PYSEC-2026-2532 Jupyter Server vulnerable to Path Traversal via incorrect root directory boundary check in _get_os_path()

A path traversal vulnerability exists in jupyter-server version 2.17.0 due to an incorrect root directory boundary check in the getospath function within jupyterserver/services/contents/fileio.py. The check uses startswithroot without appending a trailing path separator, allowing sibling...

PYSEC-2026-2426 compliance-trestle Profile Import has an Arbitrary File Read via trestle:// URI and Relative Path Traversal

Summary The compliance-trestle library's profile import mechanism resolves trestle:// URIs and relative file paths by joining them with trestleroot and calling .resolve, but performs no boundary check to ensure the resolved path stays within the trestle workspace. An attacker can craft a maliciou...

PYSEC-2026-2999 Regression in pymdownx.snippets reintroduces sibling-prefix path traversal bypass despite restrict_base_path

Summary pymdownx.snippets has a regression of the CVE-2023-32309 / GHSA-jh85-wwv9-24hv fix. With restrictbasepath: True the default, the current filename.startswithbase containment check does not enforce a directory boundary. As a result, a markdown snippet directive can read files from sibling...

PYSEC-2026-2378 Microsoft APM: Windows absolute-path tar member overwrite during legacy-bundle probing in `apm install`

Summary Microsoft APM contains a Windows-specific archive extraction boundary failure in the legacy-bundle probe used by apm install on supported Python 3.10 and 3.11 runtimes. When apm install is given a local .tar.gz that is not recognized as a plugin-format bundle, APM probes whether it is a...

PYSEC-2026-2949 PraisonAIAgents: Arbitrary File Read via read_skill_file Missing Workspace Boundary and Approval Gate

Summary readskillfile in skilltools.py allows reading arbitrary files from the filesystem by accepting an unrestricted skillpath parameter. Unlike filetools.readfile which enforces workspace boundary confinement, and unlike runskillscript which requires critical-level approval, readskillfile has...

PYSEC-2026-2944 PraisonAIAgents: Path Traversal via Unvalidated Glob Pattern in list_files Bypasses Workspace Boundary

Summary The listfiles tool in FileTools validates the directory parameter against workspace boundaries via validatepath, but passes the pattern parameter directly to Path.glob without any validation. Since Python's Path.glob supports .. path segments, an attacker can use relative path traversal i...
