PYSEC-2026-3809 asyncssh has an incomplete fix for CVE-2026-45309 — AuthorizedKeysFile %u still escapes the intended directory via a leading ~ (and weakly via ${ENV}) username substitution
Incomplete fix for CVE-2026-45309 GHSA-g794-3fmp-753h. The 2.23.0 guard that sanitises the SSH username before %u substitution in AuthorizedKeysFile blocks /, \ and .., but does not block a leading or $ENV, both of which are re-introduced by later expansion and reach the file open — defeating the...
gitpython: GitPython: Environment variable exfiltration via attacker-controlled clone URL
A flaw was found in GitPython. A remote attacker can exploit a vulnerability in the Repo.clonefrom method by providing a specially crafted Git repository URL. This URL can contain references to environment variables, which are then expanded and included in the URL. This allows the attacker to...
Insertion of Sensitive Information Into Sent Data
Overview GitPython is a python library used to interact with Git repositories Affected versions of this package are vulnerable to Insertion of Sensitive Information Into Sent Data via Git.polishurl in Repo.clonefrom and the stored-origin normalization path in git/repo/base.py. An attacker can mak...
