CVE-2026-67322: Exposure of Sensitive Information to an Unauthorized Actor

GitPython before 3.1.52 is vulnerable to environment-variable exfiltration in Repo.clonefrom. The caller-supplied remote URL is passed through Git.polishurl, which on non-Cygwin platforms calls os.path.expandvars on the URL before invoking git clone. An attacker who controls the clone URL can emb...

python: Quadratic complexity in os.path.expandvars() with user-controlled template

A vulnerability in Python’s os.path.expandvars function that can cause performance degradation. When processing specially crafted, user-controlled input with nested environment variable patterns, the function exhibits quadratic time complexity, potentially leading to excessive CPU usage and denia...
