Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Flawfinder versions before 2.0.20 are affected by output manipulation: filenames and source text containing ANSI escape sequences or other unsanitized fields can alter terminal, CSV, and SonarQube XML output. An attacker who supplies a scanned file with a malicious name or content could hide scan results from a reviewer or inject XML attributes. Upgrade to flawfinder 2.0.20 or later.
