GitPython: Environment-variable exfiltration via os.path.expandvars() on Repo.clone_from() URL

SummaryRepo.clonefrom passes the caller-supplied remote URL through Git.polishurl, which on every non-Cygwin platform calls os.path.expandvars on the URL before handing it to git clone. An attacker who controls the URL argument — the documented use case for clonefrom in "import repository from UR...

CVE-2026-67322

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...

PraisonAIAgents: Environment Variable Secret Exfiltration via os.path.expandvars() Bypassing shell=False in Shell Tool

SummaryThe executecommand function in shelltools.py calls os.path.expandvars on every command argument at line 64, manually re-implementing shell-level environment variable expansion despite using shell=False line 88 for security. This allows exfiltration of secrets stored in environment variable...
