to exploit this vulnerability. This vulnerability is fixed in 0.14.3. (CVE-2026-52816)

Solution

Update the gogs.io/gogs library and its related packages to version 0.14.3 or later.
