## What is CVE-2026-40152?

CVE-2026-40152 is a medium-severity path traversal vulnerability in MervinPraison PraisonAIAgents, published on 9 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

PraisonAIAgents is a multi-agent teams system. Prior to 1.5.128, he list_files() tool in FileTools validates the directory parameter against workspace boundaries via _validate_path(), 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 in the glob pattern to enumerate arbitrary files outside the workspace, obtaining file metadata (existence, name, size, timestamps) for any path on the filesystem. This vulnerability is fixed in 1.5.128.

Weakness: CWE-22 (Improper Limitation of a Pathname to a Restricted Directory)

Check this codebase for CVE-2026-40152 and fix it if it is affected.

What it is: CVE-2026-40152 is a medium-severity path traversal vulnerability in MervinPraison PraisonAIAgents, published on 9 Apr 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-40152 exists.

Affected packages and fixed versions:
- praisonaiagents (PyPI): affected all versions; fixed in 1.5.128
- praisonaiagents (PyPI): affected all versions; fixed in 1.5.128
- praisonaiagents (PyPI): affected all versions; fixed in 1.5.128

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
