GHSA-MV93-W799-CJ2W GitPython: Newline injection in config_writer() section parameter bypasses CVE-2026-42215 patch, enabling RCE via core.hooksPath

Summary The patch for CVE-2026-42215 GitPython 3.1.49 validates newlines only in the value parameter of setvalue. The section and option parameters are passed to configparser without any newline validation. An attacker who controls the section argument can inject \n to write arbitrary section...

CVE-2026-44244 GitPython: Newline injection in config_writer().set_value() enables RCE via core.hooksPath

GitPython is a python library used to interact with Git repositories. Prior to version 3.1.49, GitConfigParser.setvalue passes values to Python's configparser without validating for newlines. GitPython's own write converts embedded newlines into indented continuation lines e.g. \n becomes \n\t, b...

GitPython: Newline injection in config_writer().set_value() enables RCE via core.hooksPath

GitConfigParser.setvalue passes values to Python's configparser without validating for newlines. GitPython's own write converts embedded newlines into indented continuation lines e.g. \n becomes \n\t, but Git still accepts an indented core stanza as a section header — so the injected core.hooksPa...
