SCA: security update for bugsink (GHSA-fp53-qcf8-2xx2)

medium Tenable Self-Hosted Container Security Plugin ID 441518

Description

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

 - Bugsink is a self-hosted error tracking tool. Prior to 2.1.3, Bugsink’s webhook URL validation could be
 (partially) bypassed because of a mismatch in URL parsing. The original validation logic parsed webhook
 URLs with Python’s urllib.parse.urlparse, then sent the request with requests.post. For malformed inputs
 involving backslashes and @, those components can disagree about where the authority ends and which
 hostname is the real target. A URL may therefore appear to target an allowlisted public hostname during
 validation, while the HTTP client actually connects to a different host. This vulnerability is fixed in
 2.1.3. (CVE-2026-44502)

Solution

Update the bugsink library and its related packages to version 2.1.3 or later.
