SCA: security update for flawfinder (GHSA-4c3c-r6p8-c863)

high Tenable Self-Hosted Container Security Plugin ID 444075

Description

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

 - Flawfinder is a a static analysis tool for finding vulnerabilities in C/C++ source code. Versions prior to
 2.0.20 have an improper input neutralization issue leading to output manipulation, specifically,
 Terminal/ANSI Escape Sequence Injection and XML Injection. A malicious file whose name contains ANSI
 escape sequences can end up being included in flawfinder's standard terminal output, with many effects.
 Untrusted fields (such as filenames, categories, or code context text) were not properly sanitized when
 generating structured reports. An attacker could exploit this to corrupt CSV formats or inject arbitrary
 XML attributes into SonarQube outputs via output_sonar(). It impacts those who use flawfinder to evaluate
 intentionally malicious filenames or file contents. This issue has been fully patched in Version 2.0.20
 (released 2026-05-16). There is no configuration-based workaround within older versions of flawfinder. If
 an immediate upgrade is not possible, users can mitigate the risk by pre-scanning filenames, inspecting
 raw output, and/or restricting untrusted inputs. (CVE-2026-48813)

Solution

Update the flawfinder library and its related packages to version 2.0.20 or later.
